FIELD: medicine. ^ SUBSTANCE: invention relates to medicine, namely to dentistry, and is intended for determination of morphofunctional preservation of dentoalveolar apparatus. X-ray examination of patient is performed. X-ray image is used to determine degree of alveolus wall reduction around each tooth. Depending on reduction degree each tooth is assigned corresponding share of participation in chewing function DAA, determined with account of area of its root surface preserving normal contact with alveolus walls via ligamentous apparatus. If examined tooth is in contact with two teeth-antagonists, its share in chewing function is taken into account completely, if only with one - reduced twofold. If examined tooth has no contacts with teeth-antagonists or reduction of alveolus walls increases 3-d degree, its share of participation in realisation of chewing function is not taken into account. All shares of participation are summed up and morphofunctional preservation of DAA is evaluated in percent in comparison with the norm, taken as 100%. ^ EFFECT: method makes it possible to increase accuracy of static determination of morphofunctional preservation of DAA due to determination of share of participation of each separate tooth in chewing function. ^ 3 tbl, 1 ex |
