牙唇面根充法联合烤瓷牙修复效果评价

目的评价牙唇面根充法进行根管治疗联合烤瓷牙修复改善上前牙前突和增进美观的临床疗效。方法选取我科2010年1月—2014年1月门诊就诊的上前牙前突患者100例,通过牙唇面根充法完成根管治疗后进行烤瓷牙修复。比较治疗前、后患者头颅侧位X线片测量数据和牙龈炎发生率,评价治疗后烤瓷牙外观及功能。应用SPSS18.0软件包对数据进行统计学分析。结果治疗后U1-SN、U1-X、U1-Y均显著低于治疗前（P<0.01）,治疗后U1-L1显著高于治疗前（P<0.01）;治疗后牙龈炎发生率显著下降（χ²=16.2749,P<0.01）。治疗后烤瓷牙整体轮廓、上前牙前突纠正、与邻牙匹配度和减轻深覆及深覆盖优良率分别为96.00%、95.00%、98.00%和91.00%。结论牙唇面根充法进行根管治疗联合烤瓷牙修复可以有效改善上前牙前突,增加美观,值得临床应用。

Evaluation of labial surface root filling combined with porcelain dental restoration

PURPOSE: To analyze the effect of porcelain dental restoration combined with labial surface root filling for the anterior teeth. METHODS: One hundred cases with anterior teeth protrusion treated in our department from January 2010 to January 2014 underwent porcelain dental restoration combined with labial surface root filling. The measurements in cephalometric X-ray films before and after treatment were compared, and porcelain dental appearance and function were evaluated. The data was statistically analyzed with SPSS18.0 software package. RESULTS: After treatment, U1-SN, U1-X, U1-Y were significantly lower than before treatment（P<0.01）. U1-L1 was significantly higher after treatment（P<0.01）. The incidence of gingivitis after treatment decreased significantly（χ²=16.2749,P=0.0000<0.01）. The excellent rate of outline of porcelain teeth after treatment, correction of protruding anterior teeth, fitting with adjacent teeth and alleviation of deep overbite and deep cover was 96.00%, 95.00%, 98.00% and 91.00%, respectively. CONCLUSIONS: Porcelain dental restoration after root canal treatment can effectively improve anterior teeth protrusion and increase the aesthetic appearance, which is worthy of clinical application.
