[摘要] 目的 对比钴铬合金烤瓷牙和二氧化锆烤瓷牙修复效果。 方法 回顾性分析2010年1月—2013年12月在该科进行烤瓷牙修复术的96例(172颗牙)的临床资料,采取二氧化锆烤瓷牙的患者有38例(70颗牙),作为二氧化锆组;采取钴铬合金烤瓷牙的患者有58例(102颗牙),作为钴铬合金组,对比两组患者的临床效果。 结果 二氧化锆的有效率34例(94.73%)与钴铬合金组的有效率53(91.37%)相比,差异无统计学意义(χ2=0.87,P>0.05)。但是两组患者治疗后,钴铬合金组并发症发生率高于二氧化锆组,差异有统计学意义(χ2=3.95,P<0.05)。 结论 二氧化锆烤瓷牙的疗效优于钴铬合金烤瓷牙,若患者经济条件允许,应该优先考虑二氧化锆烤瓷牙。

[Abstract] Objective To compare repairing effect of cobalt chromium alloy porcelain teeth and zirconium dioxide porcelain teeth. Methods To retrospective analyze 96 cases(172 tooth)clinical data of porcelain teeth prosthesis in our department from January 2010 to December 2013, the patients of zirconium dioxide porcelain teeth were 38 cases(70 tooth),which was zirconium dioxide porcelain teeth group,the patients of cobalt chromium alloy porcelain teeth were 58 cases(102 tooth), which was cobalt chromium alloy porcelain teeth group,the clinical result of two groups were compared. Results The effective rate 34 cases(94.73%)of zirconium dioxide porcelain teeth and effective rate 53 cases(91.37%)of cobalt chromium alloy porcelain teeth were compared, which was no difference(χ2=0.87,P>0.05). But after treatment of two groups,incidence of complications of cobalt chromium alloy porcelain teeth group were higher than those of zirconium dioxide porcelain teeth group(χ2=3.95,P<0.05), the difference were statistical significance. Conclusion The effective result of zirconium dioxide porcelain teeth are better than that of zirconium dioxide porcelain teeth. Zirconium dioxide porcelain teeth is the first choice for patients with good economic conditions.

烤瓷牙是目前临床牙体现代美容与修复的重要之一,其指的是用铸造贵金属作为支撑的内核,而后通过高温条件将专用的瓷性材料绕结在贵金属表面,并模仿正常牙体的一种牙齿修复方式[1-2]。由于烤瓷牙具有与牙体相近的外形、色泽,临床运用中获得了较满意的修复效果[3-4]。该课题研究中主要分析了钴铬合金烤瓷牙与二氧化锆烤瓷牙在临床应用中的分析效果,现报道如下。

1 资料与方法

1.1 一般资料

回顾性分析2010年1月—2013年12月在该院进行烤瓷牙修复术的96例(172颗牙)的临床资料。其中男44例,女52例。年龄区间在为22~65岁,平均年龄45.5岁。96例烤瓷牙修复术中,采取钴铬合金烤瓷牙的患者有58例(102颗牙),纳入钴铬合金组,采用钴铬合金烤瓷牙修复。采取二氧化锆烤瓷牙的患者有38例(70颗牙),纳入二氧化锆组,采用二氧化锆烤瓷牙修复。予以……
