To compare the effects of Damon Ultima, Damon Q2, and conventional bracket systems on maxillary dentoalveolar structures and the amount of tooth movement. A total of 60 patients (24 males, 36 females) were treated with conventional, Damon Q2, and Damon Ultima brackets (20 patients per group). Intraoral scans were performed with iTero Element™ 2 before treatment, after using round archwires (12 weeks), and after using angular archwires (8 weeks). Arch length, intercanine and intermolar distances, tooth rotation, bucco-lingual inclination (BLI), and angulation changes were analyzed with a 3D accuracy program (Geomagic Control X 2022, 3D Systems, USA). Comparative analyses between the groups were conducted using a one-way ANOVA (p 0.05) in rotation movement. Inter-canine and inter-molar distance changes were significant in both Damon systems. BLI and angulation movements of premolars, as well as angulation movements of incisors, were effectively measured. No significant movements were observed in other tooth groups with different brackets.
