Abstract

BACKGROUND
Several bone grafting materials have been used in sinus augmentation procedures. Macroporous Biphasic Calcium Phosphate(MBCP(TM)) consists of the mixture of 60% HA and 40% beta-TCP. Therefore, it can provide good scaffold for the new bone to grow owing to HA, in the other hand, it can have bioactivity for bone remodeling owing to beta-TCP. The purpose of this study was to evaluate bone formation following maxillary sinus augmentation using MBCP(TM) by means of histologic analysis. MATERIAL AND METHOD: MBCP(TM) was placed as a primary bone substitute for maxillary sinus augmentation. Three patients were selected after evalaution of their medical dental examination. MBCP(TM) only, MBCP(TM) combined with Irradicated cancellous bone and MBCP(TM) combined with autogenous bone were used for each patient. After about eight months, bone biopsies were harvested for histologic evaluation and fixtures installed.
RESULTS
Eight months after surgery we observed new vital bone surrounding MBCP(TM) particle and the amount of new bone was about 30% even though there were discrepancies between specimens. This case report documents that MBCP(TM) when used as a grafting material for sinus floor augmentation whether combined other bone graft material or not, may lead to the predictable results for dental implants on posterior maxillary area with insufficient vertical height for fixture installation.
