Buccal Alveolar Bone Thickness Assessment using CBCT before and after Orthodontic Treatment with Passive Self-Ligating Brackets: A Clinical Study

Dr. Ganesh Murugan

Abstract: Objective: The aim of the study was to assess and evaluate buccal alveolar bone thickness at different regions of maxilla by using Cone Beam Computed Tomography (CBCT) taken at pre-treatment and post orthodontic alignment intervals with the help of passive self-ligating brackets. Methods: This clinical study was carried out in Department of Orthodontics and Dentofacial Orthopaedics of a reputed Private Dental College. The study population was 15? 40-year-old subjects with sample size (n=16) whose CBCT scanned images were obtained. A simple random sampling technique was used. Results: In comparison between pre-treatment and post-treatment buccal alveolar bone thickness the mean value for orthodontic buccal alveolar bone thickness decreases post orthodontic alignment. Conclusion: Orthodontic alignment with Damon? Q self-ligating appliance generated dental arch expansion mainly due to tipping of teeth.
