Angle Orthod. 2010 Jan;80(1):30-6.
Five years of sleep apnea treatment with a mandibular advancement device.

Martínez-Gomis J, Willaert E, Nogues L, Pascual M, Somoza M, Monasterio C.

a Associate Professor, Department of Prosthodontics, Faculty of Dentistry, University of Barcelona, Barcelona, Spain.

Abstract Objective: To determine the variation in prevalence of temporomandibular disorders (TMD), other side effects, and technical complications during 5 years of sleep apnea treatment with a mandibular advancement device. Materials and Methods: Forty patients diagnosed with obstructive sleep apnea received an adjustable appliance at 70% of the maximum protrusion. The protrusion was then progressively increased. TMD (diagnosed according to the Research Diagnostic Criteria for TMD), overjet, overbite, occlusal contacts, subjective side effects, and technical complications were recorded before and a mean of 14, 21, and 58 months after treatment and analyzed by the Wilcoxon test (P < .05). Results: Fifteen patients still used the oral appliance at the 5-year follow-up, and no significant variation in TMD prevalence was observed. Subjective side effects were common, and a significant reduction was found in overjet, overbite, and in the number of occlusal contacts. Furthermore, the patients made a mean of 2.5 unscheduled dental visits per year and a mean of 0.8 appliance repairs/relines per year by a dental technician. The most frequent unscheduled visits were needed during the first year and were a result of acrylic breakage on the lateral telescopic attachment, poor retention, and other adjustments to improve comfort. Conclusions: Five-year oral appliance treatment does not affect TMD prevalence but is associated with permanent occlusal changes in most sleep apnea patients during the first 2 years. Patients seek several unscheduled visits, mainly because of technical complications.

Orthodontic treatment of malocclusion improves impaired skillfulness of masticatory jaw movements.

Angle Orthod. 2009 Nov;79(6):1078-83.
Orthodontic treatment of malocclusion improves impaired skillfulness of masticatory jaw movements.

Tome W, Yashiro K, Takada K.

Abstract Objective: To investigate whether individuals with malocclusion show less skillfulness, as represented by kinematic parameters that characterize masticatory jaw movement, compared with those having normal occlusion and, if so, to examine whether more skilled movements are achieved after completion of orthodontic treatment. Materials and Methods: Lower incisor point movement in space during gum chewing was recorded, and the kinematic traits of such movement were compared among four subject groups: a Control Group (36 females with good occlusion), a Malocclusion Group (24 females with dental malocclusions), an Extraction Group (31 females who had received orthodontic treatment with premolar extraction) and a Nonextraction Group (27 females who had been treated orthodontically without tooth extraction). Before treatment, all subjects in the three experimental groups exhibited dental malocclusions and skeletal class I jaw-base relationship. Results: Compared with the Malocclusion Group, the lower normalized jerk-cost, the shorter phase durations, the more symmetric property of the velocity profile, and the smaller variance of lateral jaw-closing trajectories near the tooth intercuspation position were determined in the Extraction Group and the Nonextraction Group as well as in the Control Group. Conclusions: As measured by kinematic parameters such as normalized jerk-costs, velocity profile, and variance of movement trajectories near the endpoint of movement, dental malocclusions were associated with significantly lower skillfulness of masticatory jaw motion, whereas good occlusion and orthodontically improved occlusion (either with or without premolar extraction) were both associated with more skillful motion.

Brushing Dentures Might Be Best Cleaning Method

Health Behavior News Service

Brushing removable dentures with a paste product might be the best way to keep them clean, better than soaking in effervescent or enzyme cleaning solutions, suggests a new review of what little dental literature exists on the topic.

Keeping dentures clean and free from plaque buildup can help prevent oral infections and gingivitis; however, few clinical studies focus on the best way to clean partial or complete dentures.

This scarcity of studies on real-life patients was surprising, said lead review author Raphael Freitas de Souza, D.D.S. Most studies of denture cleaning methods happen in the laboratory. “We need clinical trials,” he said.

