上颌窦底内提升术不植骨同期植入种植体8例临床分析

Osteotome sinus floor elevation technique without grafting material:clinical analysis of eight cases

目的:探讨上颌窦底内提升术在不植骨的情况下同期植入种植体的临床效果。方法:收集2008—2011年杨思医院口腔科收治的8例上颌磨牙缺失、施行上颌窦底内提升术不植骨同期植入种植体患者的临床资料,统计进行修复时和修复完成6个月后种植体的存留率,分析人工骨移植在上颌窦内提升术中所起的作用。结果:8例上颌磨牙缺失患者在不植骨的情况下,进行上颌窦底内提升术同期植入XIVE种植体14颗,修复时有1颗种植体因未形成骨结合而取出,修复完成后6个月复诊时,无种植体脱落,种植体存留率达92.9%。结论:不植骨并上颌窦底内提升同期植入种植体,6个月内能获得较高的存留率,接近文献报道的植骨并上颌窦底内提升术中种植体的存留率。

PURPOSE： To study the clinical results of XIVE implants placed immediately after sinus floor elevation using osteotomes without bone grafting. METHODS： Totally 14 XIVE implants were placed in 8 patients immediately after sinus floor elevation using osteotomes without bone grafting. The survival rates of the implants during the prosthodontic process and six months after the crowns fabricated were recorded and analyzed. RESULTS： One implant was loosen and extracted during the prosthodontic process and no implant failed six months after the crowns were placed. The survival rate of the implants in this study was 92.9%. CONCLUSIONS： Implants placed immediately after sinus floor elevation using osteotomes without bone grafting could achieve higher survival rates,which is similar to the reported survival rates in dental implants with bone grafting.
