摘要： 目的:研究咬合面形态设计对种植体周组织健康状况的影响,为临床应用提供参考依据。方法:收集后牙区缺失行种植义齿修复的患者154人计203颗种植体,修复体咬合面设计为牙尖-卵圆窝形态,追踪观察2年内不同时段种植体周骨吸收、种植体周牙龈指数、出血指数、种植体周袋深度、咬合关系、邻接关系等变化情况,进行统计学分析。结果:在为期12~24个月的追踪观察中,种植体周骨吸收、种植体周袋深度、牙龈指数、出血指数、咬合关系在各时间段没有显著性差异,在负重12、24个月后种植体周骨吸收分别为(0.86±0.21) mm和(1.05±0.30) mm;种植体周袋深度分别为(1.83±0.87) mm和(2.06±0.59) mm,差异没有统计学意义。分别有4颗和10颗修复体与邻牙出现食物嵌塞。结论:种植义齿的特殊性决定其咬合设计有异于常规修复体,尖-卵圆窝设计对保护植体周组织健康起到决定性作用。

Abstract: Objective: To evaluate the relationship between occlusion design of implant-supported restorations and peri-implant tissues health. Methods: 203 implants were inserted into 154 patients with posterior teeth loss. The occlusal surfaces of implant-supported restorations were designed for cusp to circle sunken. Peri-implant bone loss, PD, GI, occlusal contact, and proximal contact were evaluated within 12 to 24 months follow-up. Results: In 12 to 24 months follow-up, the peri-implant bone loss was (0.86±0.21)mm and (1.05±0.30)mm, PD was (1.83±0.87)mm and (2.06±0.59)mm, respectively. There were no significant differences. There were 4 and 10 restorations with food impaction. GI was not significantly changed at different call back times. Conclusion: The occlusal surface of implant-supported restorations designed as cusp to circle sunken was useful to peri-implant tissues health.
