Abstract

Objectives

The Stopping Cavities Trial investigated effectiveness and safety of 38% silver diamine fluoride in arresting caries lesions.

Materials and Methods

The study was a double-blind randomized placebo-controlled superiority trial with 2 parallel groups. The sites were Oregon preschools. Sixty-six preschool children with ≥1 lesion were enrolled. Silver diamine fluoride (38%) or placebo (blue-tinted water), applied topically to the lesion. The primary endpoint was caries arrest (lesion inactivity, Nyvad criteria) 14–21 days post intervention. Dental plaque was collected from all children, and microbial composition was assessed by RNA sequencing from 2 lesions and 1 unaffected surface before treatment and at follow-up for 3 children from each group.

Results and Conclusion

Average proportion of arrested caries lesions in the silver diamine fluoride group was higher (0.72; 95% CI; 0.55, 0.84) than in the placebo group (0.05; 95% CI; 0.00, 0.16). Confirmatory analysis using generalized estimating equation log-linear regression, based on the number of arrested lesions and accounting for the number of treated surfaces and length of follow-up, indicates the risk of arrested caries was significantly higher in the treatment group (relative risk, 17.3; 95% CI: 4.3 to 69.4). No harms were observed. RNA sequencing analysis identified no consistent changes in relative abundance of caries-associated microbes, nor emergence of antibiotic or metal resistance gene expression. Topical 38% silver diamine fluoride is effective and safe in arresting cavities in preschool children. The treatment is applicable to primary care practice and may reduce the burden of untreated tooth decay in the population.

In Vitro Efficacy of Essential Oil Mouthrinse versus Dentifrices

Journal of Dentistry

Available online 31 August 2017
Journal of Dentistry
Abstract

Objectives

To compare the antimicrobial efficacy and kill penetration of essential oils (EO) mouthrinse versus stannous fluoride, and triclosan dentifrice slurries on saliva-derived biofilms using confocal laser scanning microscopy (CLSM).

Methods

Saliva-derived biofilms were grown for 48 hours on hydroxyapatite discs using pooled, homogenized saliva from 8 healthy volunteers as the inoculum. The mean thickness of these biofilms was 84 μm (range, 23–241 μm). CLSM with viability mapping was used to visualize the antimicrobial kill penetration of each treatment regime within a biofilm.

Results

At 30 s treatment durations, CLSM imaging revealed greater antimicrobial activity and kill penetration of EO mouthrinse compared to sodium fluoride-, stannous fluoride-, and triclosan-containing dentifrice slurries. Quantification of biovolume revealed that EO mouthrinse treatment at 30 s resulted in a greater non-viable biovolume proportion (84.6% ± 15.0%) than other treatment groups. Increasing the treatment duration of the triclosan dentifrice (to 60 and 120 s) resulted in better penetration and an increased reduction of viable cells, comparable to EO mouthrinse treatment at 30 s duration. Further, CLSM imaging showed that the combined treatment of a non-antimicrobial dentifrice (45 s) with EO mouthrinse (30 s) showed superior antimicrobial activity (96.2% ± 3.7%) compared to the antimicrobial triclosan-containing dentifrice used without a mouthrinse step (26.0% ± 32.0%).

Conclusions

Within typical exposure times, the EO-containing mouthrinse can penetrate deep into the accumulating plaque biofilm compared to the chemotherapeutic dentifrice slurries, and may provide an efficacious alternative to triclosan, when used as an adjunct with a mechanical oral care regimen.

Clinical Significance

Using viability mapping and CLSM, this study demonstrated that EO-containing mouthrinse penetrates and kills microorganisms deeper and more effectively in plaque biofilm in typical exposure times when compared to dentifrice chemotherapeutic agents, providing an efficacious alternative to triclosan or stannous fluoride when used as an adjunct to mechanical oral care.

