On the basis of cranio-, gnato, and profilometric studies, the average angular and linear measurements of teleroentgenograms were calculated for each age group of patients, with which the average data of the age norm were compared. It was found that in the period of milk bite, dentoalveolar forms of progeny prevail. In a removable and especially permanent bite, there is a violation of the proportionality of the ratio of the upper and lower jaws and a sharp discrepancy between the length of the body and the height of the branches of the lower jaw, that is, the signs of progeny increase.</span></span></p>progenyteleroentgenogramKazan Medical archivпрогениятелерентгенограммаКазанский медицинский архив[Демнер Л.
