目的：研究在上颌骨骨量不足情况下,采用非翻瓣不植骨法行上颌窦内提升的种植义齿临床效果。方法：收集2013年12月-2014年12月期间,在剩余牙槽骨高度（residual bone high,RBH）不足情况下,完成的30例不翻瓣不植骨的上颌窦内提升种植术...目的：研究在上颌骨骨量不足情况下,采用非翻瓣不植骨法行上颌窦内提升的种植义齿临床效果。方法：收集2013年12月-2014年12月期间,在剩余牙槽骨高度（residual bone high,RBH）不足情况下,完成的30例不翻瓣不植骨的上颌窦内提升种植术病例。随访6-12个月,平均（9.8±1.6）个月。全部病例均在术后6个月内完成上部义齿修复。观察术后种植体的稳定性、种植体周围软组织状况及种植体周围骨结合及骨量改变的情况。结果：30枚种植体中有2枚术中发现上颌窦粘膜穿通,同期放入生物膜,观察期内未出现上颌窦内炎症等并发症;在观察期内30枚种植体成功率100%。术后6个月上颌窦底种植体周围骨质增加高度平均（2.8±0.6）mm,种植体边缘骨吸收（1.3±0.4）mm。结论：在上颌骨牙槽突高度不足的情况下,非翻瓣不植骨法上颌窦内提升术是一种安全,有效的种植术式。展开更多
目的评价液压法上颌窦底提升术在上颌后牙区垂直骨量严重不足时的应用及临床效果。方法 31例上颌后牙缺失患者,共53个植入位点。选择剩余骨高度（residual bone height,RBH）小于4mm（1.12-4mm）的位点。采用OSSTEM CAS-KIT工具行上颌...目的评价液压法上颌窦底提升术在上颌后牙区垂直骨量严重不足时的应用及临床效果。方法 31例上颌后牙缺失患者,共53个植入位点。选择剩余骨高度（residual bone height,RBH）小于4mm（1.12-4mm）的位点。采用OSSTEM CAS-KIT工具行上颌窦底内提升术,同期植入种植体,随访9-30个月。结果 53个种植位点中仅1例1个位点在术中发生黏膜破裂而改行上颌窦外提升术种植,手术成功率为98.1%,其余52个种植位点均同期植入种植体,术后6个月CBCT检查种植体均形成良好骨结合,种植体存留率为100%,窦底骨量平均提升高度为7.43mm（6.22-12.47mm）。结论液压法上颌窦底提升术用于上颌窦底剩余牙槽嵴高度低于4毫米的病例并同期植入种植体时有较高的手术成功率,术后提升的骨高度保持良好,降低术中并发症的发生率、缩短手术时间、减轻患者术后反应。展开更多
