A relationship between the degree of activity zones of tension, the direction of the applied load and the condition of the bone tissue of the alveolar process. Calculated data confirming the absoute vaues of the indicators of stresses and displacements dentition segment elements. The magnitude of alternating stress and displacement elements in various areas of human dentoalveolar apparatus depends on the strenght and direction of load, as well as the bone density of alveolar bone.
