Abstract： 目的探讨以种植套筒冠覆盖义齿修复无牙颌的临床效果.方法对北京大学口腔医学院·口腔医院口腔种植中心就诊的21例无牙颌患者,采用种植套筒冠覆盖义齿修复.共28件修复体,其中上颌全颌覆盖义齿13件,下颌全颌覆盖义齿15件.共植入种植体139枚,其中Camlog74枚,IMZ 28枚,Frialit-2 37枚.种植体修复基台切削后直接作为套筒冠内冠,套筒冠外冠分别采用金沉积技术和失蜡铸造技术加工.修复后平均追踪26.5个月(12～39个月).以临床检查和影像学检查评价修复效果.结果至最后一次复查,21例患者临床检查未见修复体松动、折断、损坏,修复体固位好、稳定,种植体周围软组织健康.19例患者曲面断层X线片显示种植体周围骨组织稳定,无吸收.仅2例在修复3年后发现少量骨吸收,约1 mm.修复后至最后一次复查未见种植体脱落.结论种植套筒冠覆盖义齿稳定,种植体周围骨组织稳定,可用于无牙颌修复.
