| 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 in group 1 (traditional group) and digitally positioned by (3-Shap) software in group 2 (digital group). 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 accurate and reliable within acceptable limits with directional bias especially toward gingival direction. Conclusion: Traditional techniques with vacuum formed trays were significantly less accurate than digital technique with 3-D printed trays in the Occluso-gingival direction. | ||