Carestream Dental Helps Doctors Make ‘Smart Choices’ for Equipment and Software


As a new freestanding digital dental company, Carestream Dental helps doctors make smart choices for their practices, whether they’re looking for equipment or software solutions. At the ADA Annual Meeting, Carestream Dental is showcasing both the latest intelligent scanning features of its CS 3600 intraoral scanner and new practice management solutions that make everyday workflow more intuitive.
“Smart technology is rapidly changing all sectors of industry, including digital dentistry,” Ed Shellard, D.M.D., Chief Dental Officer, Carestream Dental, said. “But being labeled as ‘smart’ doesn’t go far enough. Equipment and software needs to respond to users’ needs in real time and be intuitive to use.”
Intelligent scanning features, such as real-time feedback, are just a few of the updates to the CS 3600’s acquisition software algorithms. Rather than attempting multiple rescans or rendering an image only to find holes in the dataset, useful guides and feedback increase efficiency and enhance scan quality. If a scan lacks detail and requires additional scanning, green guide arrows indicate the ideal direction to rescan the missing information. Yellow highlights alert the user of gaps in the scan, while green highlights indicate holes in the data set.
“These quality check warnings make using the intraoral scanner more intuitive and help all users, from new to experienced, get an accurate, complete scan every time before they render the digital impression,” Shellard said.
New enhancements to the restorative workflow are also smart enough to detect and alert users to possible undercuts while the patient is still in the chair. If not suitable, the preparation can be adjusted and rescanned on the spot, rather than dealing with back-and-forth communications between the practice and lab, which could require the patient to return for an additional appointment.
A common issue in restorative cases is tissue collapse around preparations, which may affect the quality of the scan. To combat this, a convenient restoration locking tool lets users select and lock up to six previously scanned preparation areas. This preserves the area digitally in case of tissue collapse and also prevents the preparations from being updated when scanning the area a second time.
Updates have also been made to the implant-borne restorative workflow, such as a scanbody area selection tool, and the orthodontic workflow, which includes the ability to capture 2D “snapshots” from the digital scan for case documentation. Other improvements to image quality and clinical details include the ability to scan in high-resolution and color-coded occlusion mapping.
The CS 3600 also now offers the industry’s shortest autoclavable tip, perfect for posterior scanning. All of the scanner’s tips are autoclavable up to 60 times.*
Additionally, two significant new practice management solutions are being highlighted at ADA. First is the major release of CS SoftDent software v17, which provides exciting new features to streamline practice workflow for clinical and administrative users. A new clinical overview tab puts all the patient information, such as restorative and perio charts, in one place. Additional features include a patient banner that gives users easier access to patient information without exiting the chart, patient administration workflow enhancements that allow more than one user to work in a patient record and a refreshed user interface.
In addition to the latest enhancements to the software that dental practices already know and use, Carestream Dental is also offering an exclusive first look at a brand new software solution, coming soon. Attendees at ADA will be among the first to experience an innovative software platform that delivers a sophisticated but easy-to-use practice management solution for new and established practices of all sizes.
Supporting these two software announcements and seeking attendees’ feedback and first impressions is the popular Practice Management Pit Crew, comprised of Carestream Dental software developers, designers and experts.
For more information about the CS 3600 intraoral scanner or any of Carestream Dental’s software solutions, visit booth #1745 at the ADA Annual Meeting in Atlanta at the Georgia World Congress Center from Oct. 19-21 or call 800.944.6365 or visit www.carestreamdental.com.
*Tips can be autoclaved up to 60 times if the exposure is limited to 134 C at no more than four minutes and if gauze is used, as outlined in the CS 3600 Family Safety, Regulatory and Technical Specifications User Guide (9J8269)

Effect of toothpaste containing arginine on dental plaque—A randomized controlled in situ study

Journal of Dentistry

Available online 5 October 2017
Journal of Dentistry
Full Length Article
Abstract

Objectives

To evaluate the effects of 8% arginine-containing toothpaste on the dental plaque of no caries (NC) and high caries (HC) individuals in situ.

Methods

6 no caries (DMFT = 0) and 6 high caries (DMFT ≥ 6) individuals wearing a self-developed in situ dental plaque acquisition device were involved in a randomized double-blinded crossover study for 6 weeks: including lead-in (1 week), arginine-free (2 weeks), washout (2 weeks) and arginine-active (2 weeks) stages. The in situ plaque samples were collected at the endpoint of arginine-free and arginine-active stages and subjected to lactic acid production, metabolic activity, live/dead bacteria ratio and total biofilm biomass detections.

