  • 1Department of Prosthodontics and Research Institute of Oral Science, College of Dentistry, Gangneung-Wonju National University, Gangneung, Korea


Open bite is accompanied by decrease in tooth contact and overbite, and causes collapse of occlusal plane, mastication difficulties, speech disorders, changes in appearance, and lower occlusal force than normal. Open bite caused by temporomandibular joint disorder in adults with complete occlusion must be corrected after removal or stabilization of the causative factors. Orthodontic treatment, occlusal adjustment, prosthetic treatment, and surgical treatment can be the option of occlusal correction. This report describes about estimating the cause of occlusion change in two patients who developed an open bite due to mandibular displacement in adults with complete occlusion and different treatment approaches accordingly. In one patient, satisfactory result was obtained in functional and esthetic aspects through occlusal adjustment after stabilization of the temporomandibular joint.
