THE RELATIONSHIP BETWEEN THE INDIVIDUAL GENETICALLY DETERMINED FACIAL PROFILE OF PATIENTS WITH A DISTAL OCCLUSION (ENGLE CLASS II) AND THE TYPE OF GROWTH OF THEIR FACIAL SKULL AND ROTATION

Distal occlusion (DO) is one of the most prevalent malocclusions in the sagittal plane, accounting for approximately 13 to 31.3% of all dentofacial anomalies. Currently, there are nearly 200 methods for analyzing lateral cephalometric radiographs, along with numerous supplementary techniques. Conducting a comparative analysis of cephalometric radiographs using the A.M. Schwarz and J. Jarabak methods allows for a more detailed diagnosis of distal occlusion and differentiation of its various forms. This approach not only facilitates a more objective diagnosis but also aids in formulating a rational treatment plan and predicting its prognosis. Purpose. Determining the Relationship Between the Individual Genetically Determined Facial Profile, the Type of Facial Skeletal Growth, and Its Rotation in Patients with Distal Occlusion (Class II According to Angle). Methods. To investigate the structural characteristics of the facial skeleton in patients with distal occlusion (Class II malocclusion according to Angle's classification) through cephalometric analysis. A comparative evaluation of cephalograms was conducted using the A.M. Schwarz method, in accordance with the facial skeletal growth types defined by J. Jarabak. Results. Our comparative analysis of the correspondence between the individual genetically determined facial profiles of patients with distal occlusion (Class II malocclusion) according to A.M. Schwarz, the types of facial skeletal growth, and its rotation as per J. Jarabak revealed the following patterns. In individuals with a horizontal growth type, medium faces with a forward-sloping chin predominated at 24.35%, and medium straight faces at 17.07%. Anteface with a forward-sloping chin was observed in 12.19%, and straight anteface in 14.63%. In the vertical growth type, retroface with a backward-sloping chin was most common at 22.22%, followed by anteface with a backward-sloping chin at 16.66%, and medium straight faces at 11.11%. In the neutral growth type, straight retroface predominated at 20.83%, retroface with a backwardsloping chin at 16.66%, medium faces with a forward-sloping chin at 20.83%, and medium straight faces at 20.83%. Notably, retroface with a forward-sloping chin was not observed in any type of facial skeletal growth. Conclusions. The comparative analysis of cephalometric radiographs (TRG) using the Schwarz and J. Jarabak methods has enabled a more detailed diagnosis of distal occlusion (Class II malocclusion) and the development of a comprehensive treatment algorithm with improved outcome prediction.
