Abstract:
The use of cephalometric analysis of lateral teleroentgenograms allows orthodontists, maxillofacial surgeons and other related specialists to organize a patient's treatment plan.However, for the full application of this method, it is necessary to determine in advancewhich indicators for it can be considered the norm, and which are already a pathology. Thepurpose of the study is to establish the peculiarities of cephalometric parameters accordingto the COGS method, related to the profile of the soft tissues of the face, in Ukrainian youngmen and young women with an orthognathic bite with different facial types. 46 young menand 72 young women who belonged to the residents of Ukraine of the Caucasian race inthree generations and had an orthognathic bite were subjected to cephalometry accordingto the COGS method of indicators related to the profile of the soft tissues of the face. Theface type was determined according to Garson's morphological index. Statistical processingof the obtained results was carried out in the license package "Statistica 6.0" using non-parametric estimation methods. Among Ukrainian young women with different types offaces, the following reliable or trends of differences in teleroentgenometric indicatorsrelated to the profile of soft tissues of the face according to the COGS method wereestablished: young women with a very wide face have smaller values of the Gl'-Sn-Pog'angle and the Sn-Gn'/H-Gn' ratio (compared to the middle and narrow faces) and the angleCotg-Sn-Ls and the distance Ls-(Sn-Pog') (compared to the middle face); young womenwith a wide face have larger values of the Ls-(Sn-Pog') distance and smaller values of theStms-I distance (compared to the average face type); women with a narrow face have largervalues of the Gl'-Sn distance and the Gl'-Sn/Sn-Me' ratio (compared to the medium face),the Sn-Gn'/H-Gn' ratio (compared to the wide face) and smaller values of the distance Sm-(Li-Pog') (compared to the wide face). Among Ukrainian young men with different types offaces, following reliable or trends of differences in teleroentgenometric indicatorsrelated to the profile of soft tissues of the face according to the COGS method wereestablished: representatives with a very wide face have larger values of the Gl'-Pog' distance (compared to an average face) and smaller values of Sn-Gn'/H-Gn' ratio and Stms-Idistance (compared to the average face); representatives with a wide face have largervalues of the Sn-Stms/Stmi-Me ratio (compared to the average face) and smaller values ofthe Gl'-Sn/Sn-Me' ratio (compared to the average face); representatives with a narrow facehave larger values of the Gl'-Sn/Sn-Me' ratio (compared to very wide and wide faces). Minormanifestations of sexual dimorphism of cephalometric parameters determined by theCOGS method related to the profile of the soft tissues of the face were also establishedbetween young men and young women with different facial types.
