Abstract:
Objective: This study aimed to compare the changes in incisors’ position in cases
treated with conventional and Damon System self-ligating appliances. Methods:
The sample comprised 51 patients with Class I malocclusion, mild to moderate
crowding, treated without extractions, divided into 2 groups: Group 1 consisted of
20 patients treated with the Damon system, with a mean initial age of 15.00 years,
treated for a mean period of 2.01 years; and Group 2 comprised 31 patients
treated with conventional appliances, with a mean initial age of 14.98 years,
treated for a mean period of 1.81 years. The initial and final cephalograms of each
patient were measured. The intergroup comparisons were performed with
independent t or Mann-Whitney tests. Results: Both groups showed a mild
protrusion and a buccal inclination of the maxillary and mandibular incisors, with no
statistically significant difference between them. Conclusion: The changes in
incisors’ position were similar between the groups treated with conventional and
self-ligating Damon appliances.
