Abstract

In the case of complete edentulous patients, as the mandibular alveolar bone absorption progresses, the maintenance and stability of the existing dentures, which had satisfactory functions in the past, are deteriorated. Despite of the need to fabricate new dentures, they often hesitate due to physical burdens on the duration and intensity of future treatment progress due to the effects of aging and systemic diseases. In the case of these completely edentulous patients, it is necessary to consider the treatment goals that can reduce the number of visits and the adaptation period for new dentures before starting the treatment. This case is a case of producing complete dentures of elderly patients with deteriorated physical ability. In addition to producing suction dentures through preliminary and definitive closed mouth functional impression suggested by Sato, CAD / CAM technique was used to transfer occlusal functional information of existing dentures to facilitate adaptation to new dentures.

완전무치악 환자의 경우 하악 치조골 흡수가 진행됨에 따라, 과거 만족스러운 기능을 보였던 기존 총의치의 유지 및 안정이 저하된다. 총의치 재제작이 요구됨에도 불구하고, 증령 및 전신질환 등의 영향으로 향후 겪어야 할 진료의 기간과 강도에 대한 신체적 부담으로 인해 새 의치의 제작을 주저하는 경우가 많다. 이러한 완전무치악 환자들의 경우에는 치료에 들어가기에 앞서, 내원의 횟수를 줄이면서, 새 의치에 대한 적응기간도 줄일 수 있는 치료목표 또한 함께 고려해야 할 필요성이 있다. 본 증례는 신체적 능력이 저하된 고령의 완전무치악 환자의 총의치 제작 증례로서, Sato가 제시한 예비 및 정밀 폐구기능인상을 통해 흡착식 의치를 제작함과 동시에, CAD/CAM을 활용하여 기존의치의 교합적 기능정보를 이전함으로써 새 의치에 대한 적응을 용이하도록 하였다.