Dr. de Souza, with the Ribeirão Preto Dental School of the University of São Paulo in Brazil, and colleagues evaluated six randomized controlled studies. In some studies, the denture wearers were in institutions, while other studies involved patients at university dental clinics. Studies compared different denture cleaning methods to one another or to a placebo.

Reducing early childhood caries by 77 percent

Reducing early childhood caries by 77 percent
Training clinicians helps reduce rates of early childhood cavities

Researchers at Boston University School of Medicine (BUSM) have found that pediatricians provided with the proper communication, educational and information technology tools and training could reduce the rates of children developing early childhood caries (ECC) or cavities by 77 percent. This study appears in the October issue of the Journal Medical Care.

ECC, the most common chronic illness among children, can lead to serious complications if untreated, including abscesses requiring costly surgery. Infection and pain caused by ECC can also impair growth, weight gain and limit school attendance.

BUSM researchers provided pediatric clinicians with communication skills training to help them more effectively counsel parents and caregivers to reduce children's ECC risk. Pediatricians as well as clinical nurses participated in a one hour study training session, and they were also provided with educational brochures to give to parents. The electronic medical record was also adapted to prompt clinicians to remember to counsel. After the educational program, a simultaneous recruitment of children affected with ECC was conducted at a comparison site, where the clinicians did not receive training.

Parents and caregivers of children aged six months to five years were asked to participate in a clinical exam and interview that consisted of a series of questions inquiring about the parent or caregiver's discussion with the child's doctor or nurse. This interview assessed the degree the clinician covered the topics on which they had been trained to counsel regarding ECC risk reduction. This process was repeated approximately one year later.

The findings show that providers at the intervention site had greater knowledge and conducted more counseling, and patients at that site had significantly reduced odds of developing ECC over time. "Pediatric clinicians at Boston Medical Center are committed to children's oral health, and to addressing the deficit in clinical preparation to help prevent ECC," explained lead author, Nancy R. Kressin, PhD, an associate professor of General Internal Medicine at Boston University School of Medicine. "We developed and implemented a multi-faceted pediatric practice based intervention where children especially vulnerable to ECC received enhanced care to prevent this disease from occurring or reoccurring, and it had marked effects on reducing children's rates of developing ECC" said Kressin.

This study was funded by the National Institutes of Health the National Institute of Dental and Craniofacial Research.

The cariogenic dental biofilm: good, bad or just something to control?

Brazilian Oral Research
Braz. oral res. vol.23 supl.1 São Paulo 2009


This paper discusses the role of dental biofilm and adjunctive therapies in the management of dental caries. Dental biofilm is a site of bacterial proliferation and growth, in addition to being a location of acid production. It also serves as a reservoir for calcium exchange between the tooth and saliva. The salivary pellicle, a protein-rich biofilm layer, regulates the reaction between tooth surface, saliva and erosive acids. The protective effects of this pellicle on enamel are well established. However, understanding the effects of the pellicle/biofilm interaction in protecting dentin from erosive conditions requires further research. Saliva interacts with the biofilm, and is important in reducing the cariogenic effects of dental plaque as acidogenic bacteria consume fermentable carbohydrates producing acids that may result in tooth demineralization. Adequate supplies of healthy saliva can provide ingredients for successful remineralization. Strategies for managing the cariogenic biofilm are discussed with emphasis on the effectiveness of over-the-counter (OTC) products. However, since many toothpaste components have been altered recently, new clinical trials may be required for true validation of product effectiveness. A new generation of calcium-based remineralizing technologies may offer the ability to reverse the effects of demineralization. Nevertheless, remineralization is a microscopic subsurface phenomenon, and it will not macroscopically replace tooth structure lost in a cavitated lesion. Optimal management of cavitations requires early detection. This, coupled with advances in adhesive restorative materials and microsurgical technique, will allow the tooth to be restored with minimal destruction to nearby healthy tissue.

