Prosthetic rehabilitation of an extensive midfacial and palatal postsurgical defect with an implant-supported cross arch framework: a clinical report

Abstract

When aggressive cancer is surgically treated, the extent of the lesion dictates the amount of tissue excised. The removal of extensive amounts of tissue, including crucial landmarks, complicates prosthesis design. This clinical report details the rehabilitation of a patient who had a total maxillectomy coupled with extensive surgical removal of the midface. With the aid of computer-generated implant placement, a large computer-aided design and computer-aided manufacturing milled titanium framework, a Hader bar, and magnetic keepers, a successful implant retained definitive obturator and facial prosthesis were fabricated that satisfied both esthetic and functional needs.
