Abstract

When oral cancer develops in the maxilla, oro-nasal communication occurs after surgical treatment including removal of the primary site. Restoration through an obturator is necessary to prevent food from storing due to non-oral opening, and to ensure proper pronunciation and aesthetic restoration. In this case, the patient was treated with right hemi-maxillectomy due to oral cancer and has residual abutment and poor periodontal support due to the effect of head and neck radiotherapy. The obturator was treated with a hybrid telescopic double crown denture. Reporting a successful prognosis in 18 months of follow-up.

구강암이 상악에 발생하게 되면 원발 부위의 제거를 포함한 외과적 처치 후 비구강 개통(oro-nasal communication)이 발생하게 된다. 비구강 개통으로 인한 음식물의 저류를 막고 및 원할한 발음 및 심미적 회복을 위해서는 구강 폐색장치(Obturator)를 통한 수복이 필요하다.본 증례에서는 구강암으로 인해 우측 상악 편측절제술(hemi-maxillectomy) 시행하고 두경부 방사선 치료의 영향으로 인해 잔존 지대치의 우식과 불량한 치주지지를 보이는 환자에서 구강폐색장치(obturator)를 하이브리드형 이중관의치(hybrid telescopic double crown denture)로 수복하였다. 18개월 간 경과관찰에서 성공적인 예후를 보여 이를 보고하고자 한다.
