Abstract

著者는 放討線寫眞上으로 下顎顆頭의 骨變化가 認定된 顎關節障碍患者 31名의 顎關節 38
個에 對하여 세가지 放射線撮影法을 使用하여 硏究 분석한 結果 다음과 같은 結論을 얻었
다.
1. 硏究對象患者의 平均年齡은 31.7歲였으며 40歲以下가 24名(77.4%)으로 많았고 性差는
女性이 27名(87.1%), 男性이 4名(12.9%)로 여성이 많았다.
2. 세가지 撮影法 모두에서 骨變化를 認定할 수 있는 경우는 總38例中 19例(50.5%)였고,
Oblique lateral transcranial projection과 Orthopantomogram 모두에서 觀察不可能하였지만
Tomogram에서는 骨變化가 認定된 경우도 5례(13.2%)로 나타나서 Orthopantomo gram이나
Oblique lateral transcranial projection에서 觀察不可能했던 骨變化를 Tomogram을 通해
確認할 수 있었다.
3. 骨變化樣狀의 出現頻度는 Osteophyte가 가장 많았고 Flattening, Erosion, Concavity
의 順으로 나타났다.
4. 斷層撮影像에서 骨變化가 일어난 位置는 Lateral部位에서 31例(81.6%), Central部位에서
27例(77.4%)로써 Lateral 및 Central 部位에서 頻發하였다.
5. Oblique lateral transcranial projection과 Tomogram의 Lateral部位의 骨變化樣狀一致
率은 80.0%였고, Orthopantomogram과 Tomogram의 Lateral部位의 骨變化樣狀一致率은 76.9%였다.
#초록#
The author has studied radiographic bony changes of mandibular condyle head in
temporomandibular disorder patients using Oblique lateral transcranial projection,
Orthopantomography, and Tomography.
The bony change types and the frequencies of occurrence and the incidences of bony
changes in three different radiographic techniques were examined.
The coincidences of bony change types between the Oblique lateral transcranial
projection and the lateral part of Tomogram, the Orthopantomogram and the medial part
of Tomogram were also examined.
The results were as follows :
1. The mean age of patients was 31.7 years and under 40 years were 24 patients,
women were 27 patients, men were 4 patients.
2. The observable cases of bony changes in all three radiographic techniques were 19
cases(50%) of 38 cases and the observable cases of bony changes in only Tomography
were 5 cases(13.2%).
3. The most frequent radiographic bony change type was osteophyte and next orders
were flattening, erosion, concavity.
4. The positional incidences of bony change in Tomogram were 31 cases in lateral
part and 27 cases in central part.
5. The coincidence of bony change types between the Oblique lateral transcranial
projection and the lateral part of Tomogram was 80%, and the coincidence between the
Orthopantomogram and the medial part of Tomogram was 76.9%.
