Claims (2)

1. Способ определения продольной оси зуба, включающий определение базового ориентира для фиксации рабочей модели в пространстве, отличающийся тем, что, с целью повышения точности определения продольной оси зуба, его модель, установленную на шарнирном столике, помещают под оптическую систему на линию ее оптической оси и выбирают такой наклон модели, при котором площадь изображения поверхности зуба во время его обзора через оптическую систему станет минимальной.1. The method of determining the longitudinal axis of the tooth, including determining a reference point for fixing the working model in space, characterized in that, in order to improve the accuracy of determining the longitudinal axis of the tooth, its model mounted on a hinged table is placed under the optical system on the line of its optical axis and choose a model tilt such that the image area of the tooth surface during its review through the optical system becomes minimal. 2. Устройство, содержащее основание, на котором закреплена стойка с кронштейном, несущим разметчик линии выпуклости или иной рабочий инструмент, ориентированный перпендикулярно рабочей плоскости основания, и столик со средствами его двухосного крепления, отличающееся тем, что, с целью повышения точности определения продольной оси зуба, устройство снабжено оптической системой с телецентричным ходом лучей, причем оптическая ось этой системы перпендикулярна рабочей плоскости основания. 2. A device containing a base on which a stand is mounted with a bracket carrying a convex line marker or other working tool oriented perpendicular to the working plane of the base, and a table with means of its biaxial fastening, characterized in that, in order to increase the accuracy of determining the longitudinal axis of the tooth , the device is equipped with an optical system with a telecentric path of the rays, and the optical axis of this system is perpendicular to the working plane of the base.
