Abstract
AIM : To measure and compare bracket transfer accuracy of five indirect bonding ( IDB) techniques. MATERIALS AND METHODS : Five groups were studied. In each group 10 working models and 10 study models are taken. Group I – PolyVinyl Si loxane (PVS – Putty), Group II – Single Vacuum Form (Single -VF), Group III – Clear Polyvinyl Si loxane (PVS-Clear), Group IV - Double Vacuum Form - Double VF, Group V – Polyvinyl Si loxane (Clear) Vacuum form (PVS-VF). Brackets were bonded on 50 identical stone working models (10 per technique) . IDB t rays were fabricated to transfer brackets to another 50 identical stone study models (10 per technique) . The MesioDistal (M-D: x-axis) , OcclusoGingival (O-G: y-axis) , and BuccoLingual (B-L: z-axis) positions of each bracket are measured using the Photographic and Caliper measurements. RESULTS : When the techniques were compared, bracket transfer accuracy was similar for PVS-VF, PVS-Clear, and PVS putty, whereas Double - VF showed significantly less accuracy in the O-G direct ion. Single VF was less accurate in al l three direct ions (M-D, O-G & B-L) . CONCLUSION : Based on the findings of the present study, overall differences in bracket position were relatively small . Silicone-based trays had consistently high accuracy in transferring brackets, whereas methods that exclusively used vacuum- formed t rays were less consistent.
