Objective was to study the characteristics of the indicators of the width of the dental arches of the lower jaw at the dolichomorphic form of the skull. Material and Methods. The morphometric parameters of the width of dental arches of the lower jaw have been studied. The work was performed on 28 preparations of skulls of people of both sexes of mature age with physiological occlusion of teeth and dolichomorphic form of the skull. The width of the dental arch was measured between canines, premolars and molars. Results. The maximum value of the width of the dental arch in both men and women was observed in the region of the second molars from the vestibular side. The minimum value of the investigated parameter was revealed in the region of canines on the palatal side. The indicator of the width of both the vestibular and lingual dental arches increased from the level of the canines to the molar level. Conclusion. A significant increase in the parameters of the width of the vestibular dental arch of the lower jaw in men over similar indicators in women was revealed only at the level of canines and first molars, and the parameters of the lingual dental arch only at the level of the second premolars.
