Incisal guiding table, for dental articulators, comprises a guiding block with a guiding surface in the form of a spiral staircase or a screw surface

摘要

Incisal guiding table fixed on the upper (1) or lower part of a dental articulator comprises a guiding surface (6) on which an incisal pin (5) is supported with a supporting force and which encloses an angle with a line of influence of the largest force component of the supporting force designated as the normal, corresponding to the angle of the protrusion or laterotrusion guide on a human set of teeth. The incisal pin in the movement simulation travels upon the predetermined guiding surface which is selected and positioned by rotating tilting, pivoting or displacing a guiding surface block (4) or by a combination of these processes. The guiding surface of the guiding block is in the form of a spiral staircase or a screw surface. The pitch of the spiral or screw surface is constant or non-constant, or the guiding surfaces are surfaces produced by numerous processes.
