Abstract

Soft liner is used to functional impression technique when dental stone is immediately poured after taking impression because of viscoelasticity. In this case, a 78-year-old male visited for new dentures. Due to severe resorption of mandibular edentulous ridge, functional impression taking by closed mouth technique was planned. First of all, making maxillary and mandibular provisional dentures was done, and lined by soft liner to rehabilitate pressured maxillary and mandibular edentulous ridge. After this, Functional impression was taken by closed mouth technique using provisional dentures which are transformed to healed maxillary and mandibular edentulous ridge, and final denture were fabricated using maxillary provisional denture as a reference of artificial teeth arrangement. Consequently, restoring a complete edentulous patient with taking functional impression using provisional dentures resulted in recovering satisfying retention and function.

연성 이장재는 점탄성적 특수성으로 인하여 인상 채득 후 바로 치과용 경석고를 주입할 시, 기능 인상에 사용할 수 있다. 본 증례는 78세의 남성으로 새로운 의치를 제작하고 싶다는 주소로 내원하였다. 하악 치조제의 심한 흡수로 인하여, 폐구법을 통한 기능 인상을 채득하기로 계획하였다. 먼저, 상, 하악 임시 의치의 제작을 시행하고, 연성 이장재를 내면에 도포하여 압박된 상, 하악 무치악 치조제의 치유를 유도하였다. 이후, 회복된 상, 하악 치조제에 맞게 내면이 변형된 상, 하악 임시 의치를 이용하여 폐구법을 통한 기능 인상을 채득하였으며, 상악 임시 의치의 치아 배열을 참고하여 최종 의치를 제작하였다. 이상과 같이 완전 무치악 환자에서 임시 의치를 이용하여 기능 인상을 채득하여 만족스러운 유지와 기능을 회복할 수 있었기에 본 증례를 보고하고자 한다.
