Official title
Orthodontic Treatment Outcomes of Self Ligating System Compared to Clear Aligner System : A Randomized Clinical Trial
Overview
This study is a multi-center, prospective, parallel-group randomized controlled trial designed to compare the orthodontic treatment outcomes of a passive self-ligating bracket system (Damon Ultima) versus a clear aligner system. The primary objective is to evaluate and compare the total orthodontic treatment duration between the two systems in patients with Angle Class I malocclusion and moderate crowding. Secondary objectives include assessing alignment efficiency, patient pain perception at multiple time intervals, dental arch dimension changes, root volume loss percentage, and overall treatment quality using the American Board of Orthodontics Objective Grading System (ABO-OGS).
Detailed description
Participants aged 17-32 years with full permanent dentition, Class I canine and molar relationships, and moderate crowding (4-8 mm) will be randomly assigned in a 1:1 ratio to either the Damon Ultima group or the Clear Aligner group.
For the Damon Ultima group, brackets will be bonded according to a standardized protocol, utilizing a precise archwire sequence from 0.014-inch CuNiTi up to 0.019x0.0275-inch stainless steel wires. For the Clear Aligner group, patients will be treated with a series of thermoformed removable aligners designed via digital software, with instructions to wear them for 22 hours per day, changing aligners every 2 weeks.
Outcome measurements will include total treatment duration in months, pain perception via a 10-cm Visual Analog Scale (VAS), dental arch changes on 3D digital models, and root resorption via Cone-Beam Computed Tomography (CBCT) radiographs.
Interventions
- Device self ligating bracket
Teeth will be bonded with Damon Ultima® bracket system by the same protocol of bonding for all patients with the same bonding materials, time and curing apparatus by highly filled light-cure adhesive (Enlight, Ormco Corp., Glendora, California, USA). Archwire sequence will be: 0.014-inch CuNiTi, 0.018-inch CuNiTi, 0.014×0.0275-inch CuNiTi, 0.018×0.0275-inch CuNiTi archwires and 0.019×0.0275-inch stainless steel Ultima finishing archwires if needed. Appointment intervals will be 6-8 weeks for tr - Device Clear aligner
a series of invisible thermoformed removable aligners after designed by software and delivered to patients after the digital scanning of the initial models. A series of nearly invisible appliances to incrementally move the teeth from their crowded initial position to their final straightened position, these subjects will instructed to wear each aligner 22 hours a day, 7 days a week . The anterior teeth will be reduce at each interproximal location by means of diamond-coated finishing strips use
Primary outcome measures
- Primary Objectives : Total Treatment Duration. [Time frame: From baseline (day of bonding/delivery) up to treatment completion (estimated 14 to 28 months).]
Secondary outcome measures (5)
- Patient Pain Perception. [Time frame: "Baseline (Day 1), and at 6 hours, 24 hours, 3 days, and 7 days following the initial appliance insertion and after each subsequent archwire activation or aligner change throughout the active treatment phase, up to 14 months."]
- Dental Arch Alignment Efficiency [Time frame: Baseline (Day 1) and at the completion of the leveling and alignment phase, up to 6 months.]
- Changes in Dental Arch Dimensions [Time frame: Baseline (Day 1) and through study completion, an average of 14 months]
- Root Volume Loss Percentage. [Time frame: Baseline (Day 1) and through study completion, an average of 14 months]
- Objective Grading System Score. [Time frame: Through study completion, an average of 14 months]
Eligibility criteria
Inclusion criteria
