Abstract

We report 4 patients who developed change of occlusion which seemed to be related to anterior disc dislocation without reduction, but there was no distinct evidence of condylar destruction or collapse. They experienced sudden occurrence of occlusal change, anterior open bite in 2 patients, lateral CR-CO discrepancy in 1 patient, and anteroposterior CR-CO discrepancy in 1 patient. Also, this report is to find out if there is a relation between sudden occurrence of occlusal change and anterior disc dislocation without reduction.

교합이 완성된 성인에서 비정복성 관절원판전위가 있는 경우에 과두흡수가 없는 상태에서도 갑작스런 교합의 변화 즉 전치부 개교합이 발생한 환자 2명과 측방으로 중심위와 중심교합위 간 활주가 발생한 환자 1명과 그리고 전후방으로 중심위와 중심교합위 간의 차이가 발생한 1명의 환자를 관찰하였기에 증례 보고하는 바이며, 비정복성 관절원판전위와 연관되어 교합의 변화가 발생하는 원인을 분석하고자 한다.