Results

The arginine-containing dentifrice reduced lactic acid production significantly in both the NC and HC groups, while the inhibitory abilities in the HC group were stronger than that in the NC group. In addition, the arginine-containing dentifrice didn’t significantly decrease the metabolic activity, live/dead bacteria ratio and total biofilm biomass in either the NC or the HC group.

Conclusions

Arginine-containing toothpaste can significantly reduce the lactic acid production from the in situ plaques to a low level without changing the metabolic activity, live/dead bacteria ratio and total biofilm biomass through a critical clinical randomized double-blinded crossover study.

Clinical significance

Arginine is a potential ecological prevention and control agent for dental caries. Meanwhile, the in situ model is an easy and pragmatic way to evaluate oral hygiene products (clinical trial registration: ChiCTR-INR-16010226).

NYU Dentistry receives $2.8 million as part of multi-center study to stop progression of cavities

NIH-funded study to test cavity-fighting liquid at three clinical sites

New York University




The National Institute of Dental & Craniofacial Research, part of the National Institutes of Health, has awarded a grant that will provide funding to New York University College of Dentistry (NYU Dentistry) and its collaborators to test the effectiveness of silver diamine fluoride in stopping the progression of cavities in young children.
The grant provides $9.8 million over four years, $2.8 million of which will come to NYU Dentistry, to fund a Phase III randomized controlled trial at three clinical sites: University of Michigan, University of Iowa, and NYU Dentistry. University of Michigan's Margherita Fontana, DDS, PhD, leads the study.
Cavities early in childhood are one of the most prevalent chronic conditions among U.S. children, especially those from low-income families. If allowed to progress untreated, cavities can have broad dental, medical, social, and quality of life consequences.
"Early childhood cavities are preventable, yet once they are established and left untreated they can have severe consequences on the health and wellness of both the affected children and the families that care for them," said Amr M. Moursi, DDS, PhD, chair of the Department of Pediatric Dentistry at NYU Dentistry and principal investigator at the NYU study site.
"For many young children who need extensive dental treatment, their only option is to undergo general anesthesia in order to receive fillings or extractions. Given the limited availability, potential risks, and high cost of general anesthesia in a hospital setting, we are interested in finding alternative methods to manage cavities."
Silver diamine fluoride was approved in the U.S. in 2014 for the treatment of dental hypersensitivity. However, it has been used for many years in other countries for cavity control. The liquid can be applied to a cavity to arrest tooth decay and in some cases replace the need for a filling or crown.
In 2016, the FDA designated silver diamine fluoride a "breakthrough therapy," a process which is designed to expedite drug development. This NIH-funded study will provide the necessary data for obtaining a cavity arrest drug claim for silver diamine fluoride in the U.S.
The study will closely follow more than 1,000 children, ages 2-5, enrolled in Head Start and other preschool programs. The researchers will treat children and monitor them over a school year to study the impact of silver diamine fluoride applied twice, six months apart, on cavity progression. They will also measure oral health-related quality of life and treatment satisfaction and acceptability.
"Should the trial be successful, the impact would be a change in the standard of care for the management of tooth decay in young children. It will also expand access to, and adoption of, a simple, non-invasive, inexpensive strategy for cavity management," said Moursi. "We hope that access to this simple treatment could also help in reducing oral health disparities."
Additional NYU Dentistry investigators include Drs. Yihong Li, Courtney Chinn, and Mark Wolff. The NYU Bluestone Center for Clinical Research will also collaborate on this study. In addition to investigators from the University of Michigan and the University of Iowa, the clinical trial includes researchers from Indiana University, University of Otago in New Zealand, University of Hong Kong and University of Baltimore. The grant (Award Number U01DE027372) began in September 2017.

The effect of local and systemic statin use as an adjunct to non-surgical and surgical periodontal therapy—A systematic review and meta-analysis

Journal of Dentistry

Available online 30 August 2017
Journal of Dentistry

Abstract

Objectives

To evaluate the effect of local and/or systemic statin use as an adjunct to non-surgical and/or surgical periodontal therapy.

Data

Literature search according to PRISMA guidelines with the following eligibility criteria: (a) English or German language; (b) interventional studies; (c) statins as monotherapy or as an adjunct to non-surgical and/or surgical treatment of periodontitis; (d) clinical and/or radiographic treatment effect size of statin intake reported.

Sources

Medline (PubMed), Embase (Ovid), CENTRAL (Ovid).

