上颌窦内提升同期种植的临床效果观察

Clinical Effects Observation of Implant-supported Rehabilitations with Maxillary Sinus Floor Elevation and Simultaneous Implant Placement

目的：观察上颌窦底内提升同期种植体植入的成功率及临床效果。方法：对2009年1月-2012年12月在无锡市第二人民医院口腔科收治的上颌后牙缺失、行上颌窦底内提升术并同期植入种植体的18例（共28颗种植体）患者的临床资料进行评估。随访1～4年,观察种植体稳定性、上颌窦底高度、上颌窦有无炎症及种植体周围牙槽骨情况。结果：18例患者共26颗种植体术中均无上颌窦穿孔,随访观察种植体均无松动、脱落,上颌窦无炎症发生,全景片示种植体与骨均形成良好骨结合,种植体周围垂直骨吸收均小于1.5 mm。结论：在选择合适病例的前提下,上颌窦内提升并同期种植体植入术能取得较好的临床效果。

Objective： To observe the clinical effects of implant-supported rehabilitations with maxillary sinus floor elevation and simultaneous implant placement.Method： Totally twenty eight implants were placed in eighteen patients immediately after maxillary sinus floor osteotomy elevation. Patients were followed up post-operation 12-48 months. The residual bone height, wether the sinus inflammation and the state of alveolar bone around the implant.Result： No sinus membrane perforation was observed intraoperation, no failure and satisfactory function of twenty eight implants in eighteen patients was observed within 12-48 months. X-ray showed good osseointegration in the lifting sites, the vertical resorption around the implants were less than 1.5 mm.Conclusion：With the strict indications, the satisfied clinic efficient can be acquired with osteotome sinus floor elevation and simultaneous implant placement.
