摘要
目的:探讨上颌窦内提升术在上颌后牙区严重骨萎缩患者种植修复中的临床应用及疗效观察。方法:对2007～2008年上颌后牙区牙槽骨剩余高度3.2～7.5 mm(平均高度5.2 mm)的牙缺失患者共20例行上颌窦内提升术,同期植入种植体30枚。术后1、3、6、12、24个月复查行X线片及口腔CT扫描。结果:所有种植体均获得了较好的初始稳定性;未发生相关上颌窦并发症。种植修复经24个月的临床观察,30枚种植体均获得了良好的骨结合,种植修复取得了较好的临床效果,X线片及牙科CT扫描,种植体周围形成的新生骨组织稳定。结论:上颌窦内提升并同期牙种植术对于上颌后牙区牙槽骨高度严重不足病例能够减少种植手术创伤,缩短种植修复时间,取得较为满意的治疗效果。
Objective： To evaluate the clinical results of sinus floor elevation and dental implant in patients with severe alveloar bone adsorption. Method. Total 20 cases with dental defect and severe albeloar bone adsorption.Patients with less 5 mm height of residual bone received sinus floor elevation and implant with bone grafts while patients with above 5 mm height of residual bone received sinus floor elevation and implant without bone grafts.All patients was followed 24 months. Result： the elevated height was 3-7 mm. The cases gained good ossteointegration and received restoration after 4-6 months. With 24 months follow-up after implantation, the success rate was 100 %. Conclusion： Sinus floor elevation and simultaneous dental implant was successfully applied for patients with severe alveloar bone adsorption.
