Full-Mouth Rehabilitation of a Patient with Severely Worn Dentition and Uneven Occlusal Plane: A Clinical Report

Severe tooth wear is frequently multifactorial and variable. Successful management is a subject of interest in dentistry. A critical aspect is to determine the occlusal vertical dimension (OVD) and a systematic approach that can lead to a predictable and favorable treatment prognosis. Management of patients with worn dentition is complex and difficult. Accurate clinical and radiographic examinations, a diagnostic wax-up, and determining OVD are crucial. Using mini-implants as orthodontic anchorage may facilitate orthodontic movement of teeth to improve their position, which is necessary for favorable prosthetic treatment. A 46-year-old man was referred for restoration of his worn and missing teeth. After diagnostic work-up, provisional removable prostheses were fabricated for both jaws, evaluated clinically, and adjusted according to esthetic, phonetic, and vertical dimension criteria. Clinical crown lengthening and free gingival graft procedures were performed in appropriate areas. Drifting of the left posterior mandibular teeth was corrected using mini-implants as orthodontic anchorage. Two conventional implants were inserted in the right mandibular edentulous area. After endodontic therapy of worn teeth, custom-cast gold dowels and cores were fabricated, and provisional removable prostheses were replaced with fixed provisional restorations. Metal-ceramic restorations were fabricated, and a removable partial denture with attachments was fabricated for maxillary edentulous areas. An occlusal splint was used to protect the restorations. Full-mouth rehabilitation of the patient with severely worn dentition and an uneven occlusal plane was found to be successful after 3 years of follow-up. This result can encourage clinicians to seek accurate diagnosis and treatment planning to treat such patients.
