1.Biomehanika studying the mechanical properties and mechanical phenomena (see the Encyclopedic Dictionary of the USSR, Russia, France, Britain, Germany). 2.Ortoped dentist, along with medical education uses mechanical methods, is a branch of physics that is biomechanics. 3.Primenyayuschayasya currently in the CIS countries, the empirical method of relations tubercles chewing surfaces (1:1) There are over 100 years and does not ensure the stability of teeth in sick and elderly. Modern rational methodology developed by Siebert (2:1), Markskorsom (2:1), Gysi (2:1), Lehmann (2,5:1,5), Schwarz (5:3). 4.Vse foreign and local orthopedists in describing the construction of the occlusion did not indicate how You can get the load along the axis of the tooth root, which is essential for maintaining a balance of teeth (Sukharev, Kalvelis, severe, Hvatova, Olesova, Matveeva, Wolfle, Messermann, Dyment, Synge (1956 – 1997).
Resorting to the axioms of biomechanics, we have identified axial action of the force of chewing pressure and applied it in the method of 5:3. 5.Nagruzka affects the stability of lateral teeth (pressure in the transverse direction – Taptunova, Glasser): a) crushing the food (with 4 ramps), b) in the central occlusion (6-ramps), c) when swallowing food (with 2 central slopes). At various empirical and rational methods in swallowing food, when developing the greatest force, the last act in the side of the axes of the roots and only by the method of 5:3 – along the axes. 6.Sila – a vector with 3 parameters (magnitude, direction, point of application). At different inclinations of slopes (15-60 ) on the surface there is a need for chewing forces of the normal reaction – N and friction – F.
