Abstract
Purpose: Previous clinical investigations of sinus floor augmentation have demonstrated repneumatization of grafted sinus. The aim of this study is to evaluate and compare the height changes of sinus floor after grafting with deprotenized bovine bone mineral (DBBM) and beta tricalcium phosphate (TCP).
Materials and methods: 34 sinuses in 28 patients were augmented with 100% DBBM or 100% TCP through lateral approaches. Sinusgraft height was measured before, immediately after, and 6 months after bone graft with panoramic radiography.
Result: After 6 months, the decreases of graft heights were 14.53% for DBBM group and 15.15% for TCP group. There was no statistically significant difference.
Discussion and Conclusion: Long-term stability of sinus-graft height represents an important factor for implant success. After the uses of DBBM and TCP for maxillary sinus floor augmentations, acceptable graft height maintenances were observed.
