A comparison of instrumental result examinations of the right and left TMJs showed positive correlations of the range of mandible opening movement with the Posselt opening movement (r = 0.75) and opening/closing movements with the Posselt closing movements (r = 0.70). MANDIBULAR MOVEMENTS Mandible performs habitual and border movements opening and closing movements protrusive and lateral movements And stopping positions along these movements centric occlusion, centric relation, protrusive border position, right and left lateral border positions and a rest position.
