【摘要】Objective To explore the influence of the marginal position of porcelain fused metal crown on beauty and periodontal health for anterior teeth. Methods 96 patients were treated by porcelatin fused metal crowns and were randomly divided into three groups. According to the difference in the marginal position of the crown patients were with crown margins up the gingival level,at the gingival level and under the gingival level.The degee of satisfaction,gingival crevicular fluid volume (GCF) , aspartate(AST) and alkaline phosphatase(ALP) were investigated at 1-month,3-month and 6-month after premanent restoration. Results The satisfaction survey of under the gingival level group and at the gingival level group were higher than up the gingival level group's.There was significant statistically difference. Conclusion Based on the results of this study, the crown with gingival margin at gingival level is better than others.Crown margin at gingival level should been chosen at most times by dentists.%目的：探讨不同冠边缘设计对前牙区金瓷全冠修复患者的美观和牙周健康的影响。

方法：选择需进行金属熔附烤瓷全冠修复病例96例，随机分成3个治疗组，根据冠的颈缘位置不同分别采用龈上冠边缘修复、平龈冠边缘修复和龈下冠边缘修复，调查3组患者全冠戴入后患者美观满意度，检测全冠戴入后龈沟液量及AST、ALP活性的变
化。

结果：龈下冠边缘修复和平龈冠边缘修复组患者美观满意度明显较龈上冠边缘修复组高；龈上冠边缘修复和平龈冠边缘修复组患者对牙周损伤明显较龈下冠边缘修复组低，差异均具有统计学意义（P<0.05）。

结论：全冠平龈冠边缘修复设计既不影响患者对美观方面的需求，又对龈沟液的影响较小，优于龈上冠边缘修复和龈下冠边缘修复，不考虑其他影响因素时，临床应优先选择。
