Filter by: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.
The aim of this study is to determine efficacy of OrthoPulse photobiomodulation on the rate of tooth movement during alignment for Subjects receiving fixed appliance orthodontic treatment.
The aim of this prospective, multicentric, randomized, open-label study is to assess the efficacy of the removable Twicare® as mandibular propulsive appliance in children aged from 7 to 12 years old in the course of their orthodontic treatment, showing its noninferiority with the removable Herbst. One untreated group will be included to control the internal validity of the study as recommend in noninferiority trials. Patients will have a follow-up every two months during 6 to 12 months as planned in routine care.
The goal of this project is to reduce the radiation exposure in orthodontic patients by the use of a new imaging protocols based on non-ionizing orthodontic records (e.g. digital dental models, three-dimensional photograph) The first step in this process is to develop and validate an orthodontic analysis able to assess craniofacial proportions, dental, skeletal, and facial soft tissue. The investigators working hypothesis is that data from three-dimensional facial photographs and from digital dental casts can be registered accurately and consistently, and the diagnostic information about tooth position and facial soft-tissue derived from them are comparable to x-ray derived data
Twin-Block treatment and Dynamax treatment for Class II division 1 malocclusion do not have different effects with regards to treatment duration, the quality of dento-occlusal outcome, skeletal and soft tissue profile, patient discomfort and gingival health.
