Abstract
通法의 顎關節撮影法으로 撮影된 顎關節症患者의 X線寫眞 134例를 對象으로 顎關節症患
者의 骨形態 異常과 顆頭位變化와의 相互關係를 調査하기 爲하여 骨形態異常이 있는 側과
顆頭位變化가 나타난 側과의 一致率, 骨形態異常 種類에 따른 顆頭位變化 出現率과 顆頭位
變化 出現時의 移動方向 等을 調査 檢討하여 다음과 같은 結論을 얻었다.
1) 骨形態異常이 있는 側과 顆頭位變化가 나타난 側과의 一致率은 52.65%였으며 調査한
7項中 5項에서 53% 以上의 一致率을 보여 骨形態異常과 顆頭位變化와는 相互密接한 關係를
보였다.
2) 骨形態異常種類別 顆頭位變化 出現率은 開閉口時 모두에서 骨皮質肥厚像과 骨表面 粗
造性時에 高率을 占하고 있어 比較的 初期의 顎關節症에도 顆頭位變化가 出現하였다.
3) 骨形態異常時의 顆頭位變化方向은 開口時에는 後方位 移動과 前方位 移動이 44.81%와
37.74%로 高率을 占하고 開口時에는 下方位 移動과 上方位 移動이 35.23%와 28.41%로 高率
을 占하고 있어 顎關節症 判讀 時의 指針이 되었다.
4) 骨形態異常 種類別 骨形態異常側과 顆頭位變化側과의 一致率은 骨皮質肥厚像에서
58.57%의 高率을 占하고 있어 比較的 初期의 顎關節症에서 一致率이 높았다.
#초록#
The author analysed the interrelation between the morphologic changes of bone
structures and the position of condylar head from the routine radiographs of 134 cases
of the temporomandibular joint arthrosis.
The frequencies of coincidence between the site of bone defrmity and condylar head
positional change were examined. Also, the positional changes of condylar head and the
direction of condylar movement in relation to the kind of bone deformities were
observed.
The results obtained were as follows ;
1. In 52.65 lier cent of total cases, the site , of positional change of condylar head
was coincided with the site of bone deformans.
The frequencies of the coincidence between these in the five items among seven items
examined were above 53 per cent. From the results, it seems that the positional changes
of condylar head were related with the morphological change of bone structure.
2. Eburnation and erosion revealed frequently positional changes in the opening and
closing position of the mouth, although in the early stages of the TMJ arthrosis.
3. In the bone deformans, during opine position of the mough 44.81 per cent of total
cases revealed backword movement and 37.74 per cent showed forward movement. In
closed position of the mouth, downward movement was revealed in 35.23 per cent of
total cases and upward movement 28.41 per cent of total cases.
4. In the cases showing eburnation, the frequencies of coincidence between the site of
positional change and bone deformans were 58.57 per cent of the total cases, that means
it was high in the early stages of the TMJ arthrosis.
