CBCT study on the symmetry analysis of chin of the adult patients with skeletal Class Ⅲ mandibular deviation
Objective To evaluate the chin morphology and compensation,by analyzing the morphological and structural characteristics and symmetry of chin in adult patients with skeletal Class Ⅲ mandibular deviation.Methods Sixty-six patients with skeletal Class Ⅲ were selected and divided into deviation group(n=33)and control group(n=33).Morphology and symmetry of chin were evaluated based on CBCT examination data.Results The left deviation of mandible is more obvious in adult patients with skeletal Class Ⅲ mandibular deviation.The mental foramen was located in the center of the mandible.The deviated side had smaller chin unit length and inclination than the nondeviated side(P＜0.05).Conclusion There were asymmetry and compensation in the chin of adult patients withtype Ⅲmandibular deviation.