Comparison of intraoral radiography and limited cone beam computed tomography for the assessment of root-fractured permanent teeth

Dental Traumatology
Published Online: 14 Oct 2009
Michael M. Bornstein, Andrea B. Wölner-Hanssen, Pedram Sendi, Thomas von Arx

Abstract – Aim: To compare intraoral occlusal (OC) and periapical (PA) radiographs vs. limited cone beam computed tomography (CBCT) in diagnosing root-fractured permanent teeth. Material and methods: In 38 patients (mean age 24 years, range 8–52 years) with 44 permanent teeth with horizontal root fractures, intraoral radiographs (PA and OC) and limited CBCT were used to evaluate the location (apical, middle, cervical third of the root) and angulation of the fracture line. Furthermore, the conventional radiographs and CBCT images were compared for concordance of fracture location. Results: In the PA and OC radiographs, 28 fractures (63.6%) were located in the middle third of the root, 11 (25.0%) in the apical third and 5 (11.4%) in the cervical third. The PA/OC radiographs and the sagittal CBCT images (facial aspect) yielded the same level of root fracture in 70.5% of cases (31 teeth; 95% CI: 54.1–82.7%). The PA/OC radiographs and sagittal CBCT images (palatal aspect) showed the same level of root fracture in 31.8% of cases. There was a statistically significant association between the angle at which the root fracture line intersected the axis of the tooth and the level of root fracture in the facial aspect of the sagittal CBCT images. Conclusions: The diagnosis of the location and angulation of root fractures based on limited CBCT imaging differs significantly from diagnostic procedures based on intraoral radiographs (PA/OC) alone. The clinical significance for treatment strategies and for the prognosis of root-fractured teeth has to be addressed in future studies.

Madilyn- The girl with a killer toothach

A very eerie tale

Teeth And Gums Also Benefit From The Healing Power Of Aloe Vera

The aloe vera plant has a long history of healing power. Its ability to heal burns and cuts and soothe pain has been documented as far back as the 10th century. Legend has it that Cleopatra used aloe vera to keep her skin soft. The modern use of aloe vera was first recognized the 1930s to heal radiation burns. Since then, it has been a common ingredient in ointments that heal sunburn, minor cuts, skin irritation, and many other ailments. Recently, aloe vera has gained some popularity as an active ingredient in tooth gel. Similar to its use on skin, the aloe vera in tooth gels is used to cleanse and soothe teeth and gums, and is as effective as toothpaste to fight cavities, according to the May/June 2009 issue of General Dentistry, the Academy of General Dentistry's (AGD) clinical, peer-reviewed journal.

Aloe vera tooth gel is intended to perform the same function as toothpaste, which is to eliminate pathogenic oral microflora - disease-causing bacteria -in the mouth. The ability of aloe vera tooth gel to successfully perform that function has been a point of contention for some dental professionals. However, research presented in General Dentistry may alleviate that concern. The study compared the germ-fighting ability of an aloe vera tooth gel to two commercially popular toothpastes and revealed that the aloe vera tooth gel was just as effective, and in some cases more effective, than the commercial brands at controlling cavity-causing organisms.

Aloe latex contains anthraquinones, which are chemical compounds that are used in healing and arresting pain because they are anti-inflammatory in nature. But, because aloe vera tooth gel tends to be less harsh on teeth, as it does not contain the abrasive elements typically found in commercial toothpaste, it is a great alternative for people with sensitive teeth or gums. But buyers must beware. Not all aloe vera tooth gel contains the proper form of aloe vera. Products must contain the stabilized gel that is located in the center of the aloe vera plant in order to be effective. Products must also adhere to certain manufacturing standards. Dilip George, MDS, co-author of the study, explains that aloe "must not be treated with excessive heat or filtered during the manufacturing process, as this destroys or reduces the effects of certain essential compounds, such as enzymes and polysaccharides." Dr. George suggests that consumers consult non-profit associations such as the International Aloe Science Council to see what products have received the organization's seal of quality.

