摘　　要：目的探讨二氧化锆全瓷冠修复前牙的临床疗效。方法选择2010年5月—2012年7月在蚌埠医学院第二附属医院口腔科就诊的前牙需要全冠修复的患者78例共132颗患牙作为研究对象，随机分为观察组31例58颗患牙采用二氧化锆全瓷冠修复和对照组47例74颗患牙采用镍铬合金烤瓷冠修复，所有患者在修复完成后每隔6个月复查一次，观察记录并比较2组修复体外形、颜色匹配、边缘密合度、龈缘着色及牙龈健康状况。结果132颗患牙修复1～2年后，观察组58颗修复体在外形、颜色匹配、边缘密合度、龈缘着色方面满意合格率为100％，8颗患牙牙龈出现轻度炎症，龈不良反应率为13．8％。对照组74颗修复体，外形上，70颗合格，4颗不合格（2颗崩瓷，2颗有可见裂纹），满意合格率94．6％；颜色匹配上，57颗与邻牙颜色基本一致，满意合格率77．0％；边缘密合度方面，63颗较满意，合格率为85．1％；牙龈着色上，有58颗牙龈无着色，满意合格率78．4％；牙龈反应方面，26颗牙龈有不同程度的炎症，龈不良反应率为35．1％。2组修复体相比，在外形上差异无统计学意义（P〉0．05），在颜色匹配、边缘密合度、龈着色及牙龈健康方面差异较为显著（P均〈0．05）。结论二氧化锆全瓷冠比较镍铬合金烤瓷冠修复前牙美学效果更佳，且耐用性好，对牙周组织影响小，是前牙修复的理想材料。Abstract： Objective To investigate the clinical therapeutic effect of restoration anterior teeth with zirconium dioxide all- ceramic crowns. Methods One hundred and thirty two teeth of seventy eight patients who need all crowns restoration of anterior teeth from May 2010 to July 2012 were selected. The patients were divided in random into observation group（ 31 cases 58 teeth, which were restored with zirconium dioxide all-ceramic crowns） and control group （47 cases 74 teeth, which were restored with Nickel-chromium alloy Ceramic crowns）. All of the patients were followed up for every 6 months after the restoration ,the shape of prosthesis, color matching, edge adaptation, gingival border dye and health situation of gingival border were observed, recorded and compared. Results 1-2 years after restoration,in the observation group , the percent of pass of the 58 teeth was 100%. The shape, color matching, edge adaptation, gingival border dye of the 58 resto- ration teeth were good. Only 8 teeth gum appeared mild inflammation. And the gingival adverse reaction rate was 13.8% in the observation group. While in the control group,70 teeth were up to standard and 4 teeth were below standard. The percent of pass of the shape was 94.6%. Color matching of 57 teeth was nearly the same as the adjacent tooth color and he percent of pass was 77.0%. The percent of pass of the marginal adaptation was 85.1% and the percent of pass of the gingival coloring was 78.4%. About the gum responses ,26 teeth had phlogosis and the gingival adverse reaction rate was 35.1%. Compared two groups of restoration, the two groups showed no significant difference of prosthesis shape （P 〉 0.05 ）. But the color matching,edge adaptation,gingival border dye and health situation of gingival border showed signifi- cant difference between the two groups（ P 〈 0.05）. Conclusion The application of zirconium dioxide all-ceramic crowns was better than that of Nickel-chromium alloy Ceramic crowns at aesthetic effect in restoration of anterio