Study

selection Thirteen clinical studies regarding local application and 2 with systemic administration of statins as an adjunct to non-surgical treatment (SRP) and 4 studies regarding intrasurgical statin application with a maximum follow-up of 9 months could be included; simvastatin, atorvastatin, and rosuvastatin were used. Local but not systemic statin application as an adjunct to SRP yielded significantly larger probing pocket depth (PD), radiographic defect depth (RDD), and bleeding index reduction, and larger clinical attachment level gain, and less residual PD and RDD (p ≤ 0.016); rosuvastatin appeared as the most efficacious. Three of 4 studies reported a significant positive effect of intrasurgical statin application. No adverse events were reported after statin use. The vast majority of the included studies were from the same research group.

Conclusions

Significant additional clinical and radiographic improvements are obtained after local, but not systemic, statin use as an adjunct to SRP in deep pockets associated with intrabony defects and seemingly with furcation defects; intrasurgical statin application seems similarly beneficial. Confirmation of these results, and especially of the effect size, from other research groups is warranted.

AADOM ANNOUNCES SPECIALTY NETWORK PROGRAM

Red Bank, N.J., October 15, 2017 – The American Association of Dental Office Management (AADOM) is proud to launch a new initiative for office managers and practice administrators of specialty dental practices. This initiative was recently announced at the AADOM Annual Conference in Scottsdale, much to the enthusiasm of AADOM members. 
This program was created as a result of AADOM specialty members requesting to discuss challenges found in non-general dental practices. These unique situations include scheduling, marketing, billing & coding, specific to each specialty. AADOM responded to this challenge with the creation of the AADOM Specialty Network (ASN). Via the ASN, AADOM members will now have additional resources to help them navigate specialty specific management issues and to lead successful practices.  
Andrea Bowlin, FAADOM, Chairperson of the AADOM Oral Surgery Network states, “Specialty office managers face unique challenges in our practices. In oral surgery practices our relationships with our patients, education, billing/coding, and referral sources are specific to our specialty. The opportunity AADOM is extending to oral surgery specialty practices will help expand our knowledge through communication and education with office managers in similar practice settings.”  
Michael Cruz, FAADOM, Chairperson of the AADOM CEREC Network elaborates, “Specialty offices have their own set of challenges that may not always be addressed by GP offices. AADOM’s mission is to make sure that front office professionals know that they are not alone and the AADOM Specialty Network is just a continuation of that mission to bridge the gap for specialty offices.” 
There are several networks that are available to AADOM members. These include the AADOM Pediatric Network, the AADOM Orthodontic Network, the AADOM Multi-Specialty Network, The AADOM Periodontic Network, The AADOM Oral Surgery Network, the AADOM Endodontic Network, and the AADOM CEREC Network. 
Each Specialty Network will be chaired by an AADOM member. Benefits of the Specialty Networks include private online Facebook communities, specialty-specific educational webinars hosted by AADOM members and specialty-focused education at the AADOM Conference. 
Dentists are also enthusiastic about what the AADOM Specialty Networks will do for their practices. Oral Surgeon Charles E. Witkowski, Sr. DDS, MD, PhD states “We are the specialty that - while our background is in dentistry - we ride the fence between dentistry and medicine and face our unique challenges to address this. We stress education (dental and medical), relationships and communications with our colleagues, both specialists and general dentists. An excellent skill set is required for this. Equally important is a superb ability to communicate and mesh with our patients. The office manager must be the hub on a wheel with spokes radiating outward. The office manager should be able to teach, communicate and coordinate all aspects of the practice, a true leader. When this happens, the spokes attach to the rims of the wheel and the practice rolls along smoothly.” 
“The AADOM Specialty Network has been a long time coming,” says AADOM Founder and President Heather Colicchio. “Our specialty members clearly need additional resources to help them with what we have not covered for them - until now. The additional community, support and education we are rolling out for our specialty members will be an advantage to them in managing their practices and excelling in every way. We are excited to continue to expand our benefits to fill the needs of ALL of our members.” 
Also enthusiastic is Courtney Roberts, FAADOM, and Chairperson of the AADOM Endodontic Network: “I am thrilled to help this platform develop as the go-to resource for specialty managers; a place where we can stay connected to each other on familiar grounds while making sure our training game is focused and stronger than ever! And for those endo managers, you can expect our Facebook page to be full of videos, surveys, informative post, marketing ideas, FAQs and more!” 
About AADOM: The American Association of Dental Office Management (AADOM) is the nation's largest educational and networking association dedicated to serving dental practice management professionals. Our mission is to provide our members with networking, resources and education to help them achieve the highest level of professional development.

