23 Jul METHOD OF SELECTIVE GROUNDING OF TEETH
Abstract
FIELD: orthopedic stomatology. SUBSTANCE: before selective grounding, on occlusion surface of teeth of plaster models of jaws, coordinates of contact points of teeth are determined using occlusogram obtained in mouth cavity. Further, a plate of transparent material with perpendicularly arranged wire pin corresponding to tooth axis direction is pasted onto occlusive tooth surface, and, from difference of measured heights of occlusive contacts on plaster models and their projections on transparent plate, value of required grounding of hard tissue of teeth is determined with indispensable retention of three or more contacts on occlusive surface of side teeth and linear contact in the group of front teeth. Thus, plane perpendicular to tooth axis is formed in which contact points lie and create surface of occlusive contacts. EFFECT: eliminated horizontal and vertical constituents of chewing pressure.
