Abstract

In the case of congenital malformation, acquired trauma, or maxillectomy by neoplasm, the defect in maxilla is combined with nasal cavity, maxillary sinus and oral cavity. This results in abnormal function in pronunciation, mastication, and swallowing. In this situation, the purposes of prosthodontics are also applied. The purposes of obturator for acquired maxillary deficiency patients are restoring pronunciation, mastication, and swallowing, and make patients comfortable and esthetic satisfaction. Reducing weight of the obturator makes edentulous ridge heathy and functional. It also improves patients' comfort. Hollow obturator also reduces unnecessary stress because improves physiologic function, as it weights less than 6.55-33.06% compare to usual one. This case presents the double-processing method for maxillary obturator in the patient treated hemi-maxillectomy due to malignancy neoplasm. We report this case because the patient acquired functional and esthetic satisfaction from double-processing obturator.

선천적 기형이나 후천적인 외상 또는 신생물에 의해 상악골 절제술을 받은 경우, 상악에서 발생하는 구강내 결손은 흔히 비강과 상악동 및 구강이 연결된 형태로 나타난다. 이러한 상악골의 결손은 구강과 비강이 교통되어 발음, 저작, 연하 등의 기능에 이상을 초래하게 된다. 이러한 경우에도 보철치료의 기본적인 목표가 적용되며, 후천적 상악 결손부에 수복되는 폐색장치는 발음, 연하, 저작 기능을 회복할 수 있어야 하고, 적절한 심미적 만족을 제공해야 하며, 환자가 편안하게 사용할 수 있어야 한다. 상악 폐색장치의 무게를 감소시키는 것은 잔존 조직의 건강과 정상적인 기능 및 환자의 안락함을 개선시킬 수 있다. 개방형 폐색장치는 결손부의 크기에 따라 6.55~33.06% 까지 무게를 줄여줌으로써 환자에게 편안함과 편의성을 제공해 주며, 생리적 기능을 향상시켜 치아와 지지 조직에 불필요하게 가해지는 부하를 감소시켜 준다. 본 증례는 hemi-maxillectomy를 시행한 환자에서 이중온성법을 이용하여 기존의 방법보다 더 균일한 의치상 두께를 가진 폐색장치를 제작하여 환자의 기능적, 심미적인 만족을 얻었기에 이를 보고하는 바이다.
