Median, or medial, points settle down according to a median-sagittal plane on a line which begins from border of a pilar part of a forehead, passes to a profile of the person and comes to an end with points basion and opistocranion.

Symmetrically in both sides from this median line points settle down lateral, or латеральные.

Distance measure by a special caliper or an anthropometer.

Table 4 the Form of the person depending on index number



Very narrow person

Index 93,0 and more

narrow person

Index 88,0-92,9

The person of average width

Index 84,0-87,9

wide person

Index 79,0 83,9

Very wide person

Index 78,9 and less

form of the person can be defined by means of a facial index beyond Izarom (IFM) - an index facial morphological.

Length of the person define from a point оph to gn, width of the person between zy - zy y mm.



size of an index 104 and more characterises the narrow person, from 97 to 103 — an average, 96 and less — the wide person.

Width of head define between points еурион; frontal - between the most convex frontotemporal points; malar - between points зигион; width between mandible angles - between points gonion.

In cases of small difference between these relations - the form of the person square, in cases of the big difference - oval.

For A. M. With Schwarz (1951) allocate 6 basic forms of the person: the round; the square; the six-sided; the oval; triangular with a basis referred upwards or downwards.

V.Ju.Kurljandsky (1958) distinguished the person square, cone-shaped - narrowed up in the form of a return cone. For convenience of definition of a face type the author recommended to press to the person of a ruler in a site tragus and mandible angles. The long and narrow person was characterised by an index - 90-94; wide and short-80-84; oval - 86-89,9.

In prescription for definition of proportionality of the person used "a golden section" principle. "Golden section" two parts of a piece in which the smaller part concerns to larger as big all a piece name. "Golden section" passes the person from a frontal point to the mental; in gnatic parts of facial department of a skull - from a nose end to a mental point passes for closed a mouth on a line labiums, for open is a distance equals to distance from a mental point to an upper lip. For "golden section" definition there are specially developed compasses which parts somehow size in the specified parities. "Golden section" define at studying of the person en face, and also in a profile.

Investigating a profile of the person, spend lines, study the linear and angle sizes; define the form of the person - direct, convex, bent.



For Angle spend a line of harmony from a point глабела to a point погонион. For ортогнатичного an occlusion it passes through a nose wing. Concerning this line the author has learnt a locating of a profile of the person, and also labiums in a frontback direction. For a photometry use a line which bridges a dermal point назион to a dermal point погонион for the aforementioned purpose. For definition of camber or ввігнутості persons on its pictures spend a perpendicular to a profile from a dermal point назион on the Frankfurt horizontal and continue it to the bottom border of the person; in addition spend a line from an orbital dermal point which answers bottom a contour of the osteal eye fossa, parallel to the first. The distance between these lines wears the name of "a biometric profile field of Drejfusa».

Fig. 3. A biometric profile field beyond Drejfusom.

Analyzing a face type and disturbances of its aesthetics, define a locating of a wing of a nose, a point субназион, a red bordering of the top and bottom labiums, and also a contour of a chin concerning these lines.

Schwarz recommended to bridge in a photometry a line (a stomatic tangent) points субназион and погонион and to measure size of a profile angle «Т», formed by this line and its crossing with a perpendicular to the Frankfurt horizontal, lowered with a dermal point назион (a nasal plane). This angle characterises a locating подносовой and mental points concerning a nasal plane, it use for definition of camber or concavity of the person. For angle sizes «Т», peer 10 °, - a profile of the bottom part of the person of a straight line, the most high-grade from the aesthetic point of view; for its sizes it is more 10 ° - the profile is cut back; for sizes it is less 10 - cut forward. In the latter case size of a profile angle designate a sign "-". Concerning a stomatic tangent define a locating of labiums: average — if the red bordering of an upper lip is crossed by this line and parted half-and-half and the line concerns a red bordering of a lower lip; Positive - if labiums are ahead from average position and negative - if labiums are for.

At studying of photos of a profile of the person the thickness of soft tissues, size of bones of a facial skeleton and their mutual relation cannot be considered. For more detailed studying of features of a structure of person A. M, Schwarz recommended to analyze the data of measurements of lateral teleroentgenograms of a head. Such research a thickness of soft tissues of the person define more precisely.

And divergences of the form of the person at children and at their parents define similarity by comparison of the form of the ranges drawn in photos of the person. Investigating the person en face, spend: a median plane of the person (ME); a tangent to a pilar part of brows from above to its crossing with a pilar part of head in a site of temples and bases of a tragus of auricles with points of angles of a mandible; tangents to mandible contours. If at the child of the person narrower, than in her parents, and crowns of teeths big average size it can serve one of indications to treatment with excision of separate teeths in the presence of dentoalveolar anomaly.

Investigating the person in a profile, spend lines which bridge points трагуса to points назион, орбитале, субназион, погонион, гонион. After that consistently bridge the named points. If at comparable forms of ranges en face and a profile at children and their parents tap narrower person at the child, than in her parents, anomalies of an occlusion and closer position of teeth in one or in both parents such disturbances eliminate after excision of separate teeth at the child taking into account an occlusion kind. It is important to compare also size of an angle of camber of the person, which образовывается at bond of points назион, субназион, погонион.
