The variability of the concept of «norm» in the structure of the dental system

Abstract
Facial aesthetics has always been a part of the political, economic, and cultural history of people around the world. Over time, it has become a real force of self-expression and a sign of social status. Modern studies emphasize the diversity of facial structure types, the shapes and sizes of dental arches, and the position of the incisors within the normal range. Contemporary scientific research confirms the relevance of searching for the boundary between physiological and pathological. The variability of normal structure leads to an expansion of the concept of ‘norm’ and a desire for the individualization of diagnostic data, making the study of normal variability in human structure a current task for modern science.
The aim of the study was to analyze the features of facial and skull structure in volunteers with normal dental occlusion. A photometric examination was conducted on 32 volunteers of Eastern European appearance, aged 18 to 25 years, with normal dental occlusion. Photometric and cephalometric studies were carried out. Statistically significant differences were found in volunteers with horizontal and neutral growth types in the vertical parameters of the lower jaw, lip position, incisor projection, mandibular ramus length, and the Garson index. Thus, the study shows that the facial structure with normal occlusion is variable and can have features that significantly exceed the normative or average values.
