A method for determining distal bite in children and adolescents with various degrees of severity of congenital collagenopathy

Today, congenital collagenopathy is a major problem in dentistry and medicine. At the same time, it manifests itself in various general and local phenotypic characteristics, which have a negative impact on the functional state of the organs and systems of the body. The aim of this study was to increase the effectiveness of the diagnosis of distal occlusion in children and adolescents with various degrees of severity of congenital collagenopathy based on the developed biometric measurements of the jaws. Materials and methods. A clinical and craniometric study of 1,207 children and adolescents with congenital collagenopathy aged 12 to 18 years was conducted. In the course of the study, distal bite was found in 584 schoolchildren. Results. The parameters of morphological deformities in the form of distal bite with various degrees of severity of congenital collagenopathy in children and adolescents was established. With a mild degree of distal bite, the distance along the cutting edges of the central incisors of the upper and lower jaw, according to the maximum and minimum values, varies from 3.02+0.04 to 5.61+0.03 mm, where the average value is 4.31+0.03 mm. With moderate severity, there are changes in indicators, the data of which are 5.91+0.05, 8.78+0.04 and 7.34+0.06 mm, and with severe severity – 9.01+0.24, 18.23+0.19 and 13.62+0.11 mm, respectively. The comparative analysis revealed significant differences in the biometric parameters of distal occlusion in congenital collagenopathy of mild and moderate severity, as well as in moderate and severe severity (p<0.05). Conclusions. The data obtained characterize that there is an established pattern associated with increased numerical values of the distal occlusion depending on the severity of congenital collagenopathy. At the same time, the established features of distal bite in various degrees of severity of congenital collagenopathy in children and adolescents have important theoretical, scientific and practical significance for improving their comprehensive medical and social rehabilitation and prevention. Based on the results of biometric measurements, the distal bite is determined, taking into account the severity of congenital collagenopathy in children and adolescents.
