Objectives: to compare the accuracy of bracket placement using L shaped printed guide and digital indirect tray using virtual models.
Methods: This randomized clinical trial included 20 patients selected from the orthodontic outpatient clinics at Al-Azhar University, Assiut. Patients with full permanent dentition with complete clinical crown height and no previous orthodontic treatment were randomly assigned to receive bracket bonding by L shaped guide and digital indirect tray to obtain virtual models prebonding and post bonding to detect the deviation (linear and angular) of brackets for two methods. The variables were measured for each patient in each group for incisors, canines, and premolars.
Results: The guided group showed less deviation than indirect group with significant difference between them present at all linear variables for all teeth except for premolar at mesiodistal deviation while angular deviation showed only differences in some brackets for certain teeth.
Conclusion: Guided method provided more precise technique for bracket bonding at accurate position at different planes when compared to indirect tray method.
