Abstract
The surgical resection of malignant tumors often leads to severe bone and soft-tissue deficits that can result in difficulty swallowing, impaired speech, and facial disfigurement. Prosthetic rehabilitation of these patients becomes an integral part of the patient's recovery and allows for improvement in quality of life. This clinical report describes a patient who underwent an anterior maxillectomy secondary to squamous cell carcinoma. After the insertion of a polymethyl methacrylate (PMMA) interim resection prosthesis, the patient developed a severe allergic stomatitis reaction in the oral cavity and oropharynx. By using the patch test approach, true PMMA allergy was diagnosed along with a suitable PMMA replacement for the prosthesis. A subsequent prosthesis was fabricated from urethane dimethacrylate in place of the standard PMMA.
