METHOD AND DEVICE FOR DETERMINING LONGITUDINAL TOOTH AXIS Russian patent published in 2001 - IPC

Abstract RU 2169543 C2

FIELD: medicine. SUBSTANCE: method involves setting tooth model in perpendicular to the minimum image size when the model is tilted by means of optical system having telecentric beam path. To do it, device has base bearing an upright set in perpendicular to it. The upright carries cantilever movable in vertical and azimuthal direction bearing the optical system with built-in scale grid. The optical system axis is in perpendicular relation to the base plane. EFFECT: enhanced accuracy of operation. 1 dwg
