Abstract
Introduction: Indirect bonding is a procedure that involves transferring orthodontic attachments from dental casts (working models) and bonding them to the teeth with the help of a transfer tray. Indirect bonding is a preferred approach for many orthodontists since it takes less time than direct bonding. The merging of computer-aided design and computer-aided manufacturing (CAD/CAM) allowed for the digital formation of transfer trays. This study aimed to determine the accuracy of CAD/CAM indirect three-dimensional printed bonding trays. Materials and methods: 140 teeth were planned to be bonded by 3D printed transfer tray. The intraoral scanner was first used to produce a stereolithographic (STL) file for virtual brackets location, and then another scan was taken after the brackets were bonded. Software was used to measure position deviation of bracket placements by superimposing virtual STL files and post bonding STL files. Results: To see if the mean transfer error was statistically within the selected accuracy limits of 0.5 mm for linear measurements, a one-sample t-test was used. For linear measurements, P-values of less than 0.05 indicated differences within the accepted deviation limits. Conclusions: CAD/CAM transfer trays for indirect bonding have high transfer accuracy in all kinds of teeth.
