Abstract：AIM:To investigate the effects of maxillary sinus elevation with bone graft in the treatment of the rear vertical bone deficiency in maxillary edentulous area. METHODS:40 patients underwent maxillary sinus ele-vation were included,20 were treated with bone graft and 20 without. The patients were followed up at 6,12,24 and 36 months after operation.Clinical and radiographic examinations were performed to evaluate the rate of implant retention, marginal bone resorption and new bone formation. The effects were compared between the 2 groups. RESULTS: The cumulative implant retention rate of the 2 groups was 100% 3 years after operation.The average marginal bone resorp-tion at 36 months after operation was(1.08 ± 0.77)mm in bone graft group and(1.06+0.10)mm in non-bone graft group(P>0.05),there was no significant difference between the 2 groups in each follow-up visit (P>0.05).36 months after operation,the new bone formation in bone graft group and non-bone graft group was (3.01 ± 0.83)mm and (2.76 ± 0.68)mm respectively (P>0.05). CONCLUSION: There is no significant difference of long-term clinical effect of maxillary sinus elevation with bone graft compared with that without bone graft.