Although there are more than 300 species of the plant, only a few have been used for medicinal purposes. "Thankfully, consumers with sensitive teeth or gums have a number of choices when it comes to their oral health, and aloe vera is one of them," says AGD spokesperson Eric Shapria, MS, DDS, MAGD, MA. "If they are interested in a more alternative approach to oral hygiene, they should speak with their dentist to ensure that it meets the standards of organized dentistry, too."

Vioguard Self-Sanitizing Keyboard

Only issue is the $800 price tag!

TORONTO--(BUSINESS WIRE)--Vioguard LLC,, is introducing the world’s first self-sanitizing computer keyboard to kill MRSA and other healthcare-associated infections (HAIs) at the American Association of Oral and Maxillofacial Surgeons (AAOMS) 91st annual meeting, October 12-17 in Toronto. The event marks the first availability of the innovative keyboard for medical market uses and consumers in Canada.

Members of Vioguard’s management team will be available at booth #2334 during the meeting.

Harnessing the power and properties of ultraviolet light, Vioguard’s proprietary UVKB50 self-sanitizing keyboard is being introduced at a time when healthcare-associated infections (HAIs), including MRSA, strike an estimated 250,000 hospital patients in Canada each year. These “superbugs” kill an estimated 8,000 to 12,000 patients in Canada each year, according to 2008 statistics from Canadian Foundation for Infectious Diseases (CFID).

Ultraviolet light is known to be affective against harmful microorganisms such as H1N1 flu, MRSA and molds. Based on independent laboratory testing, the ultraviolet light generated by the unit’s two powerful 25-watt germicidal fluorescent lamps killed more than 99.99% of harmful bacteria and viruses, including MRSA and flu, in less than 90 seconds.

Priced at $899 US, it is currently available in Canada through For additional sales information call toll free at 866-910-0471 or email

Vioguard’s product has the look and feel of a standard notebook keyboard, and requires no software or special hardware to function. On a user-triggered or pre-determined basis, the Vioguard keyboard automatically retracts into its own clean, “light tight” enclosure and safely floods the keyboard with ultraviolet light to disinfect keyboard surfaces.

With widespread use of electronic medical records in Canada and elsewhere, computer keyboards have emerged as one of the prime focal points of contamination in dental offices and medical environments. Manual cleaning is currently the most common method used to disinfect keyboards. To be effective, keyboards should be wiped down repeatedly throughout the day--which is often difficult, impractical and labour-intensive.

Developed by former Microsoft Hardware veterans and their business partners, the self-sanitizing keyboard is the first product introduced by Bothell, Washington-based Vioguard.

“The spread of MRSA and other HAIs, not to mention flu, in Canada and elsewhere is a complex problem that's being tackled each day. We believe Vioguard is offering a new and effective tool in this fight,” said Vioguard’s Chief Technical Officer Craig Ranta, a former Microsoft Hardware engineering director.

The keyboard is now available for use by medical-oriented customers and consumers in Canada. In the United States, it is currently designated as an investigational device, limited by Federal (or United States) law to investigational use pending U.S. Food & Drug Administration clearance. FDA clearance is anticipated in the first quarter of 2010.

How it works

Since the early 20th century, ultraviolet germicidal irradiation has been studied and used to disinfect Microbes uniquely vulnerable to the effects of UV light at specific wavelengths that contain just the right amount of energy to break down organic molecular bonds. Viruses such as flu and MRSA are particularly impacted by UV light.

