The aim of this study was to determine whether T.M.J. tomographic examination
yielded significant differences in condyle positions among asymptomatic, myalgia,
derangement, and arthrosis groups of T.M.J. disorders.
The author obtained sagittal linear tomograms of right and left T.M.Js. of 36
asymptomatic, 22 myalgia, 54 derangement, and 31 arthrosis patients taken at serial
lateral, central, and medial sections in the intercuspal position after submentovertex
radiographs analyzed.
With the dual linear measurements of the posterior and anterior interarticular space,
condyle positions were mathematically expressed as proportion.
All data from these analysis was recorded and processed statistically,
The results were obtained as follows.
1. In asymptomatic group, radiographically concentric condyle position was found in
50.0% to 65.4% of subjects, with a substantial range of variability No significant
differences existed between men and women and also between right and left T.M.Js. for
condyle position.
2. In women, significant difference for mean condyle position of left lateral section of
each diagnostic category existed between derangement and myalgia groups (P<.05). Also
that of left central section existed between derangement and myalgia groups, and that of
left medial section existed between derangement and myalgia groups (P<.05).
3. In main-symptom side, condyle position in myalgia group was more concentric, and
condyle position in derangement group was more posterior. This showed significant
differences between derangement and myalgia groups in lateral, central, and medial
sections of main-symptom sides, and only between derangement and myalgia groups in
central section of contra-lateral sides (P<.05). Condyle position in arthrosis group was
broadly distributed among all positions.
4. In contra-lateral side, significant difference for mean condyle position of central
section of each symptomatic group existed between derangement and myalgia groups
(P<.05).
Condyle position in derangement group was more posterior. The distribution of the
condyle position of contra-lateral side in patients with unilateral symptoms was similar
to that of main-symptom side in each symptomatic group.
No significant difference existed between main-symptom and contra-lateral sides.
5. For internal derangement subgroups, condyle position in reducible disc displacement
group was more posterior than non-reciprocal and locking groups, but there was no
significant difference.
6. From 16 to 25 years, significant difference for mean condyle position of medial
section of main-symptom side of each symptomatic group existed between myalgia and
derangement groups (P<.05).
