摘　　要：目的 :探讨全瓷高嵌体修复前磨牙缺损的近、远期疗效及对牙功能的影响。方法 :选择北京大学人民医院2017年1月—2018年1月收治的95颗经根管治疗后的前磨牙,随机分为对照组(n=47)和实验组(n=48)。对照组采用全冠修复,实验组采用全瓷高嵌体修复。比较2组患牙成功、存留、失败情况,比较修复体6、12、36个月美国公众健康服务标准(USPHS)评估情况及牙咬合功能。采用SPSS 19.0软件包对数据进行统计学分析。结果:实验组患牙修复成功率、存活率高于对照组,但差异无统计学意义(P>0.05);12个月时,2组修复体外形、边缘密合性、边缘着色、表面质地、继发龋、牙龈健康、邻接关系相比,差异无统计学意义(P>0.05);36个月时,2组修复体边缘密合性、边缘着色、表面质地相比,差异均无统计学意义(P>0.05),实验组外形、继发龋、牙龈健康、邻接关系情况显著优于对照组(P<0.05);6、12、36个月时,2组患者患侧咬合功能与对侧相比,差异无统计学意义(P>0.05)。结论:全瓷高嵌体修复前磨牙缺损成功率、存留率高,近、远期修复效果好,有利于改善患牙咬合功能。PURPOSE: To investigate the short-term and long-term effects of all-ceramic onlay on restoration of premolars and its influence on dental function. METHODS: Ninety-five premolars receiving root canal treatment in People’s Hospital of Peking University from January 2017 to January 2018 were enrolled, and randomly divided into two groups based on different repairing methods. Patients in the control group(n=47) received full crown restoration, while patients in the experimental group(n=48) received all-ceramic onlay restoration. The success, survival and failure rates of the teeth were compared. The United States Public Health Service(USPHS) and occlusal function of the prosthesis were compared 6,12 and 36 months after treatment. The data were processed using SPSS 19.0 software package. RESULTS: The success and survival rate of the experimental group were higher than those of the control group, but without significant difference(P >0.05). The morphology, marginal integrity, marginal coloration, surface texture, secondary caries, gingival health and proximal contacts showed no significant difference between the two groups 12 months after treatment(P>0.05). Thirty-six months after treatment, the marginal integrity, marginal coloration and surface texture showed no significant difference be-tween the two groups(P>0.05), while the morphology, secondary caries, gingival health and proximal contacts were significantly better in the experimental group than in the control group(P<0.05). The occlusal function between the affected side and contralateral side of both groups showed no significant difference 6, 12 and 36 months after treatment(P>0.05). CONCLUSIONS: All-ceramic onlay restoration of premolars has high success and survival rate, and good short-term and long-term restoration effect, which is beneficial to improve the occlusal function of the affected teeth.
