ABSTRACT:
A method and apparatus for making a model of a set of teeth, in which each tooth is mounted on a holding pin (17) which is removably disposed in a base plate (15). For positioning of the holding pins, a datum plate (10) of transparent material is placed on the impression (5) of a jaw and the desired positions, of a respective holding pin for each tooth root, are marked. Then pins are inserted into a pre-perforated base plate (15) according to the markings, or a pre-perforated base plate of transparent material is used instead of the transparent datum plate (10), and is marked with desired pin positions on one side and provided with pins on its other side. The pins then penetrate molding material placed in the impression (5), and harden in place as the molding material hardens. The hardened molded material can then be sawed into separate parts.
