Abstract

This report describes a 72-year-old patient for whom a maxillofacial prosthesis was created to treat trismus and jaw deviation after mandibulectomy for osteoradionecrosis following radiotherapy for cancer. The patient’s chief complaints were an ill-fitting denture, discomfort, and difficulty with mastication. Clinical examination revealed a right-sided lateral mandibular defect, trismus, and right-sided deviation of mandibular occlusion. The diagnosis was discomfort associated with ill-fitting dentures. A resin-based denture was created using the piezography technique. Although the patient was satisfied wearing the new resin-based prosthesis, it was thin because of the limited denture space and developed a fracture. Thereafter, a metal-based denture was fabricated. Digital impressions were obtained with an intraoral scanner. A prosthesis with a metal framework as an internal support was recreated using CAD/CAM technology. This case report demonstrates the feasibility of a digital workflow for prosthesis refabrication in a patient with complex mandibular defects.
