Overview
Brief Summary
Comparison of skeletal and dentoalveolar changes in skeletal class II correction with Advansync 2 between two different bracket prescriptions- A randomized controlled trial.
Aim: To compare the skeletal and dentoalveolar changes in skeletal class II correction achieved with Advansync 2 between two different bracket prescriptions.
Objective and rationale
To evaluate whether lower incisor proclination can be controlled when Advansync is used in conjunction with Damon. True and adequate mandibular advancement is achieved by maintaining average lower incisor inclination in the mandibular basal bone. Self ligating bracket system mainly achieves tooth alignment and relieves crowding by arch expansion. Arch expansion in Damon self ligating system is greater than that achieved in conventional pre-adjusted edgewise appliance. Excessive proclination of the lower incisors restrict forward rotation of the mandible and also hinders mandibular advancement. Thus this study was undertaken to evaluate the amount of mandibular advancement and other associated skeletal, dentoalveolar and soft tissue changes achieved by both the systems when used in conjunction with Advansync 2 appliance.
Sample size: 22 patients
Group 1: 11(Damon with Advansync) Group 2: 11 (MBT with Advansync)
Methodology:
22 growing subjects with Skeletal class II malocclusion selected based on their CVMI staging. Group A (11 subjects) to be treated with MBT with Advansync 2, and Group B (11 subjects) to be treated with Damon Q with Advansync 2. Sample size was determined using G power version 3.0.1 with power of 0.8. Simple random sampling to be done. Case records to be taken for each patient at pre- AdvanSync2 (T1) and post-AdvanSync2 (T2), which includes cephalometric radiographs, extraoral, and intraoral photographs. Informed consent to be obtained from each participant for the use of their case records for scientific research and publication
