Description

This case report describes the successful long-term prosthodontic treatment of a maxillectomy adolescent patient up to 7 years. The patient was a 12-year-old female who underwent right maxillary resection due to adenomatoid odontogenic tumor at Tokyo Medical and Dental University hospital. The patient was 15 years old at her first visit to our Maxillofacial Prosthetics clinic. There was no facial deformity, and the right maxillary molars and second premolar were lost by the tumor resection. The defect was reconstructed with buccal fatty tissue and there was no communication between the oral cavity and nasal cavity, however, the defect site was easily deformed by pressure. Because of tight teeth contact, we carefully analyzed the clearance of clasps and practiced teeth preparation on a study model before preparing the abutment teeth. In consideration of the patient’s esthetics and comfort, a metal based dento-maxillary prosthesis was fabricated. Occlusal contact and oral hygiene were checked, adjusted and maintained at regular intervals. Findings such as caries or broken clasps were absent throughout the 7-year follow-up.
