摘　　要：目的评价邻牙合面缺损的前磨牙残冠采用高嵌体,桩核冠修复后的临床疗效。方法收集2009-2011年在郑州人民医院口腔科就诊的邻牙合面缺损前磨牙残冠患者89名,共计103颗患牙。根据不同的修复方式分为三组,A组铸瓷高嵌体,B组纤维桩树脂核加全瓷冠,C组银钯合金桩核冠修复患牙。定期随访3年记录临床检查请况并对临床效果进行评价。结果 103颗前磨牙残冠修复后随访3年,随访到101颗,成功94颗(成功率93.1%),失败7颗。高嵌体修复组牙体折断1例,纤维桩树脂核修复组牙体颈部折断3例,银钯合金桩核修复组根折2例,根尖炎症1例。高嵌体修复成功率96.7%(29/30),纤维桩树脂核加全瓷冠修复成功率为91.9%(34/37),银钯合金桩核冠修复成功率为91.1%(31/34),三种修复方式比较差异无统计学意义(χ2=0.682,P>0.05)。结论前磨牙邻牙合(Ⅱ类)洞采用高嵌体,纤维桩树脂核全瓷冠及银钯合金桩核冠均可取得较好的临床修复效果,高嵌体更有利于保存余留牙体组织。Objective To evaluate the clinical effect of restoring premolar residual crown with onlay restoration or post core crown. Methods 89 patients, who suffering premolar residual crown, and then accept restoration in Dental clinic of Zhengzhou People＇s Hospital from 2009 to 2011, a total of 103 teeth, were collected in this study. According to the different ways of restoration, the patients were departed into three groups： A Group, castable ceramic onlay restoration, B Group, fiber post resin core with ceramic crown, C Group, silver palladium metal post core crown. The patients were followed up 3 years, and the clinical effect were examined and evaluated. Results Following up 3 years,101 teeth were followed and 94 teeth achieve successes （success rate 93.1%）. 7 cases were failure. 1 case in castable ceramic onlay restoration group was tooth fracture.3 cases in fiber post resin core with ceramic crown group were tooth neck fracture. 2 cases in silver palladium metal post core crown were root fracture. The success rate of the three groups were 96.7% （29/30） , 91.9% （34/37） and 91.1% （31/34） respectively, and there is no significant difference between groups （x^2=0.682,P〉0.05） . Conclusion Restored premolars meiso-occlusal cavity （ Class Ⅱ ） using three different methods, castable ceramic onlay restoration, fiber post resin core with ceramic crown and silver palladium metal post core crown, can achieve good clinical effect. Especially, onlay restoration is more advantage to protect the remaining tooth hard tissue.
