摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, particularly to dentistry, and can be used for determining the facial skeleton growth type. Teleroentgenogram (TRG) in the lateral projection is used to construct a coordinate system through a tangential line to the upper edge of the external auditory canal and the lower edge of the orbit, and a line perpendicular thereto through the middle of the entrance to the Turkish saddle. Row of points on the skull TRG is determined in the lateral projection: or, n, ss, pg, gn, me, com, ram, go, co, se, icm, fn, ss', cc'. Following parameters are calculated: P1=(or-gn)×100/(ss'-cc')；P2=co(n-pg)×100/icm(n-se)； P3=or(co-go)×100/or(me-com)； P4=co(n-ss) × 100/fn(n-se), P5=ss(se-ram)×100/(fn(n-se)+fn(me-com)). When conditions 101≤P1≤119, 82≤P2≤94, 86≤P3≤95, 160≤P4≤180, 66≤P5≤75 are met, facial skeleton growth type is defined as neutral. When conditions P1<；101, P2>；94, P3>；95, P4>；180, P5>；75 are met, facial skeleton growth type is defined as horizontal. When conditions P1>；119, P2<；82, P3<；86, P4<；160, P5<；66, are met facial skeleton growth type is defined as vertical.EFFECT: method provides more accurate determination of facial skeleton growth type, which provides accurate diagnosis, further planning and forecast of orthodontic treatment.1 cl, 1 dwg, 3 tbl, 9 exИзобретение относится к медицине, в частности к стоматологии, и может быть использовано для определения типа роста лицевого скелета. По телерентгенограмме(ТРГ) в боковой проекции строят систему координат через касательную линию к верхнему краю наружного слухового прохода и нижнему краю орбиты, и перпендикулярную к ней линию через середину входа в турецкое седло. Определяют ряд точек на ТРГ черепа в боковой проекции: or, n, ss, pg, gn, me, com, ram, go, co, se, icm, fn, ss', cc'. Рассчитывают параметры: P1=(or-gn)×100/(ss'-cc')；P2=co(n-pg)×100/icm(n-se)； P3=or(co-go)×100/or(me-com)； P4=co(n-ss) × 100/fn(n-se), P5=ss(se-ram)×100/(fn(n-se)+fn(me-com
