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 per-formed after tracing each film.
All data from these analysis was recorded and statistically processed with CYBER computer system.
The results were obtained as fellows.
1. In submental vertex view, the mean condylar angulation of Rt. side in normal group was 20.348°±6.358°, Lt. side was 18.870°±7.777° and Rt. side in patient group was 19.350°±7.576°, Lt. side was 17.750°±6.146° 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, 1.370 for
normal TMJ group, 1.539 for patient asymptomatic TMJ group and 1.176 for patient symptomatic group.
4. Normal TMJ group, patient asymptomatic TMS group and patient symptomatic TMJ group and patient symptomatic TMJ group revealed significant difference in ∠C^^2 measurement.(ANOVA-tet, p<0.05)
5. Normal group and patient group revealed significant difference in Fh, ∠C^^1 and ∠C^^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) belween ∠C^^2 and ∠C^^1 from the lateral cephalometric tomogram analysis.
