Morphometric regularities of the depth indices of dental arches in the mesocrane skull type

Abstract

Objective: to reveal the morphometric regularities of the depth indices of the dental arches of the upper and lower jaws of the mesocrane skull type.Material and methods: the morphometric parameters of the depth of the dental arches of the upper and lower jaws were investigated. Te work was performed on 144 preparations of mesocrane skull type of people of both sexes of mature age with physiological occlusion of teeth. Te depth of the dental arch was measured from the point located at the center of the cutting edge of the medial incisor to the point of intersection with the line connecting the distal surfaces of the tooth crowns at the level of the canines, frst premolars, second premolars, frst molars, and second molars.Results: the range of confdence limits of the depth of the dental arches of the upper jaw in men at the level of canines and premolars surpassed those of women. Te range of confdence limits of the depth of the dental arches of the lower jaw in men and women at all levels of measurement was similar.Conclusions: the indices of the confdence limits of the depth of the vestibular and palatal dental arches of the upper and lower jaws are revealed. Te new data obtained as a result of the research, supplement and expand the information on the studied parameters, both in theoretical and clinical aspects.
