Abstract
In this study, we measured jaw movement of female volunteers who did not exhibit any symptoms of temporomandibular joint dysfunction using a new jaw tracking device using two magnetic fields in quadrature phase.We compared the diagnostic parameters of females whith those of males which ware reported in a previous study.
Furthermore, we considered the characteristics of a new jaw tracking device.
1. The parameters which related to range of the border movement showed significant difference due to the physical proportions between males and females.
2. The parameters which related to excursive movements did not show significant difference between males and females.
3. The parameters which related to habitual mouth opening show significant difference due to the measurement error between males and females.We must improve the new jaw tracking device.
