Abstract

Objective: to measure the accuracy of brackets transfer with two indirect bonding techniques using cone beam computed tomography. Materials and Methods: One hundred fourty brackets were bonded to fourteen subjects (upper arch) receiving orthodontic treatments. Orthodontic brackets will placed on the casts with an adhesive. After bracket placement, Cone beam computed tomography (CBCT) scans of the casts obtained .After bracket transfer another Cone beam computed tomography (CBCT) scans of the subjects obtained. The corresponding teeth on both models will then digitally superimposed. All data collected will be tabulated and statistically analyzed. Results: The indirect bonding method investigated in this study was accurate and reliable within the specified acceptable boundaries with directional bias specially toward gingival Conclusion: Vacuum formed technique were significantly less accurate than silicone based technique in the Occlusogingival direction.
