Error analysis of a magnetic jaw-tracking device.
This paper evaluates a new instrument for the analysis of jaw movements in three planes of space. The range of linearity, the saturation point, and the effect of the different positions of the magnet in relation to the sensors are presented. It is concluded that linear analysis of chewing movements via this system is reasonably adequate without major distortion, whereas linear analysis of maximal mandibular movements should be viewed with caution.
