Orthodontic Treatment Outcomes of Self Ligating System Compared to Clear Aligner System
Orthodontic Treatment Outcomes of Self Ligating System Compared to Clear Aligner System : A Randomized Clinical Trial
연구 개요
상태
상세 설명
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.

실험적: Self ligating bracket (Damon Ultima)
Patient will be treated with self ligating bracket (Damon Ultima) until dental levelling alignment , crowding resolved and case will be finished
|
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 treatment mechanics, including use of inter-arch elastics, bite raiser, and finishing procedures will be standardized. All patients will receive oral hygiene instructions at each visit. In case of bracket failure, brackets will be rebonded using the same system within 24 hours, otherwise the case would be considered as dropout. |
|
실험적: Clear aligner system
Patient will be treated with thermoformed Clear aligner until dental levelling alignment , crowding resolved and case will be finished
|
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 used for interproximal reduction , in case of debond attachment should be bonded within 24 hours. |
