Normal stresses, tangents stresses along forming and directing to a surface of the periodontal shell arising at action on a fang of concentrated force are defined. The geometrical form of a periodontium is described by the equations of elliptic hyperboloids. Calculations and visualisation of fields of stresses are executed for two abundant clinical cases of action of loading on single-fang premolar and a canine.
