目的：探讨金属烤瓷冠修复技术临床效果，总结金属烤瓷冠的最佳修复方法。方法选取2012年7月~2013年6月在本院口腔科就诊并选择金属烤瓷冠修复技术的120例患者的临床资料进行回顾性分析研究，根据修复体材料的不同分为观察组和对照组，各组60例，观察组采用金合内冠进行牙齿修复，对照组采用镍铬合金进行牙齿修复，修复后1年观察两组患者临床治疗效果及并发症发生情况，观察两种方法的优缺点，进行对比分析。结果观察组患者临床治疗总有效率为96.67%，显著高于对照组81.67%，差异有统计学意义(P<0.05)；观察组出现牙龈炎、牙龈肿痛出血、牙龈变色、口腔异味、全冠松脱等并发症的发生率显著低于对照组，差异有统计学意义(P<0.05)。结论金属烤瓷冠修复技术中金合内冠和镍铬合金均取得了满意疗效，金合内冠明显优于镍铬合金，金合内冠对牙周组织损伤小，不易出现牙龈炎、牙龈肿痛出血、牙龈变色、口腔异味及全冠松脱等并发症的发生，美观性好，是一种较为理想的修复方式，值得推广应用。

Objective To explore the clinical effect of metal-ceramic crown remediation technique and sum up the op-timal remediation of varieties of metal-ceramic crown. Methods Clinical data of 120 patients who visited our depart-ment and agreed on metal-ceramic crown remediation technique from July 2012 to June 2013 were retrospectively ana-lyzed and studied.Based on different remediation material,they were divided into observation group and control group,60 cases in each group.In observation group,inner crown in gold alloy was adopted for dental rehabilitation,while in control group,nichrome was chosen.One year after remediation,clinical therapeutic effect,occurrence of complications,advantage and disadvantage of two methods between two groups was analyzed and compared respectively. Results The total clini-cal therapeutic effect in observation group was 96.67%,much higher than that in control group accounting for 81.67%, with statistical difference (P<0.05).In observation group,incidence of complications like gingivitis,swelling and aching of gum,gingival bleeding,gingival discoloration,bad breath,and full crown loose was remarkably lower than that in control group,with statistical difference(P<0.05). Conclusion In the technique of metal-ceramic crown remediation,inner crown in gold alloy and nichrome both obtain satisfying effects,but the effect in the former is better than that in latter.Inner crown in gold alloy,at advantages of small damage to periodontium,few complications such as gingivitis,swelling and aching of gum,gingival bleeding,gingival discoloration,bad breath,and full crown loose and so forth,and high aesthetic perception,is a relatively ideal remediation,which is worthy of adoption and expansion.
