Abstract

The goal of suction denture is to enhance retention of dentures by the formation of negative pressure between the denture base and the underlying tissue and sealing around the denture by the mucosa. This patient has been converted to a completely edentulous state after the extraction of residual teeth. Fabrication of suction denture was planned because it was estimated that the conventional compete would be hard to achieve retention due to the absorption of residual ridge and lack of sublingual fold. Through appropriate clinical and laboratory technique such as preliminary impression on the mandibular rest position, provisional vertical dimension determination with Centric Tray® (Ivoclar Vivadent AG, Schaan, Liechtenstein), closed mouth definitive impression and jaw relation record using individual tray with Gnathometer M® (Ivoclar Vivadent AG, Schaan, Liechtenstein), artificial teeth arrangement considering stability of the denture, and proper polymerization technique that minimizes polymerization shrinkage, restoring the patient with suction denture resulted in satisfaction throughout the function and asesthetics.

흡착식 의치의 목표는 의치상과 하부 조직 사이의 음압 형성과 점막에 의한 의치 주변의 봉쇄에 의해서 의치의 유지를 강화하는 것이다. 본 환자는 잔존치 발거에 따라 완전무치악 상태로 전환하게 된 환자로, 잔존치조제의 흡수와 설하주름부의 부족으로 의치의 안정과 유지가 부족할 것으로 판단되어 하악 흡착식 의치 수복으로 보철계획을 수립하였다. 하악 안정위에서의 예비인상, Centric Tray® (Ivoclar Vivadent AG, Schaan, Liechtenstein)를 이용한 잠정적 수직고경 결정, Gnathometer M® (Ivoclar Vivadent AG, Schaan, Liechtenstein)이 부착된 개인트레이를 이용한 폐구정밀인상 및 악간관계 채득, 기능시 의치의 안정을 고려한 인공치 배열, 기능 및 심미를 고려한 연마면 형성, 중합수축을 최소화하여 의치상 내면적합도를 보전하는 의치상 중합 등의 임상 및 기공과정을 통해 기능 및 심미 전반에 걸쳐 만족스러운 하악 흡착식 의치로 수복하였기에 본 증례를 보고하고자 한다.
