Three Dimensional Analysis Of Jaw Movement During Free Chewing

We have also implemented a geometrical del of the jaw and a simple algorithm which allow the reconstruction of the psition of the pints solid dimensional chewing kinematic analysis based on to the dental arches (teeth an condyles) although small lightweight passive markers made solid with not visible to the Wcameras, as well as the jaw the dental arches by lightweight metal rods. The movement relative to the skull and the skull move- scene is surveied by the ELITE system, a Wsignal ments durinq chewing and rest. This paper presents a new approach for three processor that allows to achieve a high accuracy and reliability even in the very sm~ll volume (30 cubic centimeters) required by this analysis. In order to give the roaxirreun freedom of movement to the subject and to analyse the -pints of the man- dihla that are not visible a special delling procedure has been developed that allows the re- construction of whichever pint belonging to the mndibula during the different fUnCtiOM1 move- ments.
