瓷贴面临床应用评价及与金属烤瓷冠的对照分析

Evaluation of porcelain laminate veneer in clinical application and contrast analysis to porcelain-fused-to-metal

目的对瓷贴面的临床应用进行评价,以及观察瓷贴面与金属烤瓷冠在牙龈边缘变色方面的影响。方法选择26例51颗瓷贴面修复的前牙,评价瓷贴面的美观效果、牙龈炎性反应、舒适度、边缘适合度,并与30例共52颗金属烤瓷冠修复的前牙在牙龈边缘变色方面进行比较。结果 51颗瓷贴面在美观效果、牙龈炎性反应、舒适度、边缘适合度方面分别达到88.2%、3.9%、94.1%、98.0%。金属烤瓷冠牙龈变色发生率(30.7%)明显高于瓷贴面组(3.9%)(P<0.05)。结论瓷贴面在牙龈边缘、美观等方面均优于烤瓷冠,是前牙比较理想的一种修复体。

Objective To evaluate in clinical application of porcelain laminate veneer and observe the effects of porcelain-fused-to-metal and porcelain laminate veneer on gingival edge of the discoloration.Methods 26 cases of 51 anterior teeth that had been repaired by procelain laminate veneer were selected.Evaluated the aesthetic effect,gingivitis,comfort and fitness edge of the porcelain laminate veneer.Compared the porcelain laminate veneer with 52 porcelain-fused-to-metal repair of anterior teeth of 30 cases at the edge of the discoloration.Results 51 porcelain laminate veneer in aesthetic effect,gingivitis reaction,comfort and fitness edge were 88.2%,3.9%,94.1% and 98.0% respectively.The incidence of gingival edge of the discoloraction was higher in porcelain-fused-to-metal group（30.7%） than in porcelain laminate veneer group（3.9%）（P 0.05）.Conclusion Effects of porcelain laminate veneer on the margin of gingival,aesthetic aspect etc,are superior to that of porcelain-fused-to mental.it is an ideal material in vepair of anterior teeth.
