上颌窦外提升不植骨术的临床应用观察

The clinical observation of lateral sinus lift without grafts

目的：评价上颌窦外提升不植骨术在种植修复中临床应用效果。方法：2012年01月至2013年04月完成18例上颌窦外提升术,其中随机分为实验组：共10例患者不植骨并同期植入种植体12枚;对照组：共8例患者植骨并同期植入种植体8枚,临床随访6～14个月。临床观察指标：种植体稳定性及口内软组织检查结合X线。结果：18例患者中一例出现术中上颌窦粘膜穿孔,在随访期内,种植体稳定性良好,无种植体松动脱落,软组织健康,X线显示上颌窦内有新骨形成。结论：本组病例结果提示上颌窦外提升不植骨术短期临床效果令人满意。

Objective： To evaluate the clinical outcome of lateral sinus lift without grafts. Methods： 18 posterior partially edentulous patients with residual bone height between 3 ～5mm were chosen to receive the lateral sinus lift, Patients were randomly assigned into two groups. Trial group： 10 patients received12 implants using lateral sinus lift technique without grafts; Control group： 8 patients received 8 implants using lateral sinus lift technique with bone substitutes. All patients were followed regularly after the surgery up to 14 months. The stability of the implants, the condition of peri-implant tissues, the radio exam of the bone height were checked during the revisits. Results： During the study period all implants were stable, no inflammation of the sinus were found. The soft tissue around the implants were healthy, and the X ray showed some extent of endo-sinus bone gain. Conclusion： The short-term clinical result of lateral sinus lift without grafts was satisfying.
