| Abstract Objective: This study was conducted to evaluate the accuracy of computer-aided full tray vs computer-aided sectional tray in indirect bonding of orthodontic brackets. Methods: Twenty patients (10 in each group) with mild to moderate crowding, requiring orthodontic treatment with full set of permanent teeth except for third molars, will be selected for this study. A total of 400 brackets will be used for both groups. The same bracket type and bonding material will used in both groups. The accuracy of bracket transfer will be measured by GOM software. Results: pre-transfer and post-transfer bracket positions showing that both transfer methods were accurate in reproducing the pretransfer bracket position onto the patient’s dentition in vivo at a clinically acceptable level, however sectional computer aided tray revealed better results as there was a statistically significant difference between the two groups in all dimensions (p<0.001) except occlusogingival dimension (p>0.05). Conclusion: Both Computer-aided indirect bonding transfer methods can be used with confidence as it is accurate and within the clinically accepted limits. Sectional computer aided indirect bonding method revealed better results in all dimensions as it had better control, better tray seating and more accurate transfer and can be used in cases with mild crowding .Although transfer errors were mainly in occlusogingival dimension towards gingival and in buccolingual towards buccal direction, still errors were within clinically acceptable limits.
