摘　　要：目的:评估短种植体(≤6 mm)在萎缩后牙区的长期临床疗效。方法:选取2009年1月~2012年1月南昌大学第四附属医院口腔科接受种植治疗的患者17例,共植入33枚Bicon植体(植体长度≤6 mm),观察期60~84个月不等,观察并记录边缘骨吸收量、种植体存留率及并发症。结果:在观察期内,33枚植体有1枚脱落,种植体存留率为97.0%,种植体修复完成60~84个月内种植体近远中骨吸收水平分别为(-0.74±0.05)mm、(0.05±0.07)mm,种植体近、远中边缘骨高度与修复后即刻比较差异均无统计学意义(P>0.05)。结论:在5~7年观察期内,短种植体(≤6 mm)应用于骨量不足的萎缩后牙区,其存留率及骨吸收水平与常规种植体无差异,可获得良好的中远期疗效。Objective:To evaluate the long-term clinical efficacy of short implants(≤6 mm)in the posterior teeth.Methods:From January 2009 to January 2012,17 patients in the Department of Stomatology,the Fourth Affiliated Hospital of Nanchang University were implanted with 33 Bicon implants(implant length≤6 mm).The observation period was 60-84 months.The marginal bone resorption,implant retention rate,and complications were recorded.Results:During the observation period,one of 33 implants fell off,the implant retention rate was 97.0%,and the bone resorption levels of the implants in the near and far of the implant were(-0.74±0.05)mm and(0.05±0.07)mm within 60 to 84 months after the restoration was completed.There was no significant difference in the bone height at the proximal and distal edges of the implant before and immediately after restoration(P>0.05).Conclusion:In the observation period of 5-7 years,the short implants(≤6 mm)are applied to the posterior teeth area with insufficient bone mass,and their survival rates and bone resorption levels are not different from those of conventional implants,and good long-term effects can be obtained.
