Abstract
In order to obtain the basic data of movements of the mandible for diagnosis and prognosis determination of the T14j dysfunction, the author measured the ranges and shapes of movements of the mandible in the frontal, sagittal and horizontal trajectory with Saphon Visi Trainer GU (Tokyo Shizaisha Inc.) in 61 men.
The subjects who were undergraduate and graduate students of the School of Dentistry, Seoul National University (SNUr had no pain or symptoms of dysfunction of the masticatory system. The obtained results were as follows:
1. The mean for maximal right and leYt laterotrusion in the frontal trajectory were 11.3mm and 10.9mm, respectively and didn´t differ" significantly. Right and left latero-opening at 15mm, 25mm and 35mm mouth opening respectively didn´t differ significantly. Area of border movement of the mandible was 770.33mm2.
2. The mean for maximal protrusion in the sagittal trajectory was 10.2mm, antero-posterior deviation between ICP and RCP 1.2mm and angle of maximal protrusion and horizontal plane 20.5°.
3. The mean for right and left laterotrusion is 11.1mm & 11.2mm, respectively, and didn´t differ significantly.
