上颌窦内提升不植骨同期种植术——3年临床回顾性研究
|
Abstract:
摘要 目的:评价上颌窦内提升不植骨同期牙种植术的临床效果。方法:收集38例上颌窦区域牙缺失患者,采用上颌窦内提升不植骨同期牙种植手术方式,共植入58颗种植体。在植入后6个月、1年和3年随访,统计种植体的成功率以及拍摄全景片测量上颌窦成骨的高度。结果:1年时,1颗种植体未形成骨结合脱落。3年时,另1颗种植体出现松动取出。其余56颗种植体正常行使功能,3年成功率96.6%。受植区平均牙槽骨高度为(5.8±0.2) mm,术后上颌窦内提升高度为(5.1±0.3)mm。上颌窦内种植体周围见新骨形成,6个月平均成骨2.4 mm,1年平均成骨2.8 mm,3年与1年成骨无明显变化。结论:上颌窦内提升不植骨同期牙种植手术方式是可行的,上颌窦黏膜具有潜在的成骨能力
