Lecture Description

Orthodontic treatment is applied to a wide area of oral maxillofacial areas to correct dental malocclusion and skeletal discrepancy. Therefore, for precise orthodontic diagnosis, it is necessary to accurate evaluation of deformity of skeletal structures as well as malocclusion of the teeth. In order to evaluate orthodontic treatment, it is necessary to evaluate the teeth including the root, and in the case of orthognathic surgery patients, it is also necessary to evaluate the temporomandibular joint. Cone-beam computed tomography (CBCT) has been used to overcome limitations of two-dimensional radiographs including distortion, magnification, and overlap of anatomical structures.

This presentation reports the results of a study using CBCT to evaluate whether the three-dimensional morphology of the mandibular condyle, glenoid fossa, and mandible correlated with menton deviation in facial asymmetry. In addition, it is showed that the methods of evaluating dental movement after orthodontic treatment using composite tooth model composed of an intraoral-scanned crown and a CBCT-scanned root and evaluating condylar displacement after orthognathic surgery using CBCT-generated cephalograms.
