INTRODUCTION: The introduction of the virtual occlusal set-up, limited to the permanent dentition with dento-dental and dento-alveolar discrepancies, based on the straight wire technique with final arches .020" x .025" ss in straight wire brackets .022" x .028" is an evolution of the 3D digital model with clinical impact. AIM: To present a computer-aided solution to orthodontic indirect bonding, allowing accurate positioning of straight-wire brackets based on a virtual occlusal set-up resulting from the treatment plan. MATERIAL AND METHODS: Computer-aided indirect bonding was applied in two cases: a Class II patient in the permanent dentition, crowding, rotation of upper and lower bicuspids and a Class I patient in the permanent dentition with already extracted 1.4, 2.4, 3.4, 4.4, severe crowding, rotation, arch form reduction. Speed brackets were utilized in both cases. RESULTS: In the first case the brackets' starting position on the patient corresponds to the final position on the virtual occlusal set-up. In the second case the resulting occlusion at the end of treatment corresponds to the final occlusion on the virtual occlusal set-up. DISCUSSION: The computerized tools employed in the process enabled precise bracket placement on the stone model. An algorithm from the virtual set-up is the determinant for the precision. CONCLUSION: Computer aided indirect bonding is a method of placing brackets precisely.
