초록

상악 총의치의 유지에 있어 후방 구개 폐쇄(Posterior palatal seal)의 역할은 중요하다. 최종 인상을 채득한 후 주모형상에 구를 형성하는 기계적 방법을 통하여 상악 의치에 추가적인 유지를 부여할 수 있으나 이는 임상적인 과정에서 간과되곤 한다. 그 결과 기공사에 의해 환자의 개별적 특성을 고려하지 않고 일률적인 방법으로 후방 구개 폐쇄가 형성된다. 현재까지 많은 이들에 의해 다양한 후방 구개 폐쇄 형태가 소개되어 왔다. 본 증례 보고는 환자의 해부학적 구개 형태 및 기능시 조직 변위를 고려한 후, 적절한 후방 구개 폐쇄의 위치 및 형태를 결정하여 상악 총의치를 제작하는 과정을 보고하는 바이다.

The role of the posterior palatal seal is important in retention of the maxillary complete denture. After taking the final impression, additional retention can be given to the maxillary denture through a mechanical method of forming a groove on master cast, but this is often overlooked in the clinical process. As a result, the posterior palatal seal is formed in a uniform way by the technician without considering the individual characteristics of the patient. Until now, various types of posterior palatal seal have been introduced by many people. This case report describes the process of manufacturing the maxillary complete denture by determining the position and form of an appropriate posterior palatal seal after considering the patient's anatomical palatal form and tissue displacement during function.
