试论前牙金属烤瓷冠、氧化锆全瓷冠修复后牙周组织变化

摘要

Objective Changes of dental porcelain fused to metal crown, zirconia all ceramic crowns on the periodontal tissue of the former.Methods selected in our hospital in June 2014 to 2015 December for patients with anterior teeth with PFM crowns 100 cases as the research object,divided into observation and control group. Patients in the control group were treated by the cobalt chromium alloy porcelain crowns, the observation group with zirconia all ceramic crowns, comparative analysis of the clinical therapeutic effect of the two groups.Results observation group of gingival papilla color change, gingival grey line and black line occurred rate of gingivitis was signiifcantly lower than that of the control group. Conclusion zirconia all ceramic crown restoration has a strong aesthetic,can be used to repair the anterior teeth.%目的：研究前牙金属烤瓷冠、氧化锆全瓷冠修复后牙周组织的变化。方法选取我院2014年6月～2015年12月收治的进行前牙烤瓷冠修复患者100例为研究对象，将其分为观察与对照两组，对照组进行钴铬合金烤瓷冠修复，观察组采用氧化锆全瓷冠修复，对比分析两组临床治疗效果。结果观察组的龈乳头颜色改变、牙龈缘灰线、黑线发生率牙龈炎发生率显著低于对照组。结论氧化锆全瓷冠修复具有较强的美观性，临床上可以将其用来修复前牙。
