钴铬合金烤瓷牙和二氧化锆烤瓷牙修复效果对比

摘要

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 zirco-nium 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 porce-lain 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 porce-lain teeth. Zirconium dioxide porcelain teeth is the first choice for patients with good economic conditions.%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。
