2种上颌窦提升术在牙种植中的应用

Clinical application of maxillary sinus lifting, bone graft and simultaneous placement of implant

目的:比较2种上颌窦提升术同期植入种植体的临床疗效。方法:采用2种上颌窦提升技术,对31例42颗垂直骨量不足的上颌后牙行上颌窦提升术及同期种植体植入术。术后1、3、6个月检查上颌窦及种植体骨结合情况。结果:无种植体松动、脱落及上颌窦炎发生,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。经6-36个月随访观察,临床效果良好。结论:掌握适应证和手术技巧,2种上颌窦提升术同期植入种植体的临床疗效均良好。

PURPOSE： To evaluate the results of two kinds of sinus lifting techniques with simultaneous implant placement. METHODS： 31 maxillary sinus underwent two kinds of sinus lifting techniques and simultaneously 42 implants placement. The sinuses were observed 1,3,6 months after the surgery. RESULTS： There were no implants loose or lost; X ray examination showed well osseointegration and no maxillary sinusitis. All the patients finished implant prosthesis in 6 months postoperatively.Through 6-36 months＇ follow-up,clinical results were satisfactory. CONCLUSION： With properly handling of indication and the operation skill, the results of two kinds of maxillary sinus lifting techniques with bone grafting and simultaneously implants placement are both satisfactory.
