 note = {P(論文), This study was carried out to find out whether the mandibular position during pronunciation of Japanese syllable is effective in the determination of the vertical dimension. The stability of the mandibular positions during pronunciation of the Japanese /ashi/, /achu/, /aji/, /esu/ and the relationship between each position and the rest position were examined in 64 subjects (male : 31, female : 33). Each subject had a complete natural dentition with no marked occlusal abnormalities. The subjects were seated in an upright position without a head rest. Mandibular movements during pronunciation were recorded five times for the interocclusal distance in the vertical direction using the sirognathograph analyzing system. The vertical dimension was measured at the stable point of the position in pronunciation and the rest position. In order to clarify the stability of these mandibular positions, the interocclusal distance and coefficient of variation (CV) were calculated. The CV value of the mandibular position during pronunciation was smaller than that of the rest position, and the mandibular position during /esu/ phonation showed the smallest value in CV. The vertical dimension during /esu/ phonation approximated to that of the rest position. Thus, the results suggest that the mandibular position during the pronunciation of the Japanese syllables (/esu/) was effective in the determination of the vertical dimension in the clinical treatment.},
