초록

흡착 의치는 의치상연 주위 전체를 가동 점막으로 봉쇄하여 연하나 교합 시 의치상 내면에 일시적으로 음압을 형성하여 의치의 유지와 안정을 강화한다. 본 증례의 환자는 81세의 남자 환자로 새로운 의치를 제작하고 싶다는 주소로 내원하였다. 의치의 유지와 저작 효율에 대한 환자의 높은 요구도를 고려하여 흡착 의치를 통한 총의치 제작을 계획하였다. 하악 후구치 융기 부위를 가압하지 않은 채로 예비 인상을 채득 후 상하악 진단모형을 제작하였다. 이후 개인 트레이 제작 후 최종 인상 채득과 동시에 고딕 아치 기록을 시행하여 중심위 및 수직 고경을 채득하였으며, 상악에는 해부학적 치아, 하악에는 비해부학적 치아를 배열하여 설측 교합을 형성하였다. 이상과 같이 완전 무치악 환자에서 하악 흡착 의치를 통한 총의치 수복은 만족스러운 유지와 기능을 회복할 수 있었기에 본 증례를 보고하고자 한다.

Suction dentures enhance retention and support by forming negative pressure temporarily at the internal surface of denture base at times of swallowing and chewing because the areas surrounding the denture flanges are sealed by mobile mucosa. In this case, an 81-year-old male visited for new dentures. Considering the high expectations for retention and masticatory efficiency of dentures, fabricating complete dentures with suction dentures was planned. Preliminary impression was taken without applying pressure on retromolar pad area and diagnostic cast was fabricated. Afterwards, individual tray was made and final impression was taken, at the same time, gothic arch tracing was done to acquire centric relation and vertical dimension. Then, anatomic teeth were placed on maxilla and non-anatomic teeth were placed on mandible forming lingualized occlusion. Consequently, restoring a complete edentulous patient with complete dentures using mandibular suction denture resulted in recovering satisfying retention and function.