The key to the effectiveness of the product is not only the UV technology but specific and proprietary features, including:

* Automatic
o Disinfects the keyboard after each use. The user no longer has to manually wipe down the keyboard to disinfect it.
* Easy to use
o No flat, hard to use keyboard or keyboard cover. The keyboard features a high quality laptop style keyset and an advanced state of the art multi-touch track pad.
* Easy to install
o The keyboard unit is designed as a simple “plug-and-play” tool that works without the need of additional software.
* Reliable
o Self monitoring to ensure consistent UV exposure every time and extensive lifecycle testing for robustness.

“Our keyboard was designed to be durable, efficient and user-friendly where computer keyboards are shared,” said John Sharps, Vioguard’s Vice President of Development and Manufacturing who previously oversaw development and manufacturing of Microsoft Hardware products. “By presenting a disinfected keyboard to each user, our goal is to dramatically reduce the spread of MRSA, flu and other viruses and bacteria in shared computer environments.”

Survey Shows Americans are Unprepared for Dental Emergencies

New York, NY (October 9, 2009) Although 72 percent of Americans have fillings, caps or crowns and one in six had a dental emergency during the past 12 months, most are not prepared to deal with a dental emergency, according to a recent survey conducted by Majestic Drug Company, a leading provider of oral care products.

Interestingly, in the national survey of 1,000 Americans, those with a lower income (less then $35,000) were more likely to have had a dental emergency in the past 12 months (vs. 14 percent of those who make $100,000 or more).

Of those who had a dental emergency, 23 percent involved a loose crown or cap, 10 percent involved a lost filling, while 72 percent said their dental emergency involved something else.

Among those who had a dental emergency involving a loose crown/cap or a lost filling, 67 percent immediately went to a dentist, and 14 percent looked for a temporary solution to purchase, while 19 percent did nothing at the time.

“You keep medical supplies on hand for cuts and bruises, but what about your teeth? It’s important to be prepared for a dental emergency in case one happens, especially if the emergency occurs on a weekend when your dentist just isn’t available or you are on the road and cannot seek immediate dental care,” according to Brian Gold, D.D.S., who practices in Monticello, NY.

Dental emergencies can range from a dislodged cap/crown or lost filling to a knocked out tooth to pain or a cracked denture. Majestic Drug Company explains some common dental emergencies and suggestions for treatment.

· Knocked out tooth. If a permanent tooth is dislodged from the socket, try gently replacing it into the tooth socket. Do not scrub the tooth clean—you can damage the fibers needed for reattachment. If that doesn’t work, place the tooth in a glass of milk to keep it moist. Get to a dentist immediately.

· Mouth pain. A throbbing pain from a toothache may indicate an infection and a dentist should be consulted as soon as possible. Tooth sensitivity can be combated by the use of desensitizing toothpaste such as Sensodyne. Irritation from mouth sores can be alleviated by the use of specialized oral pain relief products such as Orajel.

· Lost filling. Rinse out the cavity with warm water. Apply a temporary filling product such as Dentemp® O.S. which can be made into a ball and pressed firmly into the cavity.

· Cracked or broken denture. According to Dr. Gold, all denture wearers should have a spare pair to use until the other is repaired. If not, it is good to keep on hand an emergency denture repair kit such as D.O.C. Emergency Denture Repair Kit, available at your local pharmacy.

· Dislodged cap/crown. Apply a temporary dental holding product such as Dentemp® O.S. and gently replace the cap onto the tooth. Make sure you get a proper fit.

· Irritation from Braces. Sharp wires can be coated with special dental wax available at your local pharmacy.

Remember, temporary dental solutions are just that—they are temporary. Make sure to seek professional assistance from your dentist as soon as possible.

ClearCorrect, Inc. Doubles the Size of its Houston Headquarters
Due to Increased Demand for its Transparent Orthodontic Aligners

Houston, TX – September 29, 2009 – ClearCorrect, Inc. recently completed a major expansion of its corporate headquarters due to the increased demand for its FDA-cleared transparent orthodontic aligners, commonly known as clear braces or invisible braces.

