Abstract

著者는 顎關節機能障碍息者總 78名(男子 26名, 女子 52名)을 對象으로
Transcranial-oblique lateral 撮影法으로 撮影한 後顎關節機能障碍의 主症狀인 關節雜音,
顎關節疼痛, 關口障碍의 症狀에 따라 中心咬合時顎關節腔間隔, 2.54㎝開口詩下顎顆頭의
水平移動距離 및 關節隆起와의 前後方關係를 調奎하여 다음과 같은 結論을 얻었다.
1. 顎關節障碍患者群에서 前方과 後方顎關節腔間隔은 減少하였으나 有意性은 없었으며 上
方顎關節腔間隔은 有意性 있는 減少(P<0.01)를 보였다.
2. 2.54㎝開口時下顎顆頭의 水平移動距離 및 關節隆起와의 前後方關係는 顎關節障碍患者
群에서 罹患側과 健全側 모두 有意性 있는 滅少(P<0.01)를 보였다.
3. 顎關節障碍患者群에서 下顎顆頭의 移動距離는 罹患側에 比해 滅少하였다.
#초록#
The author obtained the transcranial-oblique lateral radiograms from 78 patients (26
male, 52 female) with temporomandibular dysfunction problem.
And then, the author analyzed the dimensional changes of the TMJ space on centric
occlusion, horizontal condylar movement and antero-posterior positional relationship of
condyle to the articular eminence on 2.54 ㎝ mouth opening with clicking, TMJ pain and
mouth opening limitation repectively, which were the symptoms of the
temporomandibular joint pain dysfunction problem, and compared these data with control
group.
The results were as follows:
1. In centric occlusion, anterior and posterior TMJ space of experimental group was
slightly lesser than those of the control group, also superior TMJ space of experimental
group was significantly lesser than that of the control group.(P<0.01)
2. In 2.54 ㎝ mouth opening, the condylar horizontal movement and the
antero-posterior positional relationship to the articular eminence were significantly lesser
than those of the control group.(P<0.01)
3. Examined experimental group, the degree of condylar horizontal movement of
affected ids was lesser than that of the normal side in 2.54 ㎝ mouth opening.