Effect of flowable composites on the clinical performance of non-carious cervical lesions: A systematic review and meta-analysis

Journal of Dentistry

Volume 65, October 2017, Pages 11-21
Journal of Dentistry
Review article


Abstract

Objectives

To answer the following PICO question (participant, intervention, comparator and outcome): Does flowable resin composite restorations compared with regular resin composites improve the marginal adaptation, marginal discoloration and retention rates of restorations placed in non-carious cervical lesions [NCCLs] of adults?, through a systematic review and meta-analysis.

Source

MEDLINE, Scopus, Web of Science, LILACS, BBO, Cochrane Library and SIGLE were searched without restrictions, as well as the abstracts of the IADR, clinical trials registries, dissertations and theses in May 2016 (updated in April 2017).

Study selection

We included randomized clinical trials (RCTs) that answered the PICO question. RCTs were excluded if cavities other than NCCLs were treated; indirect restorations; polyacid-based resins instead of composite resins were employed, restorations in primary teeth and restorations were placed in carious cervical lesions. The risk of bias tool of the Cochrane Collaboration was applied in the eligible studies and the GRADE tool was used to assess the quality of the evidence.

Data

After duplicates removal, 5137 articles were identified. After abstract and title screening, 8 studies remained. Six were at “unclear” risk of bias. The study follow-ups ranged from 1 to 3 years. No significant difference was observed between groups for loss of retention and marginal discoloration in all follow-ups. Better marginal adaptation was observed for restorations performed with flowable composites. At 1-year (risk ratio = 0.27 [0.10 to 0.70]) and 3-year (risk ratio = 0.34 [0.17 to 0.71]) follow-ups, flowable composites showed a risk 73% and 66% lower than regular composites for lack of adaptation, respectively. The evidence was graded as moderate quality for loss or retention at 3 years due to risk of bias and low and very low for all other outcomes due to risk of bias, imprecision and inconsistency.

Conclusions

We have moderate confidence that the resin composite viscosity does not influence the retention rates at 3 years. Similar marginal discoloration and better marginal adaptation was observed for flowable composites but the quality of evidence is doubtful. (PROSPERO CRD42015019560).

Intelligent Updates to CS 3600 Software Makes Implant Workflow Smarter





SAN FRANCISCO—When it was first launched in 2016, Carestream Dental’s CS 3600 intraoral scanner optimized the implant planning workflow. Today, the latest enhancements to the scanner’s acquisition software make introducing intraoral scanning into the implant workflow not just a smart choice, but a genius one.



The new intelligent scanning features of the CS 3600 make it easier to capture scans correctly on the first try, making scanning more efficient and resulting in higher quality scans before they’ve even been rendered. Missing information is color coded to indicate either holes or gaps and guide arrows recommend the best direction to scan to recapture the data. The ability to scan in high-resolution also improves quality and clinical details.



The scanner’s dedicated workflow, designed specifically for implant-borne restorative scanning, supported abutments and scanbodies, has also been updated with new features to make the digital implant workflow faster, smarter and more efficient. For example, dual scan mode allows the user to scan the same implant region of interest twice—once with the scanbody in place and once without—to capture more precise data.



When using multiple scanbodies on a single case, the new scanbody area selection tool lets users select the region around the scanbody to prevent an image mismatch. Then, the area where the scanbody is located is unselected. Finally, the new scan replaces only the area within the selected area.



“This uniquely designed tool was developed in direct response to feedback from current scanner users who are placing implants,” Ed Shellard, DMD, chief dental officer, Carestream Dental, said. “It significantly improves the quality of complex restoration cases with multiple-scan bodies for optimal implant-borne restorations.



Also new for all scanning workflows is color-coded occlusion mapping and a smaller third tip size. The new tip is the shortest autoclavable tip available and is designed for posterior scanning. All three of the CS 3600’s tips can be autoclaved up to 60 times.*



To learn more about all the latest features of the CS 3600, visit Carestream Dental at the AAOMS Annual Meeting in booth #1102, Oct. 12-14, Moscone Convention Center South, San Francisco, Calif.



