Abstract
Currently, experts have noted the need to search for new research methods based on the selection of the most stable anatomical landmarks for the graphic construction of dental arches of the milk bite and the assessment of their effectiveness in clinical practice. A retrospective biometric study of 27 pairs of plaster models of mammary bite jaws with their optimal functional occlusive relationships was carried out to develop diagnostic methods. Orthodontic treatment of 15 children with congenital pathology of the maxillofacial region was carried out by fixed arc equipment. Based on the analysis of biometrics, methods for the graphic construction of dental arches were developed. The first method was based on the laws of circle geometry (the prototype of the A.M. Schwarz method) and the calculation of the radius of the circle along its length (L = 2R). To the sum of the crowns of 10 milk teeth, the value of the diastem component (in our case, 9 mm) was added and the length of the semicircle was obtained, which was enough to divide by the number and get the magnitude of the radius of the circle. The effectiveness of treatment of children with unilateral cleft lip and alveolar process is shown. Analysis of dental arch biometric data showed that on the side of the cleft, the distance from the conditional sagittal to the milk canine was (11.52 0.93) mm before treatment, and after treatment, the studied parameter was (16.39 0.64) mm (p ˂ 0.05). On the cotrlateral side, the difference in the change in the position of the canine was not significant and in the dynamics of treatment changed from (14.93 0.79) mm to (16.27 0.84) mm (p ˃ 0.05). The diagonals of the dental arches (central-molar) on both sides after treatment were (35.52 1.13) mm. Thus, taking into account the data obtained, it was concluded that the graphic reproduction of the dental arch of the milk bite in the treatment of children with anomalies of the dental arches was made.
