Abstract

This study was made to analyze the positional relationship of mandible to hinge axis in normal subject as the diagnostic criteria of T. -N1. J. dysfunction. The author has conducted the study using the Cephalometric P-A view, and dental of 53 males and 51 females. By measurement, the standard value of cranio-facial and occlusal asymmetry in normal subject obtained.
The following results were obtained
1. Although the degree of the difference between right and left width in each measured line was small, asymmetry in normal subject could be identifed.
2. In male, measurement between genial tubercle and hinge axis is 127.20±6.06^(㎜) in left, 125.83±6.25^(㎜) in right, and angle between genial tubercle and hinge axis is 48.48±3.53˚ in left, 49.58±3.72˚ in right. In female, measurement is 119.32±5.81^(㎜) in left, 118.82±5.35^(㎜) in right anu angle is 48.06±2.15˚ in left, 48.17±2.31˚ in left, 48.17±2.31˚ in right.
3. In male, difference between left and right canine cusp tip of maxilla about X-bar is 0.70±0.59^(㎜), and that of central pit of first molar of maxilla is 0.98±0.75^(㎜). In female, difference is 0.64±0.52^(㎜) in canine and 0.92±0.76^(㎜) in molar.
