About
Carriere Motion appliance (CMA) was designed to change a Class II molar relationship into a Class I relationship by distalizing the whole posterior maxillary segment by means of class II elastics and mandibular anchorage. To eliminate the adverse effects of CMA with class II elastics, we can use the CMA to distalize the maxillary posterior segment with intra-arch anchorage using infrazygomatic miniscrews. The aim of this study is to evaluate skeletaly anchored CMA for distalization of the maxillary buccal segment vs. conventionally anchored CMA by comparing skeletal and dental measurements obtained from lateral cephalometric radiographs obtained prior to treatment (T0) and immediately after correction of class II and remval of the appliance (T1).
