Official title
A Comparison of Class II Correction Using the Carriere Motion Appliance Versus an In-Office Sectional Appliance: Treatment Effects and Efficiency
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The "sagittal first" approach to Class II correction in orthodontic treatment involves correcting the antero-posterior (AP) relationship of the maxillary and mandibular dentition prior to the leveling and aligning phase of orthodontic treatment. The Carriere Motion Appliance (CMA) was made to provide sagittal correction prior to orthodontic treatment with minimal secondary tooth movements that are typically seen with Class II correction. The aim in this study is to explore the efficacy and efficiency of Class II molar correction in adolescent patients using the sagittal first approach with either a sectional, in-office fabricated appliance or the CMA, by measuring total treatment duration (in months) as well as comparing dental and skeletal measurements taken from lateral cephalometric radiographs obtained prior to Class II correction (T0) and immediately after removal of the appliance (T1). The investigators will also be comparing secondary molar and canine rotational movements after Class II correction by comparing digital dental casts obtained at T0 and T1.
