Buccal Bone Changes With Self Ligating Brackets Versus Conventional Brackets. A Comparative Study
Year: 2010
Type: article
Abstract: Introduction: Self ligating brackets (SLB) manufacturers claim that expansion of arches and alveolar bone building is facilitated by their bracket design.The objective of this study was to determine whether SLB brackets have a different effect on buccal bone changes compared with conventional brackets (NSLB) during orthodontic treatment.Methods: Cone beam computed tomography (CBCT) images were obtained before and after treatment of 45 patients (26 treated with conventional brackets (NSLB) and 19 with SLB).The CBCT images were compared between groups for buccal bone height and thickness at the maxillary first molars, maxillary second and first premolars using imaging software.The intermolar distance and buccolingual angulation were assessed for the maxillary first molars as potentially confounding factors.Differences for each variable measured before and after treatment were compared between the two groups.Results: Initial and final thickness and height of buccal bone were significantly different between the teeth (p <0.001).The buccal bone height (p <0.001) and thickness (p= 0.018) significantly decreased after treatment for both groups.The mean changes of buccal bone height and thickness measured were not significantly different between SLB and NSLB groups (p>0.05).The intermolar distance and molar angulation changes were not significantly different between the 2 groups (p >0.05).The change in bone height depended on the initial bone thickness where the greater the initial bone thickness, the less the decrease in bone height (p <0.01).The change in bone thickness was affected by the change CHAPTER 1
