摘　　要：目的:分析计算机辅助设计与制造(Computer aided design/Computer aided manufacturing,CAD/CAM)树脂暂时冠修复乳前牙大面积缺损的疗效。方法:选取2018年2月-2023年6月于笔者医院进行治疗的108例乳前牙大面积缺损患儿为研究对象,依据入院先后顺序将其分为两组。对照组给予光固化复合树脂充填(n=54),观察组给予CAD/CAM树脂暂时冠修复(n=54),观察两组患儿的修复效果。结果:修复后3个月,两组缺损乳前牙修复体表面情况、色泽协调性、边缘密合度、继发龋比较差异均无统计学意义(P>0.05),修复后6个月,观察组缺损乳前牙修复体表面、色泽协调性、边缘密合度、继发龋有效率均高于对照组(P<0.05)。修复后3个月和6个月,两组缺损乳前牙牙龈炎症比较差异均无统计学意义(P>0.05)。结论:CAD/CAM树脂暂时冠在乳前牙大面积缺损修复中的效果较好,较光固化复合树脂充填更能够改善患儿远期预后。Objective To analyze the application effect of computer aided design and manufacturing(CAD/CAM)resin temporary crowns in children with severe defects of primary anterior teeth.Methods 108 children with severe defects of primary anterior teeth who were treated in author's hospital from February 2018 to June 2023 were selected as the study objects.According to the order of admission,they were divided into two groups.One group was filled with light cured composite resin(control group,n=54),and the other group was filled with CAD/CAM resin temporary crown(observation group,n=54).The repair effects of the two groups of children were observed.Results At 3 months after restoration,there was no significant difference between the two groups in the surface condition,color coordination,edge adhesion and secondary caries of the defective primary anterior teeth restoration(P>0.05).At 6 months after restoration,the surface condition,color coordination,edge adhesion and secondary caries effective rate of the observation group were higher than those of the control group(P<0.05).There was no significant difference in gingivitis between the two groups at 3 and 6 months after restoration(P>0.05).Conclusion The application of CAD/CAM resin temporary crowns in children with severe defects of primary anterior teeth is effective,and it can improve the long-term prognosis of children more than light cured composite resin filling.
