摘　　要：目的分析长期使用功能后牙区种植支持单冠修复并发症的相关影响因素。方法选取2011年2月—2016年2月在福建中医药大学附属人民医院口腔科接受后牙区种植支持单冠修复、使用功能>3年的460例患者(682颗种植修复体),对修复并发症进行观察记录,对种植治疗效果进行评估;选择Logistic回归分析修复并发症的相关影响因素。结果全部682颗种植体中,在种植7~12年后,种植体存留率为98.83%,修复成功率为85.04%,修复体存留率为85.92%。全部682颗种植体中,发生修复并发症102颗,修复并发症发生率为14.96%(102/682)。出现崩瓷52颗,发生率为7.62%(52/682)。粘结固位修复体503颗,其中出现脱粘结32颗,发生率为6.36%(32/503)。发生基台及螺丝松动26颗,发生率为3.81%(26/682)。多因素分析结果显示,发生绷瓷的独立危险因素为偏侧咀嚼、夜磨牙、常咬硬物(P<0.05);发生脱粘结的独立危险因素为磨牙牙位、偏侧咀嚼、夜磨牙、常咬硬物(P<0.05);发生基台及螺丝松动的独立危险因素为年龄≥55岁、偏侧咀嚼、夜磨牙、常咬硬物、种植体直径、角度基台(P<0.05)。结论长期使用功能的后牙区种植支持单冠的修复效果比较理想,但是需要及早发现和处理相关的修复并发症,以保证修复效果。此文的研究结果为长期使用功能的后牙区种植支持单冠的后期标准制定提供了借鉴内容。Objective To analyze the factors related to the complications of single crown supported by long-term functional implant in posterior teeth.Methods A total of 460 patients(682 implant restorations)who received implant supported single crown restoration in the posterior tooth area from February 2011 to February 2016 in the department of stomatology,the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine and whose using function was more than 3 years were selected to observe and record the repair complications and evaluate the effect of implant treatment.Logistic regression analysis was selected to analyze the relevant influencing factors of repair complications.Results Among all 682 implants,after 7-12 years of implantation,the implant retention rate was 98.83%,the repair success rate was 85.04%,and the repair retention rate was 85.92%.Out of all 682 implants,a total of 102 had repair complications,with a repair complication rate of 14.96%(102/682).A total of 52 porcelain fragments occurred,with an incidence rate of 7.62%(52/682).There are a total of 503 bonded retention restorations,of which 32 have experienced debonding,with an incidence rate of 6.36%(32/503).A total of 26 cases of pedestal and screw loosening occurred,with an incidence rate of 3.81%(26/682).The results of multivariate analysis showed that the independent risk factors for porcelain tension were unilateral chewing,night grinding,and frequent biting of hard objects(P<0.05).The independent risk factors for debonding include molar position,unilateral chewing,night grinding,and frequent biting of hard objects(P<0.05).The independent risk factors for abutment and screw loosening are age≥55 years old,unilateral chewing,night grinding,frequent biting of hard objects,implant diameter,and angle of abutment(P<0.05).Conclusion The long-term use of functional posterior dental implant support for single crown restoration is relatively ideal,but it is necessary to detect and handle related repair complications as soon as possible
