全锆冠与氧化锆全瓷冠在后牙固定修复中的临床效果比较

摘要

目的：对牙缺失患者分别进行全锆冠与氧化锆全瓷冠后牙固定修复，比较分析全锆冠与氧化锆全瓷冠用于修复的临床治疗效果．方法：选择本院2013-01／2014-02收治的56例因后牙缺失而需要修复的患者，根据牙齿缺损程度分为对照组和实验组，分别采用不同材料进行固定修复．其中实验组29例90颗后牙进行氧化锆全瓷冠桥修复，对照组27例87颗后牙进行氧化锆全锆冠桥修复，并统一追踪观察1～3年，通过对义齿的边缘适合性、牙冠外形，牙龈健康情况，是否崩瓷、色泽、破裂等情况进行对比评价．结果：对所有检查的指标进行比较发现，两组病例修复效果均无显著性差异（P＞0．05），无统计学意义．结论：在边缘美观性、密合性及抗折强度方面，采用氧化锆全锆冠与氧化锆全瓷冠桥修复均能够满足临床的要求．%AIM:To compare the repairing effects between the zirconia all-ceramic crown bridge and zirconia bridge in aesthetics restoration of molars.METHODS:82 cases were divided into two groups according to their damage of teeth,test group and con-trol group.The test group and control group were restorated with the all-ceramic crown bridge (29 patients,90 molars)and zirco-nia bridge (27 patients,87 molars),followed up for 1 ~3 years, checked and appraised the form,marginal adaptation,color of the crowns,the gingiva and crown fracture.RESULTS:After in-spection,there was no statistically difference in the effects be-tween the two kinds of restorations (P <0.05 ).CONCLU-SION:The two kinds of restoration can both meet clinical needs in the aesthetics,marginal adaptation and the flexural strength.
