Analysis of the Effect oh the Carriere Motion 3D

Analysis of the Effect oh the Carriere Motion 3D on Patients With Class II Subdivision : a Retrospective Study

Class II subdivision malocclusions are common and complex to treat due to their asymmetry. The range of orthodontic correction devices is expanding towards systems that are more comfortable for the patient but may not necessarily have scientific evidence to demonstrate their effectiveness. The aim of this study was therefore to evaluate, for the first time, the effect of a Class II correction device, namely the Carriere Motion 3D (CMA), on patients with a Class II subdivision malocclusion. Method:this retrospective observational study included all patients presenting with a Class II subdivision malocclusion and treated with CMA between July 2018 and November 2023. Before treatment (T0) and after treatment with CMA (T1), orthodontic data from dental molds and lateral cephalometric radiographs (Steiner analysis) were collected and statistically analyzed to assess dentoalveolar as well as skeletal effects of treatment using CMA."
