Analysis of the failure causes of 3shape Trios 3 intraoral scanning and traditional silicone rubber in the repair of dental defects
Objective To analyze and compare the failure causes of 3shape Trios 3 intraoral scanning and traditional silicone rubber in the repair of dental defects,and to provide references for clinical mold extraction and performance improvement of intraoral scanner.Methods A retrospective analysis of 200 patients who underwent oral fixed repair and rework from January 2021 to October 2023 was conducted.The patients were divided into oral scan group(n=97)and silicone rubber group(n=103)by mold extraction.The oral scan group was given 3shape Trios 3 intraoral scan,and the silicone rubber group was given traditional silicone rubber.The failure causes of the two groups in the repair of dental defects were compared.Results There was a statistically significant difference in the distribution of dental defect repair failure between the two groups(P＜0.05);in the oral scan group,the proportion of subgingival defect repair failure was higher than that of supragingival defect(P＜0.05).There was a statistically significant difference in the causes of failure of subgingival defect repair between the two groups(P＜0.05).Conclusion Compared with traditional silicone rubber,3shape Trios 3 intraoral scanning has more advantages in the repair of supragingival defects,but in the repair of subgingival defects,the application effect of silicone rubber is better.
