Objective: The study was to reveal the interrelations of the dental arch widths of the upper jaw with certain linear parameters of the facial section of the mesocranial skull type.
Methods: The work was performed on 144 preparations of skulls of people of mature age of both sexes with physiological occlusion of teeth. The following parameters of the facial part of the skull were studied: the upper face height, the face width, the height of the dental alveolar part of the maxilla, the height of the intergnatic part. The width of the dental arch was measured between canines, premolars and molars.
Results: As a result of the study, the minimum and maximum confidence limits for the widths of the dental arches at different levels of measurement, as well as the parameters of the facial part of the skull, were determined. The range of these boundaries is set. It was revealed that the parameters of the upper face height, face width in men and women significantly exceed over similar indicators of vestibular dental arches at all levels of measurement. The height of the intergnatic part of the facial part of the skull was less than the width of the dental arches in men only.
Conclusions: Thus, the width of the vestibular and palatal dental arches is less than the width of the face, but exceeds the height of the dental alveolar part at all levels of measurement. The index of the width of the vestibular dental arch in the region of the canines is less than the upper height of the face and the intergnatic part. When approaching the distal parts of the dental arch, an inverse relationship is observed. In this case, the palatal denture width is less than the face data at all measurement levels. The obtained data showed the interrelation of the width of the dental arches of persons of mature age with the parameters of the facial part of the skull. However, sex differences are poorly expressed.
