Abstract

Prosthetic rehabilitation of an edentulous patient who has a maxillary defect is difficult to achieve for many clinicians. The maxillary defect causes leakage of air during pronunciation and compromises denture stability, support and retention by reducing denture-bearing area and breaking peripheral seal. In these patients, the sizes and shapes of defects are very important factors which attribute to prognosis of maxillary obturators. This case report shows the prosthetic rehabilitation of the patient who had maxillectomy on the right maxillary sinus because of squamous cell carcinoma. The patient had a stepwise treatment protocol which started with pre-operative dental examination and followed by surgical, interim and definitive obturation phase. In this case, an acceptable level of retention could be obtained due to well-defined static defects and the preserved premaxillae and the patient was satisfied with the result of the treatment in the aspect of function and esthetics.

상악골 결손을 갖고 있는 무치악 환자를 폐쇄장치로 수복할 때 임상가들은 많은 어려움을 겪게 된다. 결손부를 통한 공기의 누출, 안정성과 지지의 부족, 감소된 의치 피개 면적은 의치의 흡착과 변연 폐쇄를 어렵게 한다. 본 증례는 편평상피암에 이환된 우측 상악동 부위에 상악골 절제술을 받은 무치악 환자로 술전 치과 검진, 수술용 폐쇄장치, 이행 폐쇄장치, 그리고 최종 폐쇄장치에 이르는 단계적 치료 과정을 통해 보철적 재건을 완료하였다. 본 증례의 환자는 전상악골 및 양측 상악 결절이 온전하며 한정된 크기의 결손부를 가져 적절한 유지와 지지를 갖는 폐쇄장치를 제작할 수 있었으며 심미 및 기능면에서 양호한 예후를 보였기에 이를 보고하는 바이다.
