Abstract

Maxillary bone defects may follow surgical treatment of benign and malignant tumors, trauma, and infection. Palatal defects often lead to problems with swallowing and pronunciation from the leakage of air into the nasal cavity and sinus. Obturators have been commonly used to solve these problems, but long-term use of the device may cause irritation of the oral mucosa or damage to the abutment teeth. Utilizing implants in the edentulous area for the fabrication of the obturators has gained attention. This case report describes a patient, who had undergone partial resection of the maxilla due to adenocarcinoma, in need of a new obturator after losing abutment teeth after long-term use of the previous obturator. Implants were placed in strategic locations, and an implant-retained maxillary obturator was fabricated, showing satisfactory results in the rehabilitation of multiple aspects, including palatal defect, masticatory function, swallowing, pronunciation, and aesthetics.

상악골 결손은 양성 및 악성 종양, 외상, 감염 등의 수술적 치료에 의해 발생할 수 있다. 구개부의 결함이 발생하며 부비동과 비강으로 음식이나 액체가 통과하는 연하 문제나 비강으로의 공기 누출로 인해 발음 문제가 발생한다. 이를 해소하기 위해 폐색장치가 일반적으로 사용되나, 장기간 사용 시 구강 점막의 자극, 지대치 손상 등의 문제점이 발생할 수 있다. 최근에는 지대치 상실부위에 임플란트를 활용한 폐색장치 제작법이 각광받고 있다. 본 증례보고에서는 상악의 선암종으로 인한 부분 절제술을 받은 환자가 폐색장치의 장기간 사용 후 지대치가 상실되어 해당 부위를 임플란트로 수복, 임플란트 유지 상악 폐색장치를 제작, 적용하여 결손의 재활 및 저작, 연하, 발음, 심미성 개선 측면에서 양호한 결과를 보여 보고하는 바이다.
