经牙槽嵴顶上颌窦提升非植骨伴同期种植疗效观察

Clinical observation of implant supported rehabilitations with osteotome sinus floor elevation without bonegrafting and simultaneous implant placement

目的：探讨上颌后牙区种植时，经牙槽嵴顶的上颌窦底提升术（以下简称上颌窦内提升术）非植骨同期植入种植体修复上颌后牙缺失的临床疗效。方法：选择2013年1月-2014年1月来笔者科室行种植牙手术的24例接受上颌窦内提升非植骨术患者，内提升高度2～4mm,平均高度3.2mm，同期植入种植体，共植入种植体30颗，随访观察。结果：一期手术半年后，经X线检查种植体与周围组织形成良好的骨性结合，常规行种植修复，经两年观察种植体无不良反应，行使功能良好。结论：上颌窦内提升手术创伤小，在严格选择手术适应证的情况下，对垂直骨高度不足的上颌后牙区牙齿缺失，上颌窦内提升后非植骨同期植入种植体也能获得良好的种植骨结合效果。

Objective To investigate the clinical results of implant-supported rehabilitations with osteotome sinus floor elevation without bonegrafting and simultaneous implant placement. Methods A total of 24 patients were recruited from January 2013 to anuary 2014.With the traditional osteotomy elevation of maxillary sinus floor to 28 implants without bone grafting. Patients were followed up postoperation. Results After 6 months,X-ray showed good osseointegration in the lifting sites.After 2 years,all the implants were successfully infunct. Conclusion With the strict indications,the satisfied clinic efficient can be acquired with osteotome sinus floor elevation without bonegrafting and simultaneous implant placement.
