Abstract
Purpose: The purpose of this study was to analyze the cumulative survival rate of dental implants installed with guided bone regeneration (GBR), and also elucidate the factors related with the survival of dental implants.
Material and Methods: This retrospective study was conducted on 148 dental implants installed in 76 patients by one specialist (Y.K.) at the Department of Periodontology and Implant Center, Seoul National University Dental Hospital from 2001 to 2010. The cumulative survival rates were obtained by the Kaplan-Meier method. The correlations between various factors and dental implant survival were analyzed by using the log-rank test and Cox proportional hazards model.
Results: Among 148 dental implants installed in 76 patients, 8 implants in 7 patients were lost and the cumulative survival rates up to 5-years and 10-years were 97% and 89%, respectively. Gender, smoking status and location of implant were significantly associated with the cumulative survival rate of implants (p < 0.05). Age, history of hypertension and diabetes were not significantly associated with the cumulative survival rate of implants (p > 0.05).
Conclusion: The dental implants installed with guided bone regeneration is predictable technique according to the results of cumulative survival rate over 10 years.
