Abstract

The maxillary defects lead to anatomical and functional deformity of the maxillofacial region. As far as functions are concerned, such defects can produce difficulty in speech, mastication, and deglutition. Obturator prostheses play a very important role in functional recovery for post-maxillectomy patients. To achieve rigidity of the obturator, appropriate retention should be given, and the weight of the prosthesis be reduced. There are two types of hollow bulb obturator: open and closed. A closed type has many advantages. Nevertheless, some problems, including complexity of fabrication and water leakage into the bulb, have the closed hollow obturator not be widely used. The one-step polymerization technique described in this case overcomes the shortcomings by easily constructing a small hollow bulb with two thermoplastic resin sheets.

상악골 결손은 악안면 부위의 해부학적 기형과 기능 장애를 초래한다. 기능적 측면에서, 상악골 결손은 발음, 저작, 연하 장애를 일으킬 수 있다. 상악절제술을 받은 환자에게 폐색장치는 이러한 기능적 회복에 큰 역할을 한다. 폐색장치가 구강 내에서 적절히 기능하기 위해서는 충분한 유지가 필요하며, 이러한 유지의 증가를 위해서는 폐색장치의 무게 감소가 필요하다. Hollow bulb 폐색장치에는 개방형, 폐쇄형 두 가지 형태가 존재한다. 폐쇄형 형태는 많은 장점을 가지나, 제작이 어렵고 누수가 발생할 경우 처치의 어려움 등의 단점이 존재하여 많은 술자들은 개방형 형태로 제작한다. 본 증례에서 두 열가소성 레진 시트로 만든 hollow body를 이용하여 one-step 중합 기술로 폐쇄형 hollow bulb 폐색장치를 제작하였고, 이는 기존의 폐쇄형 hollow 폐색장치 제작법의 단점들을 보완할 것이다.
