全瓷高嵌体修复根管治疗后牙体缺损的临床效果分析

Analysis of Clinical Effect of All-Ceramic Onlay Restoration for Tooth Defects After Root Canal Therapy

目的:探讨全瓷高嵌体修复根管治疗后牙体缺损的临床效果。方法:选取2021年1月—2023年1月绥阳县人民医院收治的86例根管治疗后牙体缺损患者作为研究对象,按照随机数字表法分为两组,各43例。对照组行氧化锆全瓷冠修复,观察组行全瓷高嵌体修复。比较两组修复效果。结果:观察组修复体完整度、边缘密合度、咬合力与咀嚼效率高于对照组,菌斑指数、牙龈指数、龈沟出血指数、口腔生理功能、心理功能、行为影响、疼痛与不适评分以及不良事件总发生率低于对照组,差异有统计学意义(P<0.05)。结论:全瓷高嵌体修复根管治疗后牙体缺损的临床效果显著,可改善患者牙周状况、咀嚼功能与生活质量,减少不良事件。

Objective:To investigate the clinical effect of all-ceramic onlay restoration for tooth defects after root canal therapy.Methods:A total of 86 patients with tooth defects after root canal therapy who were admitted to the People's Hospital of Suiyang from January 2021 to January 2023 were selected as the study subjects.They were divided into two groups according to random number table method,with 43 cases in each group.The control group received zirconia all-ceramic crown restoration,and the observation group received all-ceramic onlay restoration.The restoration effect was compared between two groups.Results:The integrity and marginal fit of the prosthesis,bite force and masticatory efficiency in the observation group were higher than those in the control group,and the plaque index,gingival index,gingival sulcus bleeding index,oral physiological function,behavioral influence,psychological function,pain and discomfort scores,as well as the total incidence of adverse events in the observation group were lower than those in the control group,and the difference was statistically significant(P<0.05).Conclusion:All-ceramic onlay restoration has significant clinical effects on tooth defects after root canal therapy,and can improve periodontal condition,masticatory function and quality of life,and reduce adverse events.
