The analysis of the angular parameters of telerentgenograms aimed at determining the typological variants o the facial region of the head is still relevant and requires additions and improvements. Goal. To conduct a comparative analysis of various methods for determining the types of facial growth, including author's additions, in the physiology and pathology of occlusion on a telerentgenogram in lateral projection. Materials and methods. The retrospective study included the analysis of 46 telerentgenograms with physiological occlusion and 23 images with dental-alveolar and gnatic malocclusion. Traditional research methods were used in the analysis. The parameters of the total Bjork angle, the Ricketts facial angle, the lower gonial angle, and the angles determining the position of the mandibular plane to the base of the skull and the base of the upper jaw were determined. The analysis used a generally accepted sectoral chart of the types of facial head growth. Results and discussion. The total Bjork angle was (389.47 ± 1.46)°. The lower gonial angle was (71.26 ± 1.39)°. The facial angle of Ricketts in the whole group was (90.69 ± 0.72)°. The angle NSL-ML was (29.13 ± 1.28) degrees, and the angle NL-ML was (24.41 ± 1.64)°. All parameters were close to the neutral type of growth, however, significant variability of signs was determined. It was noted that the variability of the Bjork angle was usually determined by the magnitude of the mandibular angle, which varied from 110 to 128° during physiological occlusion. The results of the study made it possible to amend the data of the sectoral analysis of facial growth types and conduct a comparative study with generally accepted indicators. Conclusion. An analytical review of methods for assessing the typological features of a face allowed us to modify the sector diagram, which amended the ranges of variability of features and highlighted indicators of physiological and pathological variants of the type of facial growth. The proposed diagram can be used by orthodontists and maxillofacial surgeons when planning the treatment of occlusion anomalies associated with changes in the vertical parameters of the face and its main divisions.
