Modeling of individual teleradiographic indicators according to the Steiner method for Ukrainian young men with wide and young women with a very wide and wide face types
Cephalometric methods of analysis of lateral teleradiograms are one of the key elements of orthodontic planning of treatment of a patient with pathology of the dental-jaw system. Determining normative teleradiographic indicators for the local population is a key step for the successful application of one or another method of analysis, in particular, for Ukraine. The aim of the study was to construct and analyze regression models of teleradiographic parameters used in the Steiner method for Ukrainian young men and young women with orthognathic occlusion with different face types. 49 young men and 76 young women with orthognathic occlusion in the software OnyxCeph³™, version 3DPro, the company Image Instruments GmbH, Germany (license № URSQ-1799) conducted a cephalometric study using the Steiner method. The division into facial types was performed using the Garson index. Cephalometric parameters were divided into three groups: the first – indicators used in cephalometric analyzes of Schwarz, Ricketts, Steiner, Roth-Jarabak, Burstone and Bjork and are included in the parameters that usually do not change during surgical and orthodontic treatment; the second – dental-maxillary characteristics according to the Steiner method which surgical methods can be used to change the length, width, angles and position of the jaws; third – indicators according to the Steiner method that characterize the position of each tooth relative to each other, cranial structures and the profile of the soft tissues of the face. Modeling of individual teleradiographic indicators was performed in the licensed package “Statistica 6.0” using step-by-step regression analysis. When analyzing reliable models of teleradiographic indicators according to the Steiner method, which were included in the second group depending on the indicators of the first group with a coefficient of determination higher than 0.6, it was found that out of 7 possible, 5 models were built for young men with a wide face type, which most often include the value of the distances Ar-Go and N-S and the angles H and N-S-Ar; young women with a very wide type of face – 3 models (R²=from 0.604 to 0.812) which most often include the value of the angles N-S-Ar and H; in young women with a wide type of face – 4 models (R²= from 0.694 to 0.771) which most often include the value of the angles POr-NBa and H, the distance P-PTV and the ratio S-ar:ar-Go. When analyzing reliable models of teleradiographic indicators according to the Steiner method, which were included in the third group depending on the indicators of the first and second groups with a coefficient of determination higher than 0.6, it was found that out of 8 possible in young people with a wide face type, 7 models were built (R²= from 0.662 to 0.946). which most often include the magnitude of the angles ANB and SN-GoGn and the distance P-PTV; in young women with a very wide face type – 4 models (R²= from 0.635 to 0.844) which most often include the value of the angles ANB, SNA, POr-NBa and the distance Pog-NB; in young women with a wide type of face – 6 models (R²= from 0.617 to 0.923), which most often include the value of the distances Pog-NB and N-CC and the angle ANB. Construction of regression models of teleradiographic indicators used in the Steiner method in Ukrainian young men and young women with orthognathic occlusion is the foundation for creating a database of normative cephalometric indicators in Ukraine, which will provide dental care to the population at the current level.
