The patient was a 56-year-old male. In July 2006, due to carcinoma of the left maxillary sinus（T4bN0M0）, the patient underwent extended maxillectomy including cheek and orbit, and received radiation therapy of 70 Gy. The range of the defect was H4S1D2T4 using the HS classification, and F123 by the FC classification. After the completion of radiation therapy, an impression was taken to produce a dento-maxillary prosthesis. Regarding the structure of the dento-maxillary prosthesis, the base of the denture was connected to the connection area with a magnet. Furthermore, a facial prosthesis was retained within the connection area of the dento-maxillary prosthesis using another magnet. Thus, the dento-maxillary denture and facial prosthesis consisted of 3 parts including the connection area, and each appliance was connected using magnets, so that the prosthesis could be easily applied and removed. Although indications of maxillofacial prosthetic appliances with magnets are limited, they could be appropriate options in selected cases.
