Effect Analysis of CAD/CAM Resin Temporary Crown in Repairing Large Defects of Deciduous Anterior Teeth
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.
