[A case report: occlusal guidance of Angle Class II malocclusion with dysfunction of the masticatory system]

The purpose of this study was to evaluate the condylar changes induced by Bionator therapy. The pre and post treatment Cephalometric, tomographic, and dental cast record were evaluated. An 11-Year, 8 month-old boy with malocclusion class II div. 1 was referred to the Pedodontic clinic of the Nippon Dental University Hospital with a chief complaint of Brxism and Protrusion. The medical history was non-contributory. The period of the observation was 3 years 2 months. Normal permanent occlusion was obtained after treatment. The cephalometric findings showed a favorable relationship between the results of the skeletal and dental changes. Also the results showed an effect on the maxilla and mandible stimulation, class II skeletal correction. Favorable changes in the mandibular condylar position using the Bionator were observed in tomographic records before and after treatment.
