The author obtained individualized lateral cephalometric tomograms from 23 young
adults (46 of left and right normal TMJ) with normal occlusion and 20 patients (14 of
patient asymptomatic TMJ and 26 of patient symptomatic TMJ) with clicking and
painful TMJ after the analysis of submental vertex view.
Individualized lateral cephlometric tomogram analysis and TMJ space analysis were
performed after tracing each film.
All data from these analysis was recorded and statistically processed with CYBER
computer system.
The results were obtained as follows.
1. In submental vertex view, the mean condylar angulation of Rt. side in normal group
was 20.348¡£¡¾6.358¡£, Lt. side was 18.870¡£¡¾7.777¡£ and Rt. side in patient group was
19.350¡£¡¾ 7.576¡£, Lt. side was 17.750¡£¡¾6.146¡£ respectively
The mean condylar angulation of Rt. side was larger than Lt. side in normal and
patient group.
2. When the mandible was moved from centric occlusion to centric relation, condylar
position relating to the glenoid fossa was placed posteriorly and superiorly in normal
TMJ group and patient symptomatic TMJ group.
3. In centric relation position, the proportion of anterior space to posterior space was 1
593 for normal TMJ group, 1.604 for patient asymptomatic TMJ group and 1.671 for
patient symptomatic TMJ group.
In centric occlusion position, 1.390 for normal TMJ group, 1.539 for patient
asymptomatic TMJ group and 1.196 for patient symptomatic group.
4. Normal TMJ group, patient asymptomatic TMJ group and patient symptomatic TMJ
group and patient symptomatic TMJ group revealed significant differance in
2 measurement. (ANOVA-test, p<0.05)
5. Normal group and patient group revealed significant difference in Fh,
1 and 2 measurement. (T-test, p<0.05)
6. There were strong positive correlation (0.8771) between Fp and Fm, and strong
negative correlation (-0.9039) betr'eon 2 and 1 from the
lateral cephatometric tomogram analysis.
