Clinicoradiographic Evaluation of Long-term Efficacy and Risk Factors Associated with Dental Implants used for Full Mouth Rehabilitation

BACKGROUND: Despite various complications and failure factors, newer implants are designed that allow placement in sub-optimal conditions to allow the operator to place implants at sites with low bone quality. These newer designs also allow improved stability with higher survival rates in the short term. AIMS: The present study was undertaken to evaluate long-term efficacy and risk factors associated with dental implant placement for full mouth rehabilitation. MATERIALS AND METHODS: In 24 subjects, 438 implants were placed. The data collected were surgical and were retrospectively analyzed. The data collected included medical history, local, patient satisfaction, marginal bone loss, and systemic risk factors affecting implant survival. Outcome variables assessed were peri-implantitis, implant success, and survival at the follow-up visit. The data were expressed in terms of percentage and number, and the results were derived. RESULTS: Peri-implantitis was seen in 31.05% (n = 136) of implants. 76.02% (n = 333) of implants were considered successful at recall. Concerning survival, compromised and satisfactory survival was shown by 10.04% (n = 44) and 2.96% (n = 13) of implants, respectively. 10.95% (n = 48) of implants were considered as failures. CONCLUSION: The present study concludes that good, long-term survival rates are associated with full mouth rehabilitation using dental implants.
