Abstract
Maxillary defects caused by surgical resection of the jaw can sometimes significantly impair vital functions such as articulation and food intake. When functional restoration, such as that achieved with a dento-maxillary prosthesis （prosthetic reconstruction）, is selected for maxillary resection, an intraoral apparatus is required to improve the residual disorder. In our department, the intraoral apparatus is prepared before surgery, and intervention is started early for cases in which prosthetic reconstruction was determined at the preoperative clinical conference with departments related to head and neck surgery. The present case suffered from an edentulous unilateral maxillary defect, an obturator was fabricated twice using the method of directly relining the base plate, which was made using a polyethylene terephthalate （PET） sheet （by means of the base plate relining method）, and early restoration of oral function was achieved. Since the base plate relining method facilitates repeat fabrication, it seems useful for managing maxillary wounds. The prosthetic reconstruction method was established with multidisciplinary medical staff. The perioperative prosthetic management method is reported from the perspective of a dental clinician engaged in oral functional restoration.
