Introduction: This study aimed to compare the buccolingual inclination of the anterior and posterior teeth in subjects treated with self-ligating or conventional fixed appliances with and without rapid maxillary expansion. Methods: Seventy-one subjects with Class I malocclusion were divided in 3 groups. Group 1 comprised 24 subjects (17 females; 7 males, mean age of 13.94 + 2.87), treated with Roth prescription, Group 2 comprised 24 subjects (14 females; 10 males, mean age of 13.85 + 1.83) treated with Rapid Maxillary Expansion followed by conventional appliances using Roth prescription and Group 3 comprised 23 patients (12 females; 11 males, mean age of 14.75 + 1.34) treated with Damon system. Intergroup changes comparison were performed using one-way ANOVA Results: Significant differences between groups were found for the buccolingual inclinations of: left maxillary lateral incisor, right mandibular lateral incisor and canine, left mandibular posterior teeth and right mandibular molar. Conclusion: The left maxillary lateral incisor showed palatal inclination in Damon Group and buccal inclination in RME and conventional groups. Right mandibular lateral incisor and canine showed greater buccal inclination in Damon group than in RME group. Damon group showed greater posterior mandibular buccal inclination in most teeth during treatment than conventional and RME groups.