For more information about the CS 3600 or any of Carestream Dental’s innovative solutions, call 800.944.6365 or visit www.carestreamdental.com.

 

* Tips can be autoclaved up to 60 times if the exposure is limited to 134˚C at no more than 4 minutes and if gauze is used, as outlined in the CS 3600 Family Safety, Regulatory, and Technical Specifications  User Guide (9J8269).

Wide diameter immediate post-extractive implants vs delayed placement of normal-diameter implants in preserved sockets in the molar region: 1-year post-loading outcome of a randomised controlled trial.

Eur J Oral Implantol. 2017;10(3):263-278.

Abstract

PURPOSE:

To compare the effectiveness of 6.0 to 8.0 mm-wide diameter implants, placed immediately after tooth extraction, with conventional 4.0 or 5.0 mm diameter implants placed in a preserved socket after a 4-month period of healing in the molar region.

MATERIALS AND METHODS:

Just after extraction of one or two molar teeth, and with no vertical loss of the buccal bone in relation to the palatal wall, 100 patients requiring immediate post-extractive implants were randomly allocated to immediate placement of one or two 6.0 to 8.0 mm-wide diameter implants (immediate group; 50 patients) or for socket preservation using a porcine bone substitute covered by a resorbable collagen barrier (delayed group; 50 patients), according to a parallel group design in one centre. Bone-to-implant gaps were filled with autogenous bone retrieved with a trephine drill used to prepare the implant sites for the immediate wide diameter post-extractive implants. Four months after socket preservation, one to two 4.0 or 5.0 mm-wide delayed implants were placed. Implants were loaded 4 months after placement with fixed provisional restorations in acrylic, and replaced after 4 months by fixed, definitive, metal-ceramic restorations. Patients were followed to 1 year after loading. Outcome measures were: implant failures, complications, aesthetics assessed using the pink esthetic score (PES), peri-implant marginal bone level changes, patient satisfaction, number of appointments and surgical interventions recorded, when possible, by blinded assessors.

RESULTS:

Three patients dropped out 1 year after loading from the immediate group vs six from the delayed group. Five implants out of 47 failed in the immediate group (10.6%) vs two out 44 (4.6%) in the delayed group, the difference being not statistically significant (difference in proportion = 6.0%, 95% CI: -8.8% to 20.8%, P = 0.436). In the immediate group 10 patients were affected by 10 complications, while in the delayed group four patients were affected by four complications. The difference was not statistically significant (difference in proportion = 12%, 95% CI: -2% to 26%, P = 0.084). At delivery of the definitive prostheses, 4 months after loading, the mean total PES score was 9.65 ± 1.62 and 10.44 ± 1.47 in the immediate and delayed groups, respectively. At 1 year after loading, the mean total PES score was 9.71 ± 2.71 and 10.86 ± 1.37 in the immediate and delayed groups, respectively. The Total PES score was statistically significantly better at delayed implants both at 4 months (mean difference = 0.79; 95% CI: 0.05 to 1.53; P = 0.03) and at 1 year (mean difference = 1.15; 95% CI: 0.13 to 2.17; P = 0.02). Marginal bone levels at implant insertion (after bone grafting) were 0.04 mm for immediate and 0.11 mm for delayed implants, which was statistically significantly different (mean difference = 0.07; 95% CI: 0.02 to 0.12; P < 0.0001). One year after loading, patients in the immediate group lost on average 1.06 mm and those from the delayed group 0.63 mm, the difference being statistically significant (mean difference = 0.43 mm; 95% CI: 0.15 to 0.61; P < 0.0001). All patients were fully or partially satisfied both for function and aesthetics, and would undergo the same procedure again both at 4 months and 1 year after loading. Patients from the immediate group required on average 7.48 ± 1.45 visits to the clinician and 2.14 ± 0.49 surgical interventions and to have their definitive prostheses delivered vs 10.30 ± 0.99 visits and 3.08 ± 0.40 surgical interventions for the delayed group, the difference being statistically significant (P < 0.001 for visits, and P < 0.001 for surgical interventions).

