Brief summary

To analyze the distalization or distal tooth displacement and derotation angle produced by Carriere Motion Appliance® (CMA) by using a repeatable and reproducible measurement digital technique.

Detailed description

15 patients with Class II molar and canine relationship were submitted to orthodontic treatment with CMA. All patients were exposed preoperatively (STL1) and postoperatively (STL2) to a digital impression and afterwards were uploaded into a specific cephalometric software to allow the automatic mesh networks alignment of the STL digital files. Subsequently, the distal tooth displacement of upper canines and first upper molars and also the derotation angle of first upper molars were measured. The repeatability and reproducibility were analyzed by Gage R&R statistical analysis.

Interventions
