Abstract
Objective To explore the effects of different bone materials on bone resorption and implant retention rates in maxillary sinus floor lifting.Methods A total of 48 patients with dentition defect to receive treatment in our department were selected.Panoramic tomography X-ray examination showed that the residual alveolar bone height at the maxillary posterior part ≤4 mm.All patients were treated with maxillary sinus floor lifting and delayed implantation of bone graft on the maxillary anterior lateral wall.These patients were divided into an xenogeneic bone group (n=28,treated with simple xenogeneic bone graft material),and a mixed group (n=20,treated with autogenous bone combined with xenogeneic bone graft material.The bone resorption rate and retention rate between the two groups after bone grafting were compared according to the results of the X-ray follow-up visit.results Both maxillary sinus floor lifting and delayed implantation were successfully conducted on 48 patients.During the two-year follow-up visit,the amount of bone graft in the two groups decreased to some extent,but the bone graft area(45.75±6.91)mm2 in the xenogeneic bone group at the end of the follow-up visit was greater than that (40.04±4.57) mm2 in the mixed group,and the bone resorption rate (1.99％) was lower than that(15.24％) in the mixed group(P ＜ 0.05).57 and 42 implants were respectively implanted into the xenogeneic bone group and the mixed group;the retention rate during the follow-up visit was 98.25％ and 97.62％ respectively,showing no significant difference (P ＞ 0.05).Conclusion The bone absorption rate of maxillary sinus floor lifting with xenogeneic bone graft material is lower than that of xenogeneic bone combined with autologous bone,but the two methods have no significant impacts on the retention of delayed implant.关键词
