WAY OF DIAGNOSTICS OF ANOMALIES OF DENTOALVEOLAR SYSTEM Russian patent published in 2009 - IPC A61B6/00 

FIELD: medicine.

SUBSTANCE: invention concerns medicine area, namely to stomatology and orthodontics and can be used at diagnostics and treatment of sagittal and vertical anomalies of an occlusion. Head teleroentgenograms are made in a lateral projection. Thus on teleroentgenograms the area of tongue and the area of space, free from tongue is determined. And the area of a sagittal tongue cut is defined as a contour formed by following points: a point of an end of tongue, the highest point on a back of the tongue, a point on an oral surface of tongue in a place of the greatest thickening of a soft palate; a point on a back surface of tongue in a place of the greatest narrowing of a stomatopharynx; the most acting point on a forward surface of a sublingual bone; point Me - the bottom point on the bottom contour of a body of the mandible in a place of applying of symphysis; an oral surface of an alveolar process of a mandible; a lingual surface and cutting edge of a crown of the central bottom incisor. And the area of space, free from tongue is defined as a contour formed by following surfaces and points: a palatal surface of the central incisor of the top jaw; a contour of the hard palate; an oral surface of a soft palate; a point on a back surface of tongue in a place of the greatest narrowing of a stomatopharynx; the most acting point on a forward surface of a sublingual bone; point Me the-bottom point on the bottom contour of a body of the mandible in a place of applying of a symphysis; an oral surface of an alveolar process of a mandible. The lingual surface and cutting edge of a crown of the central bottom incisor, space, free from tongue is defined between a back of the tongue and a contour of the hard palate. Then the areas of tongue and the area of space are calculated, free from tongue and on parities between the received parametres is diagnosed, at a parity of the area of space, free from tongue to the tongue area as 1:8 - distal and direct incisal occlusions or mesial and return incisal occlusions, and also a physiological occlusion in lateral department and deep incisal overlapping, and at their parity as from 1: 4 to 1: 3 - other kinds of anomalies of an occlusion.

EFFECT: way provides high accuracy and reliability of measurement, at the expense of its carrying out taking into account individual anatomic features of the patient, the way is distinguished also by speed and simplicity in its execution.