CONCLUSIONS:

Preliminary 1 year follow-up data suggest that immediate placement of 6.0 to 8.0 mm wide diameter implants in molar extraction sockets yielded inferior aesthetic outcomes than ridge preservation and delayed placement of conventional 4.0 to 5.0 mm diameter implants. Conflict of interest statement: This trial was partially funded by the manufacturer of the implants evaluated in this investigation (MegaGen Implant Co, Gyeongbuk, South Korea). However, data belonged to the authors and in no way did the manufacturer interfere with the conduct of the trial or the publication of its results.

Treating High-Caries Risk Occlusal Surfaces in First Permanent Molars through Sealants and Supervised Toothbrushing: A 3-Year Cost-Effective Analysis




Caries Res 2017;51:489-499

Abstract

We conducted a 3-year cost-effectiveness analysis on the cavitated dentine carious lesion preventive capabilities of composite resin (CR) (reference group) and atraumatic restorative treatment (ART) high-viscosity glass-ionomer cement (HVGIC) sealants compared to supervised toothbrushing (STB) in high-risk first permanent molars. School children aged 6-7 years in 6 schools (2 per group) received CR and ART/HVGIC sealants or STB daily for 180 days each school year. Data were collected prospectively and cost estimates were made for sample data and a projection of 1,000 sealants/STB high-risk permanent molars. Although STB had the best outcome, its high implementation cost (95% of cost for supervisors visiting schools 180 days/school year) affected the results. ART/HVGIC was cost-effective compared to CR for the sample data (savings of USD 37 per cavitated dentine carious lesion prevented), while CR was cost-effective compared to ART/HVGIC for the projection (savings of USD 17 per cavitated dentine carious lesion prevented), and both were cost-saving compared to STB. Two STB scenarios were tested in sensitivity analyses with variations in caries incidence and number of supervision days; results showed STB had lower costs and higher savings per cavitated dentine carious lesion prevented than CR and ART/HVGIC. A major assumption is that both scenarios have the same high effectiveness rate experienced by STB under study conditions; however, they point to the value of further research on the benefits of adopting STB as a long-term venture in a general population of school children.

Fixed vs removable complete arch implant prostheses: A literature review of prosthodontic outcomes.

Eur J Oral Implantol. 2017;10 Suppl 1:13-34.

Abstract

AIM:

To compare implant fixed complete dentures with implant overdentures relative to prosthodontic outcomes.

MATERIAL AND METHODS:

An electronic Medline (PubMed) with MeSH terms, and Cochrane library search was performed, focusing on studies that included implant fixed complete dentures and implant overdentures in the same study, with the results based on studies that included both types of prostheses.

RESULTS:

The following six categories of comparative studies were identified in the literature: 1) Implant and prosthesis survival; 2) Prosthesis maintenance/complications; 3) Bone changes; 4) Patient satisfaction and quality of life; 5) Cost-effectiveness; and 6) Masticatory performance. It was determined that both the fixed and removable treatments were associated with high implant survival rates. However, both types of prostheses were impacted by the need for post-placement mechanical maintenance or prosthetic complications. More maintenance/complications occurred with implant overdentures than with fixed complete dentures. Residual ridge resorption was greater with implant overdentures. Patient satisfaction was high with each prosthesis, with three studies revealing higher satisfaction with fixed complete dentures and five studies finding no difference. All but one study on cost-effectiveness indicated implant overdentures were more cost-effective. Based on two studies, it appears the masticatory performance of implant fixed complete dentures and implant overdentures is comparable.

CONCLUSIONS:

Multiple factors must be considered when determining whether an implant-fixed complete denture or implant overdentures are best suited for patients with completely edentulous jaws. Conflict-of-interest statement: The authors declare they have no conflicts of interest.

Accuracy of digital implant impressions with intraoral scanners. A systematic review.

Eur J Oral Implantol. 2017;10 Suppl 1:101-120.

Abstract

AIM:

The use of intraoral scanners (IOS) for making digital implant impressions is increasing. However, there is a lack of evidence on the accuracy of IOS compared with conventional techniques. Therefore, the aim of this systematic review was to collect evidence on the accuracy of digital implant impression techniques, as well as to identify the main factors influencing the accuracy outcomes.

