目的研究光固化复合树脂在前牙修复中的应用效果。方法案例分析法。回顾性分析我院近年采用光固化复合树脂进行前牙修复120例(252牙),观察1～5年内患者前牙修复效果。结果术后第1年光固化复合树脂前牙修复总有效率高达93.7%,第2年达87.3%,从第3年开始,前牙修复总有效率开始大幅降低,至第5年,修复总有效率72.2%显著低于第1年的93.7%(P<0.01)。结论光固化复合树脂前牙修复的近期疗效显著,远期效果不甚理想,需要从材料质量和操作技术方面进一步研究和完善。
Objective To study the application effect of light curing composite resin in anterior teeth repair. Method case analysis method A retrospective analysis of our hospital in recent years using light-cured composite resin for anterior teeth repair 120 cases (252 teeth), observed 1 to 5 years in patients with anterior teeth repair effect. Results The total effective rate of anterior teeth restoration in the first year after operation was as high as 93.7% and 87.3% in the second year. The total effective rate of the anterior teeth restoration began to decrease significantly from the third year to the fifth year, The effective rate of 72.2% was significantly lower than that of the first year (93.7%, P <0.01). Conclusion The curative effect of the light-cured composite resin anterior teeth repair is significant, the long-term effect is not ideal, need to further study and improve from the material quality and operation techniques.
