抄録

In a previous study, it was confirmed that the head moves rhythmically and coordinately with jaw tapping movements. However, this report only referred to the vertical movements of the upper incisal point as mandibular movement. If the head moves in order to maintain balance during jaw functional movement as reported, it is expected that the upper incisal point moves not only vertically but also anteroposteriorly. The objective of the study was to assess the anteroposterior component of the head movement in order to clarify the existence of cooperated head and mandibular movement during jaw tapping. The experimental method followed in previous studies was repeated to analyze data from five young adults with the same six-degree-of-freedom measuring device.<BR>The upper incisal points moved rhythmically anteroposteriorly, as reported for the vertical direction. The amplitude of anteroposterior motion of the upper incisal point was about 8.6% of the mandibular range of motion. The upper incisal point moved anterosuperiorly during opening and posteroinferiorly during closing. As the mandibular range of motion became greater, the amplitude of anteroposterior motion of the upper incisal point became greater. The results suggested that the vectors of head movement translation depends on the magnitude of mandibular range of motion.
