Abstract

To fabricate removable partial denture which provide patient's comfort and maintain oral health, cast fabrication which reproduce anatomical and functional state of mouth is needed. Diagnostic cast and master cast are produced through the process of preliminary impression and final impression taking. Both of remaining teeth and edentulous area should be well taken in removable partial denture impression. According to the supporting type of partial denture, impression material and method can be changed. Therefore, understanding of impression procedure is essential for the accurate clinical application.

저작기능의 회복과 더불어 환자에게 편안함을 제공하며 잔존치아와 치조점막을 건강하게 유지할 수 있는 가철성 국소의치 제작을 위해서는 구강내의 형태적, 기능적 상태를 재현하는 모형제작이 필수적이다. 국소의치 제작을 위해서는 진단모형과 주모형의 제작이 필요하며 이를 위해서 예비인상과 최종인상 채득 과정을 거치게 된다. 국소의치의 인상채득은 고정성이나 총의치 인상과 다르게 치아부위와 조직부위 모두가 잘 인기되어야 하고 치아 결손 부위에 따라 교합을 지지하는 부위가 달라지므로 증례에 따른 적절한 인상재와 인상채득 방법에 대한 이해를 바탕으로 정확한 임상적 적용이 요구된다.
