Full-mouth rehabilitation of a patient with severe deep bite: a clinical report

Increasing the vertical dimension is essential to resolving problems associated with deep bite. Restorative dentistry, orthodontia, and oral surgery are the three disciplines that can help to gain the vertical dimension necessary in these patients. This clinical report presents the results of increasing vertical dimension with a full-mouth restorative treatment procedure for a 40-year-old male patient who exhibited severe deep bite. After clinical evaluation, extraoral examination showed a reduction of the lower facial height and protuberant lips, wrinkles, drooping, and overclosed commissures. In addition, intraoral examination showed a severe anterior deep-bite articulation, and upper incisors were in contact with the lower incisor labial tissue. A removable partial denture was made at increased occlusal vertical dimension (OVD) to use in the first stage of rehabilitation. Diagnostic wax-up was performed at the increased vertical dimension. Then, provisional crowns were fabricated according to this increased vertical dimension. Interim prostheses were used for 3 months as a guide for preparing the definitive restorations. The adaptation of the patient to the increased OVD was evaluated. During this period, he was asymptomatic. Following the evaluation period, definitive restorations were completed, and routine clinical assessments were made after 1 week, 1 month, 3 months, and 6 months, then after 1 and 2 years with visual and radiographic examinations.
