Evaluation of maxillary alveolar bone changes following canine retraction with different types of orthodontic brackets (cone beam study)
Keywords:
canine retraction, cone beam computerized tomography, bone thickness, mini screwAbstract
Background: The alveolar bone is traditionally and practically considered the anatomical limitation of orthodontic tooth movement. Canine retraction is important step in cases with incisor crowding where extraction provides space for incisor alignment without the need to procline them. Materials and methods: This randomized clinical trial was carried on twenty patients candidates for extraction camouflagic treatment. CBCT was done to all patients and buccal bone thickness was evaluated. The patients was devided into 2 groups. The treatment of group (A) was done using self-ligating brackets and group (B) treatment was done using conventional brackets. Canine retraction was done using sliding mechanics After canine retraction completion CBCT was done again and buccal bone thickness was evaluated again. Results: The results show that there was statistically significant increase in canine labial bone thickness at L1, L2 and L3 in group (A) and group (B) after canine retraction. The results show that there was statistically insignificant difference in percentage of change of canine labial bone thickness at L1, L2 and L3 between group (A) and (B). Conclusion: There was a statistically significant increase in labial bone thickness between (Pre) and (Post) groups with both conventional and SL brackets.
