摘要：
FIELD: medicine.SUBSTANCE: parameters of cranio-facial complex, which include width of nose between protruding points on nose wings, equal segment AnAn, and distance between cheekbone points Zy-Zy, equal segment ZyZy, are measured in millimetres. After that the sum of mesio-distal dimensions of three teeth of frontal group canine, lateral and medial cutter, is also measured in millimetres. After that the sum from mesio-distal dimensions of seven teeth, including dimensions of three teeth of frontal group and four teeth of lateral group - first and second premolars, as well as first and second permanent molars is measured. After that, main parameters of dental arch are calculated: arch depth - Dd1-7 and Dd1-3, width - Wd7-7 and Wd3-3, frontal-distal diagonal - FDDd1-7 and FDDd1-3 are calculated by mathematical formulae. Segment AE, equal to depth of dental arch Dd1-7 is built. Segment AT is marked off on prolongation of line AE. Two straight lines - line E and line T are drawn through obtained points E and T perpendicularly to line AE. Twi segments, equal to half of the width of segment AT, are marked off on line E on both sides of point E, and segment KL, equal to dental arch width - Wd7-7 between second molars, is obtained. Segments AK and AL, equal to frontal-distal diagonal FDDdi_7, passing from frontal vestibular point to the level of location of second constant molars, are marked off from point A in both sides of arch. Circumference with radius AO is built on line AE through upper point A. Segments AC and AD, equal to frontal-distal diagonal of anterior part of FDDd1-3, are marked off from point A in both sides of arch. Points C and D are connected and segment CD, determining position of canines and corresponding to width between canines Wd3-3, is obtained. Point C is connected with point K, and point D is connected with point L with straight line. Lines from the middle of lines CK and DL and perpendicular to them to crossing with line T, and points M and N are
