Systematic Review Prognosis of dental implants in patients with low bone density: A systematic review and meta-analysis
Statement of problem
Osteoporosis is a risk factor for implant success. Evidence for the prognosis of dental implants in patients with osteoporosis is still unclear.
Purpose
The purpose of this systematic review was to compare implant success in patients with low versus normal bone density and to evaluate special techniques used to enhance implant success in these patients.
Material and methods
Searches
were performed electronically in 4 databases (PubMed, LILACS, Cochrane,
and Grey Literature) through July 2017 and manually to identify studies
addressing the subject. Randomized and nonrandomized clinical trials
and cohort studies were included.
Results
Eleven
studies met the eligibility criteria, with a total of 1071
participants. Seven studies compared implant success in low and normal
bone density, and 4 compared implant success in special and conventional
techniques of implant placement. The risk of bias in the assessment of cohort studies was critical; of nonrandomized clinical trials, serious; and of randomized clinical trials, high. The meta-analysis
showed no significant difference between implant survival in patients
with low and normal bone density 5 years after implant placement.
Conclusions
Implant
survival in patients with low bone density seems to be feasible with
special precautions. Implant placement using special adopted techniques
might provide equivalent implant stability, survival, and marginal bone loss to normal bone. The quality of evidence is still unclear.
