Abstract

著者는 1973年 4月부터 1979年 6月 사이에 서울大學校齒科大學病院에 來院한 患者中에
서 顎關節異常을 呼訴하였고, 顎關節機能障碍로 診斷된 總 186名(男 93名, 女 93名)의 左右
側顎關節 X-線寫眞을 調査硏究한 結果 다음과 같은 結論을 얻었다.
1. 中心位咬合時顆頭와 下顎窩間의 거리 및 位置關係는 正常範圍位가 37.% 前方移動位가
37.3%, 後方移動位는 22.6%였다.
2. 2.5㎝開口時顆頭의 水平移動은 正常範圍位가 46.5, 前方移動位가 12.3%, 後方移動位가
41.1%였다.
3. 2.5㎝開口時兩側顆頭의 相互位置關係는 非對稱이 28.5% 對稱이 71.5%였다.
4. 中心位咬合時 및 2.5㎝開口時의 모든 計測値는 女子보다 男子가 컸으며, 顆頭의 水平
移動範圍에서, 男子는 過多運動, 女子는 過少運動이 많았다.

The purpose of this study was to investigate the radiographic images of Temporo-
mandibular joint trouble patients.
This study included 186 patients with the chief complaints of TMJ pain and
dysfunction.
Their age ranged from 17 to 68 years,
All patients were identified in the department of Dental Radiology at the Infirmary of
College of Dentistry, Seoul National University, during the period from Apr. 1978 to Jun.
1979.
The author has observed the radiographic variations of two positions of condylar head
taken by modified transcranial oblique-lateral projection, which are one in centric
occlusion and the other in 1 inch(2.54㎝) mouth open.
The results were obtained as follows;
1. In centric occlusion, the distances and positional relationship between the summit of
condylar head and the deepest point of articular fossa revealed more or less large
variations; Normal range is of 37.9%, anterior displacement of 37.3% and posterior
displacement of 22.6%.
2. In the horizontal movement of condylar heads when on 1 inch mouth open, it was
resealed that normal range was of 46.5%, anterior displacement of 12.3%, posterior
displacement of 41.1%.
3. In the positional interrelationship of both condylar heads when on 1 inch mouth
open, it was revealed that symmetry(71.5%) occurred approximately 2.5 times as many
as asymmetry.
4. In both centric occlusion and 1 inch mouth open, it was showed that almost all
estimated figures were greater in male than in female, an4 in the horizontal movement
of condylar head when on 1 inch open, it was stowed that hypermobility was dominant
in male and hypomobility in female.
