Analysis of the Effect oh the Carriere Motion 3D

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."

Procedure

This treatment was unilateral, with dental composite bites ramps behind canines

Primary outcomes

  1. Molar Angle class II correction

    Time frame: Up to 6 months

    Measured between the centro vestibular groove of the maxillar fisrt molar and the mesio vestibulair cusp tip of the mandibular molar in millimeters

Secondary outcomes

  1. Canine Angle class II correction

    Time frame: Up to 6 months

    Measurement performed between the maxillary canine cusp tip and the inter-dental space between the mandibular canine and premolar in millimeters

  2. Extrusion or intrusion

    Time frame: Up to 6 months

    Extrusion or intrusion of the maxillary canines and molars supporting the orthodontic appliance in millimeters

  3. Correction of the Class II canine relationship

    Time frame: Up to 6 months

    Mesured correction of the Class II canine relationship in millimeters

  4. Rotations

    Time frame: Up to 6 months

    Mesured of the Rotations of the molars and canines supporting the CMA in degrees

  5. Inter-incisal variations

    Time frame: Up to 6 months

    Mesure of the variation in the inter-incisal midline discrepancy in millimeters

  6. Arch depth

    Time frame: Up to 6 months

    Mesure of the variation in arch depth in millimeters