MATERIALS AND METHODS:

Two reviewers searched electronic databases in November, 2016. Controlled vocabulary, free-text terms, and defined inclusion and exclusion criteria were used. Publications in English language evaluating the accuracy outcomes of digital implant impressions were identified. Pooled data were analysed qualitatively and pertinent data extracted.

RESULTS:

In total, 16 studies fulfilled the inclusion criteria: one in vivo and 15 in vitro studies. The clinical study concluded that angular and distance errors were too large to be acceptable clinically. Less accurate findings were reported by several in vitro studies as well. However, all in vitro studies investigating the accuracy of newer generation IOS indicated equal or even better results compared with the conventional techniques. Data related to the influence of distance and angulation between implants, depth of placement, type of scanner, scanning strategy, characteristics of scanbody and reference scanner, operator experience, etc were analysed and summarised. Linear deviations (means) of IOS used in in vitro studies ranged from 6 to 337 µm. Recent studies indicated small angle deviations (0.07-0.3°) with digital impressions. Some studies reported that digital implant impression accuracy was influenced by implant angulation, distance between the implants, implant placement depth and operator experience.

CONCLUSIONS:

According to the results of this systematic review and based on mainly in vitro studies, digital implant impressions offer a valid alternative to conventional impressions for single- and multi-unit implant-supported restorations. Further in vivo studies are needed to substantiate the use of currently available IOS, identify factors potentially affecting accuracy and define clinical indications for specific type of IOS. Data on Data on accuracy OF digital records, as well as accuracy of printed or milled models for implant-supported restorations, are of high relevance and are still lacking. Conflict-of-interest and funding statement: The authors state there is no conflict of interest.

Misfit of implant prostheses and its impact on clinical outcomes. Definition, assessment and a systematic review of the literature.

Eur J Oral Implantol. 2017;10 Suppl 1:121-138.

Abstract

BACKGROUND AND AIM:

Compromised fit between the contact surfaces of screw-retained implant-supported fixed dentures (IFDs) is thought to create uncontrolled strains in the prosthetic components and peri-implant tissues, thus evoking biological and technical complications such as bone loss, screw loosening, component fractures and, at worst, loss of implants or prostheses. The aim of this systematic review was to evaluate the impact of marginal misfit on the clinical outcomes of IFDs, and to elucidate definition and assessment methods for passive fit.

MATERIALS AND METHODS:

A systematic review of the literature was conducted with a PICO question: "For partially or complete edentulous subjects with screw-retained IFDs, does the marginal misfit at the implant-prosthesis interfaces have an impact on the clinical outcomes?". A literature search was performed electronically in PubMed (MEDLINE) with the help of Boolean operators to combine key words, and by hand search in relevant journals. English written in vivo studies published before August 31, 2016 that reported on both clinical outcome and related implant prosthesis misfit (gap, strains, torque) were selected using predetermined inclusion criteria.

RESULTS:

The initial search yielded 2626 records. After screening and a subsequent filtering process, five human and five animal studies were included in the descriptive analysis. The selected studies used different methods to assess misfit (linear distortion, vertical gap, strains, screw torque). While two human studies evaluated the biological response and technical complications prospectively over 6 and 12 months, the animal studies had an observation period < 12 weeks. Four human studies analysed retrospectively the 3 to 32 years' outcomes. Screw-related complications were observed, but biological sequelae could not be confirmed. Although the animal studies had different designs, bone adaptation and implant displacement was found in histological analyses. Due to the small number of studies and the heterogenic designs and misfit assessment methods, no meta-analysis of the data could be performed.

CONCLUSIONS:

The current literature provides insufficient evidence as to the effect of misfit at the prosthesis-implant interface on clinical outcomes of screw-retained implant-supported fixed dentures. Marginal gaps and static strains due to screw tightening were not found to have negative effects on initial osseointegration or peri-implant bone stability over time. Based on two clinical studies, the risk for technical screw-related complications was slightly higher. While the degree of tolerable misfit remains a matter of debate, the present data do not imply that clinicians neglect good fit, but aim to achieve the least misfit possible. Conflict of interest statement: The authors declare no conflict of interest. The review was conducted as part of the 2016 Foundation of Oral Rehabilitation Consensus Conference on "Prosthetic Protocols in Implant-based Oral Rehabilitation".
