Abstract
Purpose: The purpose of this study was to evaluate 2 years cumulative survival rate of implants on augmented sinus area using MBCP, mixture of MBCP and ICB, and mixture of MBCP and autogenous bone by means of clinical and radiologic methods.
Materials and Methods: In a total of 37 patients, 41 maxillary sinuses were augmented and 89 implant fixtures were installed simultaneously or after a regular healing period. The patients were divided in 3 groups: MBCP only, MBCP combined with ICB, MBCP combined with autogenous bone. After delivery of prosthesis, along 2 years of observation period, all implants were evaluated clinically and radiologically. And the results were as follows.
Results: The results of this study were as follows. 1. A 2 year cumulative survival rate of implants placed with sinus augmentation procedure using MBCP was 97.75%. 2. Survival rate of implants using MBCP only was 97.62%, MBCP and ICB was 100%, MBCP and autogenous bone was 95%. There was no statistically significant difference between 3 groups. 3. Only 2 of 89 implants were lost before delivery of prosthesis, so it can be regarded as an early failure. And both were successfully restored by wider implants.
Conclusion: It can be suggested that MBCP may have predictable result when used as a grafting material of sinus floor augmentation whether combined with other graft(ICB, autogenous bone) or not. And the diameter, length, location of implants did not have a significant effect on 2 year cumulative survival rate.
