Abstract

Long-term use of inappropriate prosthesis often results in habitual closure or irregular mandibular movements. In that case, guide to the stable centric position is difficult. Therefore, by using a treatment denture, the muscles and TMJ should be stabilized and the jaw relation should be acquired with the treatment position. Compared to the conventional method, digital technology in fabrication complete denture has the advantage of reproducing a stable tooth arrangement in cases of difficult tooth alignment, minimizing laboratory errors and reducing denture fabrication time. Therefore, in this case, the final denture was fabricated by digitally reproducing the stable treatment position, vertical dimension, and lip support with a treatment denture, and satisfactory results were obtained.

부적합한 보철물을 장기간 사용하면 습관성 폐구위나 불규칙한 하악 운동을 보이는 경우가 빈발하다. 이러한 환자는 고정된 중심 위로 유도하는 것이 어려우므로 치료의치를 이용하여 근육과 TMJ를 안정 시키고 치료위로써 악간 관계 채득을 해야한다. 디지털 방식을 이용한 의치 제작은 전통적인 방식과 비교하여 치아 배열이 까다로운 증례에서 안정화된 치아 배열을 재현하여 수작업에 의한 오차를 최소로 하고, 의치 제작 시간을 감소 시킬 수 있다는 장점이 있다. 따라서 본 증례에서는 치료의치로 안정된 치료위, 수직고경 및 구순 지지도를 디지털 방식으로 이행하여 최종 의치를 제작하였으며, 만족스러운 결과를 얻었기에 이를 보고하는 바이다.
