초록
목적: 본 연구는 측두하악관절의 시상 CT 이미지에서 최대교두감합위시 양 과두의 위치와 대칭성을 평가하기 위해 기획되었다. 재료 및 방법: Cone-bem CT가 각 100명의 남/녀 그리고 증상/무증상으로 분류된 총 200명의 400개 측두하악관절을 평가하는데 사용되었다. 3명의 독립된 평가자(치과의사)가 전방위(AP), 중앙위(MP), 후방위(PP)으로 분류된 과두 위치와 양 과두의 대칭성을 결정하였다. 결과: 성별에 따른 전방위, 중앙위, 후방위의 평균 퍼센트(%)는 남성에서 48.5, 28.5, 23였고, 여성에서 34, 38, 28였다. 과두의 대칭성은 성별에 관계없이 대칭인 경우가 많았다. 증상과 무증상의 관점에서 보면 전방위, 중앙위, 후방위의 평균 퍼센트(%)는 무증상 그룹에서 44.5, 34, 21.5였고, 증상이 있는 그룹에서는 37, 33.5, 29.5였다. 과두의 대칭성은 무증상 그룹에서는 대칭성이 더 빈번했고, 증상 그룹에서는 비대칭이 더 많았다. 결론: 이 데이터는 Cone-bean CT에 의해서 얻어진 최대교두감합위에서 과두 위치의 임상 평가를 위해 유용한 기준이 될 수 있을 것으로 사료된다.
Abstract
Purpose: This investigation was designed to evaluate the condyle position and the symmetry of the both condyle heads at the maximum intercuspal position on the sagittal CT image of the temporomandibular joint. Materials and Methods: Cone-beam CT was used to assess 400 joints in 100 symptom and 100 symtom-free subject(100 male, 100 female). Three independent observers(dentists) determined the positions classified with Anterior Position(AP), Middle Position(MP), and Posterior Position(PP), and the symmetry of the both condyle. Results: According to gender, the mean percentages of AP, MP, and PP were 48.5, 28.5, and 23 in male group, and 34, 38, and 28 in female group. The symmetry of condylar heads was more common than asymmetry in the both of groups. In the respect of symptom or symptom-free, the mean percentages of AP, MP, and PP were 44.5, 34, and 21.5 in the symptom-free group, and 37, 33.5, and 29.5 in the symptom group. The symmetry of condylar heads was more common in the symptom-free group, but the asymmetry of condylar heads was more common in the symptom group. Conclusions: These data might serve as useful criteria for the clinical assessment of condyle position at the maximum intercuspal position optained by Cone-beam CT.
