烤瓷贴面修复前牙间隙临床效果评价

目的 评价烤瓷贴面修复前牙间隙2年的临床效果.方法 对32例因先天缺失、畸形小牙、后天牙体缺损等原因所至牙间隙患者,采用78个烤瓷贴面进行修复.分别于贴面粘接后2周及6、12、24个月复查.结果 75个贴面完整存在,2个贴面切端有小缺损,1个贴面完全脱落;2颗牙在6个月复查时有明显牙龈炎,此后明显改善;1个贴面粘结后表面颜色与邻牙不协调;未发现继发龋及边缘适合度不满意的记录.结论 在2年的研究其间,用烤瓷贴面修复前牙间隙是可靠的,具有良好的美观效果.

Clinical Evaluation of Using Porcelain Laminate Veneer to Close the Anterior Tooth Space

Objective To evaluate the 2 years clinical effect of using porcelain laminate veneer to close the anterior tooth space. Methods Porcelain laminate veneer was applied to 78 teeth of 32 patients. The restorative reasons included congenital tooth missing, malformation tooth, tooth defect, and the anterior tooth space caused by other reasons. The 75 teeth were evaluated before and after luting in 2 weeks and 6 to 24 months. Results 75 porcelain laminate veneers were intact, little wane existed in 2 veneers at the incisal area. During the follow up examination, obvious inflammation was found in 2 teeth. 1 tooth with veneers showed inconsistent colour match with their adjacent teeth. No secondary caries and unsatisfactory scores were recorded for marginal adaptation. Conclusion The two years research shows that applying porcelain laminate veneer to repair anterior teeth space has an excellent clinical performance and it can be easily accepted by patients.