“We knew earlier this year that we needed to expand due to the increasing number of orthodontists and general dentists making the switch to ClearCorrect™ due to our affordability and as we do not have a minimum submission policy ,” said ClearCorrect CEO and prominent Houston cosmetic dentist, Dr. Willis Pumphrey.

The company was able to maintain its original address at 5200 Mitchelldale Street by acquiring adjacent space when it became available. “This will ensure the seamless expansion and integration of multiple departments, including manufacturing, telesales, customer support, marketing, and shipping. As soon as adjacent space became available, we grabbed it. We doubled our overall size, yet tripled our manufacturing footage,” Pumphrey commented.

With the additional space, Pumphrey estimates that ClearCorrect will be able to increase the production of its transparent orthodontic aligners by 600% and increase its staff across all departments by 30%. “We’ve already increased our staff by 20% in the last six months,“ he explained. “It was getting a bit tight.”

The company’s exponential growth continues to be fueled by it focus on educating the profession, rather than the consumer, in an effort to build relationships with orthodontists and general dentists, who will in turn recommend the advantages of ClearCorrect to their patients.

Sonicare FlexCare+ Motivates Patients for Better At-Home Care

Stamford, Connecticut (October 2, 2009) – What motivates your patients to maintain a good oral health care regimen at home? For some, it may be the promise of a whiter smile; for others it’s staying free of cavities. As a dental professional, your goal is to encourage those healthy habits, yet inconsistent at-home oral care and gum disease remain common patient problems. Philips Sonicare, the number one dental professional-recommended power toothbrush brand, has launched FlexCare+, its most advanced toothbrush yet. FlexCare+ is specifically designed to motivate patients to achieve consistent oral homecare for improved gum health.

“As a dental professional, I know that patients often need extra motivation to maintain consistent oral care regimes,” said Dr. Hal Crossley, D.D.S., Ph.D., Professor Emeritus at the University of Maryland Dental School. “The new Sonicare FlexCare+ has been proven to encourage patients to brush longer and more thoroughly at home for improved gum health, with the superior plaque biofilm removal that Sonicare has always delivered.”

With advanced features including a new Gum Care mode that provides two minutes of overall cleaning followed by one minute of gentle cleaning to focus extra effort on trouble spots along the gumline, FlexCare+ is clinically proven to improve gingival health in only two weeks. FlexCare+ also helps prevent gum recession, reduces bleeding sites by 71 percent in four weeks, reduces gum inflammation and even reduces gingivitis in smokers, a population at high risk for periodontal disease.

FlexCare+ motivates patients by providing a positive brushing experience that they can feel and see, including an invigorating sensation, clean-feeling teeth, excellent stain removal and less handle vibration. In clinical studies patients brushed significantly longer with FlexCare+ in Gum Care mode than with either a manual toothbrush or Oral-B® Triumph with SmartGuide.

“We’ve updated our successful and effective FlexCare with unique features to develop the most advanced Sonicare ever,” said Dr. Joerg Strate, Vice President, Philips Oral Healthcare, Clinical & Scientific Affairs. “FlexCare+ is the next evolution in improving patient motivation to help extend professional dental care to consistent at-home care in order to achieve a lifetime of better oral health.”

FlexCare+ continues to offer Sonicare’s patented sonic technology, five power modes and ProResult® brush heads to deliver exceptional results. In fact, FlexCare+ removes significantly more plaque than Oral-B® Triumph or a manual toothbrush both overall and in hard-to-reach places. Additionally, the integrated UV Sanitizer removes up to 99 percent of selected bacteria found on brush heads.

The Philips Sonicare brand is a leader in oral health care, and is backed by more than 175 publications and abstracts representing clinical and laboratory studies conducted at more than 50 universities and research institutes worldwide. Philips Sonicare power toothbrushes are proven to promote and improve oral health, from reducing plaque to improving overall gum health. They also have demonstrated the ability to increase patient compliance by promoting a consistent oral health and hygiene regimen between dental visits. Philips Sonicare is the number-one power toothbrush brand recommended by U.S. dental professionals for adults.

