二氧化锆修复体在口腔修复中的应用效果观察

Effect observation of zirconium dioxide restoration in prosthodontics

目的:探讨二氧化锆修复体在口腔修复中的应用价值.方法:选取2009-02/2012-04口腔修复患者100例,将其按双盲随机方法分为参照组50例和试验组50例.参照组采用镍铬合金全瓷冠行牙齿修复;试验组采用二氧化锆全瓷冠行牙齿修复,将两.组患者牙齿美学修复效果及修复时间、费用、修复体不良现象进行比较.结果:①两组患者口腔修复治疗效果比较:试验组患者牙齿修复优良率高于参照组,差异有统计学意义(P<0.05).②两组患者修复时间、修复花费比较:两组患者修复时间、修复花费接近,差异无统计学意义(P>0.05).③两组患者修复体不良现象比较:参照组患者有3例(3颗牙)出现修复体折断,有3例(3颗牙)出现修复体崩瓷.试验组患者仅有1例(1颗牙)出现修复体崩瓷现象,差异有统计学意义(P<0.05).结论:二氧化锆修复体在口腔修复中的应用价值良好,且不会增加修复花费和修复时间,有利于减少修复体不良现象,值得推广.

AIM：To investigate the effect observation of zirconi-um dioxide restoration in prosthodontics.METHODS：A total of 100 patients who came to prosthodontics from February 2009 to A-pril 2012 were selected and divided into observation group and control group by randomized and double-blind method,with 50 cases in each group.PFM （Ni-Cr Alloy）crowns with gingival porcelain were adopted in the control group,while zirconium diox-ide with gingival porcelain was adopted in the observation group. The esthetic effect,restoration time,cost and side effect of resto-ration of the two groups were compared.RESULTS：①Effect comparison：Observation group was better than the control group, and the difference was statistically significant （P 〈0.05 ）.②Restoration time and cost comparison：Restoration time and cost comparison of two groups are similar,and the difference was not statistically significant （P〉0.05）.③Side effect comparison：In control group,restorations broken was observed in 3 cases （3 teeth）,and porcelain cracking was observed in 3 cases （3 teeth）.In observation group,porcelain cracking was observed in 1 case （1 tooth）.The difference was statistically significant （P 〈0.05）.CONCLUSION：Zirconium dioxide restoration is useful in prosthodontics.It takes less time and costs less money to re-store the teeth,causes less side effect,and is worthy of promo-tion.
