Abstract

Background
Several bone grafting materials have been used in sinus augmentation procedures. Macroporous
Biphasic Calcium Phosphate(MBCPTM) consists of the mixture of 60% HA and 40% β-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 β-TCP. The purpose of this study was to evaluate bone
formation following maxillary sinus augmentation using MBCPTM by means of histologic analysis.
Material and Method
MBCPTM was placed as a primary bone substitute for maxillary sinus augmentation. Three patients
were selected after evalaution of their medical dental examination. MBCPTM only, MBCPTM combined
with Irradicated cancellous bone and MBCPTM 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 MBCPTM particle and the
amount of new bone was about 30% even though there were discrepancies between specimens. This
case report documents that MBCPTM 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.