The suggested retail price for Philips Sonicare FlexCare+ is $189.99, and it will be available in October. FlexCare+ will be carried at retail outlets nationwide including drug, department and specialty stores, mass merchandisers and select dental offices. For more location information, visit

Align Technology, Inc. Announces Updates to Invisalign(R) Proficiency Requirements

Here is the latest press release from Align.

SANTA CLARA, Calif., Sept. 30, 2009 (GLOBE NEWSWIRE) -- Align Technology, Inc. (Nasdaq: ALGN) today announced updates to the Invisalign Proficiency Requirements, including a new designation for doctors who meet the annual requirements and an additional qualification period in 2010. The Invisalign Proficiency Requirements were launched June 1 to help ensure a baseline of Invisalign product experience and knowledge through minimum annual case and continuing education (CE) goals. To maintain active provider status, doctors must achieve at least ten shipped cases and ten hours of Invisalign-specific CE each year.

"We're only four months into the program and I'm very pleased with the progress we've seen to date -- key metrics, including Invisalign CE course participation, are up significantly and doctors are working with their Invisalign representatives to meet or surpass the minimum case and CE requirements by year-end," said Dan Ellis, Align's vice president, North American sales. "We want to do everything we can to help doctors achieve success, whether it's recognizing their commitment to Invisalign proficiency, or by helping increase their confidence in Invisalign products and treatment with new and improved features."

As part of the Invisalign Proficiency Requirements, Align has developed new ways to support doctors through this significant change, including a program to recognize doctors who achieve the annual proficiency requirements by year end. Doctors who meet the proficiency requirements of ten shipped cases and ten Invisalign CE hours by the end of 2009 will benefit from a new addition to Align's consumer marketing programs, one that encourages prospective patients to seek out "Invisalign Preferred Providers." Starting in January 2010, this new Invisalign Preferred designation will be highlighted on the Invisalign web site and in television ads as a way to recognize doctors' commitment to continued proficiency with Invisalign. The Invisalign Preferred designation will then be awarded on an annual basis to doctors who meet the proficiency requirements for a given year.

For doctors who are unable to meet the proficiency requirements this year, but demonstrate a desire to continue using Invisalign, Align will offer a one-time, additional six month qualification period that will enable doctors to secure their Invisalign provider status for 2010. Many of these doctors lack confidence with certain Invisalign techniques or with how widely Invisalign can be used in their practices. Recently-announced new and improved features in all Invisalign products may give doctors greater confidence in Invisalign and address perceived limitations of Invisalign treatment, especially among doctors who have not used the product extensively in recent years. The new features, which will be available in mid-October, are designed to deliver better results across more clinical situations, particularly with extrusions, rotations, and root movements. The additional six month qualification period will give doctors an opportunity to realize the value of these product improvements.

The additional six month qualification period stipulates that:
- Doctors who do not meet the proficiency requirements for 2009 but
have at least one shipped case and at least one Invisalign CE hour
at the end of this year will be allowed to maintain their active
provider status through June 30, 2010.
- Doctors who qualify for the additional six month qualification
period can secure their provider status for the second half of 2010
by meeting half of the annual proficiency requirements (at least
five shipped cases and five Invisalign CE hours) between January 1
and June 30, 2010.
- Doctors will still be responsible for meeting the total annual
requirements of at least ten shipped cases and ten Invisalign CE
hours by the end of 2010 to qualify as providers for the following

Doctors with zero shipped cases or zero Invisalign CE hours at the end of 2009 will not be eligible for the additional qualification period. They will be able to continue treating in-progress cases but will not be able to submit new Invisalign cases or use Invisalign branding or marketing resources.

Align does not expect the Invisalign Proficiency Requirements to have a material impact on the Company's fiscal year 2009 financial results. More information on the Invisalign Proficiency Program and the additional qualification period are available at
