目的:评价上颌窦内提升并同期植入种植体在上颌后牙区缺失修复中的应用效果。方法:2007年～2011年共完成上颌窦内提升并同期植入种植体病例19例,男10例,女9例,年龄20～70岁,术前CT示:牙槽嵴至上颌窦底距离5～7 mm,行上颌窦提升术后共植入26枚种植体,采用骨粉作为填充材料,术后随访0.5～3年。结果:上颌窦提升3～5 mm,平均提升3.5 mm,术后未出现上颌窦炎症,无种植体松动脱落,X线检查,种植体与周围组织均形成良好的骨性结合,术后6个月完成义齿修复。结论:上颌窦内提升术创伤小,严格掌握适应症可降低上颌窦黏膜穿破风险。
OBJECTIVE: To evaluate the effect of maxillary sinus ascending and simultaneous implantation of implants in the repair of maxillary posterior teeth defects. Methods: From 2007 to 2011, 19 cases of maxillary sinus implantation and simultaneous implant implantation were performed, including 10 males and 9 females, aged from 20 to 70 years. Preoperative CT showed that the distance from alveolar ridge to maxillary sinus floor 5 ~ 7 mm, a total of 26 implants were implanted after maxillary sinus lift, bone meal was used as filling material, followed up for 0.5-3 years after operation. Results: The maxillary sinus was elevated 3 ~ 5 mm with an average increase of 3.5 mm. No maxillary sinus inflammation, no loosening of the implant, X-ray examination and good osseointegration of the implant with the surrounding tissue were found. Six Month to complete the denture repair. CONCLUSIONS: The maxillary sinus ascending trauma is small, and strict indications can reduce the risk of perforation of maxillary sinus mucosa.
