Functional Parameters of the Facial Part of the Upper Jaw in Children During the Period of Replacement Bite

Relevance of the study. The size of the upper incisors is the starting point of textbook methods of biometric diagnosis of dental arch anomalies in various periods of ontogenesis. The sum of the width of the crown parts determines the width of the dental arches between the premolars and the first molars of the permanent bite. The difference in the numerical values of the coefficients proposed by the authors determines their limited use, taking into account the typological features of the upper dental arches, even with physiological occlusion.
