Abstract
In a longitudinal observation case, it was found that morphological changes of the condylar head can be achieved by complete denture treatment.A 60-year-old edentulous female visited our clinic with complaints of spontaneous pain around the left TMJ and limitation of mouth opening (18 mm). MRI and TMJ radiograph showed osteophyte at the left condylar head, and internal derangement with anterior displacement without reduction of the left meniscus were observed.Through subsequent mandibular repositioning treatment of the patient, with the complete dentures applying centric relation as a treatment position, the condylar head shape and osteophyte were restored within 15 months. Clinical findings such as pain and mandibular disturbance disappeared after the initial three months following treatment, and kinesiologically, mandibular movement during open-close and chewing were improved.Therefore, it is suggested that abnormal changes of the condylar head are closely related to occlusion. Furthermore, it can be suggested that effective mandibular repositioning can be achieved by applying complete dentures as centric relation during treatment.
