Abstract

The aim of this paper was to claim or disclaim if the jaw movement differs significantly between right and left side among young physiological subjects. Relative displacement of the temporomandibular (TM) disc and the mandible during mouth opening was determined. The movement of the TM disc was studied using a magnetic resonance imaging (MRI) quasi-static scan sequence with a customized monodirectional “spreader” device. A number of sagittal static images in revolved sections of the temporomandibular joint (TMJ) were obtained in various positions of jaw opening from 0 to 50 mm. The results provided a description of the TM disc displacements as a function of jaw opening. The anatomical marker movement data was observed with the assumption of fixed skull. Motions of the TM disc and the mandible were found out. The maximum average displacements of the mandible and the TM disc were about 16 mm (x-direction) and 6 mm (mean value) respectively at mouth opening of 50 mm. The maximum average rotation of the mandible was 32°. While the movement of the mandible has already been published, though only for a small mouth opening, the behavior of the disc during the same movement has not been well depicted. The results of these measurements can be used for clinical diagnostics and also as inputs for finite element analysis (FEA).
