Title Comparative Evaluation of Treatment Outcomes between Damon Ultima and Pitts 21 Pro Bracket Systems; A Randomized Clinical Trial Abstract Background: The primary advantages of self-ligation brackets include faster archwire removal and ligation, reduced or eliminated need for chairside assistance, secure archwire engagement, and lower bracket-archwire friction, which collectively contribute to a substantial reduction in resistance to sliding and are theorized to enhance the efficiency of initial tooth alignment. This randomized controlled trial (RCT) will be conducted to assess differences in treatment outcomes with these two different self-ligation bracket systems.
Subjects/Materials and Methods: This randomized clinical trial included 40 participants with full permanent dentition (excluding third molars) exhibiting Angle Class I malocclusion with moderate crowding. Patients who were scheduled to undergo orthodontic treatment were allocated into two groups: Damon Ultima and Pitts 21 Pro. The total treatment duration will be measured in months from the bonding day to the completion of treatment, in addition to the number of visits.
Pre-treatment, post-alignment, and post-treatment records were obtained, including intraoral scans (IOS) for assessing alignment efficiency and arch parameters. Periapical radiographs of the upper and lower incisors were taken before and after treatment to measure the amount of root resorption. Treatment outcomes were evaluated using the American Board of Orthodontics (ABO) grading system. Additionally, pain perception and patient treatment perception were assessed.
Presence of full permanent dentition except the third molars.
Class I with moderate crowding requiring fixed appliance therapy and don't need extraction.
Good dental hygiene and periodontal health.
Good general health; no systemic conditions affecting bone metabolism or pain perception.
Severe skeletal discrepancies requiring orthognathic surgery, craniofacial anomalies). Patients with active periodontal disease or medically compromised patients.
