摘要
目的:对下颌第一磨牙拔除后行种植修复的病例进行回顾性研究,探索重度牙周破坏(advanced periodon-tal defect,APD)对拔牙后种植手术方式的影响.方法:纳入下颌第一磨牙拔除后自然愈合3～12个月行种植手术的患者176例,共179个种植位点,进行回顾性分析,记录患者年龄、性别、缺牙时间以及拔牙时是否有APD.采用多因素Logistic回归,分析拔牙前APD是否是种植时行引导性骨再生(guided bone regeneration,GBR)的风险因素.结果:对年龄、性别、缺牙时间等因素校正后,结果显示,有APD的下颌第一磨牙,种植时行GBR的风险是无APD位点的4.738倍(95％可信区间:1.650～13.609,P＜0.05).结论:APD的下颌第一磨牙拔除后,种植手术时行GBR的可能性更大.
Abstract
Objective:To determine whether advanced periodontal defect(APD)was the risk factor of guided bone regeneration(GBR)in implant surgery of mandibular first molar.Methods:One-hundred and seventy-six patients with 179 implants placed in naturally healed mandibular first molars sites were included.The time interval between tooth extraction and implant surgery was 3-12 months.Age,sex,the time interval,and APD(yes or no)of extrac-ted teeth were recorded.The risk factors of GBR were assessed using Logistic regression.Results:Adjusting for age,sex,and the time interval,the risk of GBR for implant surgery was 4.738 times higher in mandibular first molars with APD than non-APD sites(95％CI:1.650-13.609,P＜0.05).Conclusion:APD increases the risk of GBR in implant surgery of mandibular first molar.
