Comparative Characteristic of the Maxillary Dental Arch Width Indicators Variability in Men with Different Craniotypes

The study of of dental arches morphology is relevant for the improvement and development of new diagnostic and surgical methods. The aim is to make a comparative evaluation of the dental arches width on the upper jaw in mature aged men with physiological occlusion depending on the craniotype. Material and methods. The morphometric parameters of the maxillary dental arches’ width have been studied. The work was performed on 172 preparations of mature aged male skulls with physiological occlusion of teeth. The cranial index was defined as the ratio of the transverse dimension of neurocranium to its longitudinal dimension. When examining dental arches, the main points were set on the medial and distal corners of the tooth crowns from the vestibular and palatal sides. The width of the maxillary dental arch was measured between canines, premolars and molars. Results. The values of the width indices of both the vestibular and palatal sides of the maxillary dental arches at all levels of measurement prevail in the brachycranial type of the skull. The indicators of the maxillary dental arches width in mesocranes are more then those in dolichocranes only at canines and the first premolars. At the second premolars and molars, the difference in the average statistical parameters of the width of the dental arches was not observed. Conclusions. The width of maxillary dental arches in men of mature age depends on craniotype. The new data obtained as a result of the research, supplement and expand the information on the studied parameters, both in theoretical and clinical aspects.
