摘要:
目的　通过对比分析基于数字化印模与传统印模制作的修复体的边缘适应性、邻接关系和咬合关系，探讨2种方法在临床应用中的优劣。方法　选择2015年8月至2016年6月在南阳市口腔医院行全瓷修复术患者78例共126颗患牙，分为A、B组。A组患牙60颗（冠修复A1组38颗；贴面修复A2组22颗，贴面限上前牙）采用数字化印模法；B组患牙66颗（冠修复B1组42颗，贴面修复B2组24颗）采用传统硅橡胶印模法，统计分析并比较2种方法制作的修复体的边缘适合性、邻接关系、咬合关系等。结果　2种印模方法所制作冠修复或贴面修复后，其边缘适合性、邻接关系A1 组优于B1组（χ2=3.85、13.66，P<0.05），A2组优于B2组（χ2=7.64、5.09，P<0.05），其咬合关系A1组与B1组、A2组与B2组比较差异均无统计学意义（χ2=0.13、0.08，P>0.05）。结论　数字化印模制作的修复体边缘适合性和邻接关系优于传统印模。
Abstract:
Objective　To explore the advantages and disadvantages of the two methods in clinical application by comparing the edge adaptability，adjacency relationship and occlusal relationship of the restoration of digital impression or traditional impression.Methods　A total of 126 teeth of 78 patients with all-ceramic restoration from August 2015 to June 2016 in Stomatological Hospital of Nanyang City were randomly divided into group A and group B.Sixty teeth in group A including 38 teeth with crown repair（group A1） and 22 teeth with veneer repair（group A2） were treated with digital impression method；while 66 teeth in group B including 42 teeth with crown repair（group B），24 teeth with veneer repair（group B2） were treated with the traditional silicone rubber impression method.The differences of edge adaptability，adjacency relationship and occlusal relationship of the restoration made by the two methods were compared.Results　The edge adaptability and adjacency relationship of crown or veneer restoration in group A1 and A2 were better than those in group B1 and B2（χ2=3.85，13.66，P<0.05；χ2=7.64，5.09，P<0.05）.There was no significant difference in the occlusal relationship between group A1 and B1（χ2=0.13，P>0.05），the same results were found between group A2 and B2（χ2=0.08，P>0.05）.Conclusion　The edge suitability and adjacency of the restoration made by digital impression are better than that of the traditional impression.
