Failures Prosthetics and patient complaints arise, mainly due to lack of planning construction of dentures and the lack of accounting Moments and force vectors. Planning - this is not a treatment plan that is a sequence of stages, and application of biomechanical phenomena: - * normal force of reaction-N, - the friction force of a stingray - F, - force base reaction - Rn, - the reaction force of the tooth - R, - force moment, loosening a tooth - M. All these forces have direction as in the IKP, and in the RKP. Without their accounting construct a modern prosthesis is impossible because fundamental to assessing the quality of prosthetic treatment is to determine the direction of the forces of chewing stress in these positions, which is necessary to know the angle between these forces and axes of the teeth. It is known that the greatest force in the processing of food developed in the RKP.

Should therefore be the force (of direction) along the posterior teeth. Only account anatomical and physiological data for the system, that is more detailed, surveys are not sufficient. Torque (M) appears in each tooth with the action of a chewing load is the product of force and the distance between it and the center of resistance (c). M = N x L - under the influence forces on 1skat or M = R x L-at action forces the entire occlusal surface (Fig. 1). Fig. 1. For more specific information, check out Corey Ribotsky. Replacement of 2-power (N, F), acting on the food and the tooth, the first reaction force base (R).
