summary The aim was to investigate the relationship between the vertical craniofacial morphology and the sagittal path of mandibular movements. The study was carried out in 40 subjects who were free of temporo‐mandibular disorders. Mandibular movements and maximal jaw opening (MO) were recorded by means of a jaw tracking device. The opening–closing angle (OCA) was defined as the angle between the horizontal plane and the opening–closing path of movements. Vertical craniofacial morphology was assessed on prophile cephalograms by means of the Frankfort Mandibular Plane Angle (MP). The OCA did not differ between males and females ( P > 0·05). OCA and MP were negatively correlated ( r = −0·62; P < 0·001). MO was significantly greater in males that in females ( P < 0·05). MO was negatively correlated to MP (−0·44 < r < −0·49; P < 0·05). The findings suggest that the low‐angle subjects exhibit a more vertical path of the mandibular movements than that of high‐angle subjects. Differences in the sagittal path of jaw movements may be partly ascribed to anatomical factors.
