采用金属嵌体与瓷嵌体及树脂嵌体修复后牙Ⅱ类洞牙体缺损的疗效和预后影响分析

Curative Effect and Prognosis ofⅡClass Hole Tooth Defect Impact Analysis of Metal Inlay Porcelain Inlay and Resin Inlay Restoration

目的研讨后牙Ⅱ类洞牙体缺损患者采用金属嵌体、瓷嵌体以及树脂嵌体修复的临床疗效和预后情况。方法选取2017年5月—2019年5月间在天津市和平区新兴街社区卫生服务中心接诊治疗的90例(90颗)后牙Ⅱ类洞牙体缺损患者作为观察对象,通过随机数表模式分为3组,每组各30例,A组采用金属嵌体修复,B组采用瓷嵌体修复,C组采用树脂嵌体修复,同时设立对照组为患牙对侧或对颌的同名牙,分析比较各组修复1年后的牙龈指数(GI)、菌斑指数(PI)及修复疗效。结果A组患者GI、PI指标值明显高于其对照组,并且高于B组与C组,差异有统计学意义(P<0.05);B组与C组患者GI、PI指标值比较、与各自对照组比较,差异无统计学意义(P>0.05)。B组、C组的患牙修复效果较A组均占优,差异有统计学意义(P<0.05)。结论对后牙Ⅱ类洞牙体缺损患者使用瓷嵌体或树脂嵌体修复,修复效果较金属嵌体均更理想,并且二者对牙龈的刺激程度不及金属嵌体,预后更令人满意,值得推荐。

Objective To study the curative effect and prognosis ofⅡClass hole tooth defect impact analysis of metal inlay porcelain inlay and resin inlay restoration.Methods 90 cases(90 teeth)from May,2017 to May,2019 after the tooth Class hole tooth defect are selected as research object.Through the stochastic indicator model,there were divided into three groups,with 30 cases in each group.Metal inlay was used in group A,porcelain inlay restoration in group B,and resin inlay restoration in group C.At the same time,teeth and jaw teeth of the same name are set to analyze gingival index(GI),plaque index(PI)and repair effect 1 year after repair.Results The GI and PI indexes of group A were significantly higher than those of the control group,and were higher than those of group B and group C.There is statistically significant difference(P<0.05).There is no statistically significant difference in GI and PI index values between group B and group C,as well as between group C and their respective control groups(P>0.05).Compared with group A,there was statistically significant difference in group B and group C in tooth repair(P<0.05).Conclusion In patients with classⅡhole tooth defect of posterior teeth with porcelain inlay or resin inlay repair,repair effect is more ideal than metal inlay.Stimulation of the gums and the two are not as good as the metal inlay.It is worth recommendation.
