Abstract
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.关键词
