Brief Summary

The correlation between tooth inclination and bone thickness and the comparison between thickness measurements and buccolingual inclination before and after dental decompensation will be evaluated through tridimensional images in individuals with class III dentofacial deformities.

Conditions

Dentofacial Deformities

Keywords

Angle class III; tomography; tooth inclination; bone thickness

Outcome Measures

Primary Outcomes (1)

• Change in tooth inclination and bone thickness after tooth decompensation

  12 months after the begginning of orthodontic treatment, prior to orthognathic surgery

Study Arms (1)
