Cephalometric studies of Ukrainian boys and girls with physiological bite by the method of Charles J. Burstone

Abstract

The analysis of scientific literature points to significant ethnic, racial, age and sexualdifferences in cephalometric indices obtained by the method of C. J. Burstone, whichnecessitates conducting similar cephalometric studies among different age and sexgroups of the population of Ukraine with physiological bite. The purpose of the study isto establish and analyze the cephalometric parameters by the method of C. J. Burstonein boys and girls of the Podillia region of Ukraine with orthognathic bite. Primary lateralteleroentgenograms of 38 boys and 55 girls with normal occlusion close to orthognathicbite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken fromthe data bank of the research center of the National Pirogov Memorial MedicalUniversity, Vinnytsya. Cephalometric measurements were performed according to therecommendations of C. J. Burstone. The statistical processing of the obtained resultswas carried out in the licensed package "Statistica 6.0" using nonparametric methodsfor evaluating the obtained results. When comparing the cephalometric parametersused in the analysis of C. J. Burstone between boys and girls with orthognathic bite inboys, the values of the following distances are significantly higher: Ar-Pt (PosteriorSection of Cranial Base), Pt-N (Anterior Section of Cranial Base), N-ANS (AnteriorUpper Facial Height), ANS-Gn (Anterior Lower Facial Height), PNS-N (Posterior UpperFacial Height), 1l-MP (Distance of Incisal Edge of 1L to Palatal Plane), 6u-NF (Distanceof Mesial Cusp of 6u to Palatal Plane), 6l-MP (Distance of Mesial Cusp of 6l toMandibular Plane), ANS-PNS (Maxillary Length), Ar-Go (Ramus Length), Go-Pog(Mandibular Length), B-Pog (distance from point Pog to point B, parallel to mandibularplane) and A-B (Distance of A to B on Occl. Plane); and in girls - only angle OP-HP(Angle of Occl. to Horizontal Plane). More than half of the cephalometric parametersobtained in the boys and girls of Podillia with orthognathic bite have reliable or tendencydifferences with the magnitude of the parameters given by C. J. Burstone, whichconfirms the need to establish their regional standards for correct use in Ukraine
