Purpose: This research sought to determine the resorption rate of bone grafted to the maxillary sinus according to the grafted material’s type, patient’s age, systemic disease, implant size, site of implant placement, and residual ridge height.
Materials and Methods: This research targeted 24 patients who had immediate Osstem<SUP>®</SUP> implant (US Plus<SUP>®</SUP>) placement after bone graft. The panorama was taken before the surgery, after the surgery, and 6 months after the surgery. Vertical height change and resorption rate of the grafted bone were measured with the same X-rays and compared. The influence of the following factors on the grafted bone material’s resorption rate was evaluated: grafted material type, patient’s age, systemic disease, implant size, site of implant placement, and residual ridge height.
Results: Patients in their 40s had 34.0±21.1% resorption rate, which was significantly higher compared to the other age groups (P＜0.05). There was no significant relationship between systemic disease and grafted bone resorption. There was no significant relationship between implant size (diameter, length) and grafted bone resorption. There was no significant relationship between the site of implant placement and grafted bone resorption. The ramal bone-grafted site was significantly more resorbed than the ramal bone/Bio-Oss<SUP>®</SUP>-grafted site, maxillary tuberosity bone/Bio-Oss<SUP>®</SUP>-grafted site, and ramal bone/maxillary tuberosity bone/Bio-Oss<SUP>®</SUP>-grafted site (P＜0.05). There was no significant difference in the grafted bone resorption rate in the sinus between more than 4 mm and less than 4 mm residual ridge heights. After an average of 6 months, a second surgery was done; given an average follow-up of 1.9 years, the success rate and survival rate of the implant were 96.9% and 98.4%, respectively.
Conclusion: These results indicate that the bone resorption rate of grafted bone among patients in their 40s is higher compared to patients in their 50s and over, and that only autogenous bone (ramus) shows higher resorption rate than the mixed graft of autogenous bone and xenogenous graft (Bio-oss) after maxillary sinus graft.
