目的探讨氧化铝渗透全瓷冠对前牙修复的治疗效果及常见并发症.方法选择2009年6月-2010年12月在我科就诊的患者,共计患牙276颗,其中上前牙162颗,下前牙104颗；将患者随机分为2组,治疗组140颗采用氧化铝全瓷冠修复,对照组136颗为为钻铬合金烤瓷熔附金属全冠修复.比较两组患者的治疗效果及并发症.结果经过12个月的治疗、随访,氧化铝全瓷冠组治疗效果明显高于钻铬合金烤瓷熔附金属组,差异具有显著性(P＜ 0.05);氧化铝全瓷冠组患者中牙龈炎及折裂崩瓷远低于钻铬合金烤瓷熔附金属组,差异具有显著性(P＜0.05).结论 Procera氧化铝全瓷冠修复前牙临床效果好、并发症较少,值得推广.

Objective To explore the clinical efficacy of alumina-based all ceramic crowns and the related complications.Methods 276 affected teeth including 162 maxillary anterior teeth and 104 lower anterior teeth in the patients who had treated during the period of June 2009 to December 2011 restoration were randomly divided into two groups.The patients in the study group were treated with inceram alumina all ceramic crowns,whereas the control group received Co-Cr alloy porcelain-fuse-to-metal crown.The efficacy and complication were compared between the two groups.Results After a 12-month follow-up,the efficacy was significantly higher in the study group than in the control group( P＜0.05 ).The incidence rates of gingivitis and break of the materials were markedly lower in the study group than in the control group ( P＜ 0.05 ).Conclusions Alumina-based all ceramic crowns is effective and has fewer complications in restoration of anterior teeth.It is worth popularizing.
