摘要
目的:探讨二氧化锆全瓷冠修复成人前牙轻度错的临床疗效。方法:选取某院共76例前牙轻度错患者作为研究对象,采用数字随机法,分为研究组和对照组各38例。对照组通过镍铬合金烤瓷冠进行修复,研究组采用二氧化锆全瓷冠修复,对比两组临床疗效。结果:研究组修复体牙龈反应以及龈缘灰线合格率均高于对照组,P<0.05;其他合格率对比无明显差异,P>0.05。结论:二氧化锆全瓷冠修复成人前牙轻度错具有良好的临床疗效,应根据患者的实际情况,进行良好的修复前准备、基牙预备、过渡性修复体制作、材料选择等。
Objective: To investigate the clinical efficacy of zirconium dioxide all-ceramic crown restoration on the repair of adult anterior teeth mild malocclusion. Methods: A total of 76 patients with anterior teeth mild malocclusion in a hospital were selected as study subjects and divided into two groups according to the digital number method: study group and control group. The control group was repaired with nickel-chromium alloy porcelain crown. The study group was repaired with a zirconium dioxide all-ceramic crown and the clinical efficacy of the two groups was compared. Results: The gingival reaction of the prosthesis and the qualified rate of the gray line on the margin in the study group were higher than those in the control group(P<0.05). There was no significant difference in other qualified rates, P>0.05. Conclusion: Zirconium dioxide all-ceramic crown restoration have a good clinical effect on the repair of adult anterior teeth mild malocclusion. Good pre-restoration preparation, abutment preparation, transitional prosthesis preparation and material selection should be performed according to the actual situation of patients.
