    Abstract:
    OBJECTIVE: To evaluate the long-term clinical outcome of delayed implant placements after maxillary sinus floor augmentation with autologous bone or Bio-Oss grafting. METHODS: Eighteen patients underwent maxillary sinus floor augmentation and delayed implant placements from January, 2002 to December, 2008. Bone grafting and sinus floor augmentation were performed in 21 sides of maxilla and 46 implants were placed 6 - 8 months later. Residual bone height was less than 4 mm. The cases were divided to 2 groups and different materials (autologous bone + Bio-Oss and Bio-Oss alone) were grafted relatively. The bone resorption was assessed by panoramic X-ray and the stability of the implant was reviewed postoperatively. RESULTS: The average follow-up time was 54 months. Only one implant was lost and the implant survival rate was 98%. X-ray showed that the bone resorption was observed in both groups. The absorption ratio of autologous bone + Bio-Oss group was 18.65% and that of the Bio-oss group was 1.93%. The difference was significantly different. CONCLUSIONS: The result of maxillary sinus floor augmentation with bone grafting was predictable. More bone absorption occurred in the Bio-Oss than in autologous bone + Bio-Oss.
