title: Could Calcified Triglyceride Bone Cement Be an Alternative Graft Material in Maxillary Sinus Augmentation?
abstract: The ideal graft material for maxillary sinus augmentation is still a matter of controversy and the search for a more appropriate bone substitute for use continues. The aim of this study was to evaluate bone formation as a sign of the regeneration following maxillary sinus augmentation in rabbits using 3 different biomaterials, one of which is a newly developed graft material; calcified triglyceride bone cement (CTBC).Twenty-one New Zealand rabbits were used and randomly divided into 3 groups. Bilateral maxillary sinus augmentation was carried out and autogenous bone (AB), bovine hydroxyapatite (BHA), and CTBC were administered. Maxillary sinuses were dissected after fourth and eighth weeks of the operation. The bone formation was evaluated by stereological and histopathological analysis and the data were analyzed statistically.When the volume of primary bone is compared, statistically significant differences were found among all groups at both of the fourth and eighth weeks. The highest value was obtained from AB applied group. In BHA and CTBC applied groups, active bone formation, osseointegration of graft materials were observed at both fourth and eighth weeks. In CTBC applied group, primary bone formation was only seen as linked to the continuation of parent sinus bony wall.The efficiency of primary bone formation of CTBC was found less than AB and BHA. Of the 3 graft materials tested, BHA is the strongest alternative to AB graft for maxillary sinus augmentation.
