目的：对比二氧化锆全瓷冠与镍铬合金烤瓷冠在前牙修复的效果，从而探讨二氧化锆全瓷冠修复前牙缺失的的临床治疗效果。方法参照美国公共健康协会修订的标准，回顾性分析56例患者共77颗前牙行镍铬合金烤瓷冠、76例患者共102颗前牙行二氧化锆全瓷冠修复后的治疗效果。治疗效果的分析包括牙体缺损修复后的边缘牙龈颜色、边缘适合性、继发龈、健康等方面，从而综合评价二氧化锆全瓷冠对前牙牙体缺损修复的临床效果。结果102颗二氧化锆全瓷冠修复后前牙的牙龈颜色、边缘适合性、继发龈、健康等方面表现均明显优于56例镍铬合金烤瓷冠。4例患者共5颗牙出现了不同程度的崩瓷现象，但不影响患者的使用。结论二氧化锆全瓷冠修复前牙确实的临床治疗效果明显好于镍铬合金修复体，虽会出现崩瓷等现象，但不影响患者的使用。

Objective Tosummarizetheexperienceandclinicalrestorationeffectsofzirconiumdioxideceramiccrownsinthetreatmentof frontteethmissingbycomparingtheeffectofzirconiumdioxideceramiccrownandnichromebakedporcelaincrown.Methods 56patientswith77 teeth treated with nichrome baked porcelain crown and 76 patients with 102 teeth treated with porcelain -veneered zirconium dioxide ceramic crowns were included into this study. According to the modified criteria of USPHS( United States Public Health Service),the restorations and the supportingteethwerescrutinized.Results Theclinicaloutcomeofthezirconiumdioxideceramiccrownswasbetterthanthatofnichromebaked porcelaincrown.Conclusion Theporcelain-veneeredzirconiumdioxideceramiccrownsshowedgoodclinicalresults.Althoughveneerfracture could occur intezirconium dioxide ceramic crown group,the rate of veneer is very low and did not influence the normal application.
