Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the transfer accuracy of 3D-printed trays for indirect bonding of orthodontic brackets in vivo. Accurate placement of orthodontic brackets at the beginning of treatment improves treatment efficiency and shortens treatment time. Indirect bonding is a method of placing orthodontic brackets on a plaster or digital model of the dentition, followed by the transfer of these brackets to the patients' teeth using a transfer tray. Various indirect bonding methods have been developed with the aim of improved bracket positioning and reduced chair time. The success of these methods ultimately depends on how reliably the precise positioning of the brackets on the model can be transferred to the patient's teeth.
