| Abstract | ||||
| Aim: to measure the accuracy of brackets transfer with two indirect bonding techniques using three dimensional scanning. Subjects and Methods: Two hundred brackets were bonded to twenty subjects (upper arch) receiving orthodontic treatments. Orthodontic brackets were placed on the casts with a specific water soluble adhesive. After bracket placement, three dimensional scans of the casts obtained. Two types of transfer trays were fabricated, and used to bracket transfer to patient’s teeth. After bracket transfer another three dimensional scans of the subjects obtained. The teeth on one model will be then digitally superimposed to the corresponding teeth on the other model. All data collected will be tabulated and statistically analyzed. Results: The indirect bonding methods for both groups that were used in this study were precise and dependable within acceptable limits with directional bias especially toward gingival direction. Conclusion: Single sheet vacuum formed techniques were significantly less accurate than duple sheet vacuum formed technique in the Occluso-gingival direction | ||||
