Method for producing a working model for dental purposes from a digitized impression

摘要

The present invention relates to a method for producing a working model for dental purposes from a digitized impression, in which an intraoral scanner is used to create a digital data set for displaying a model of an existing row of teeth (10) comprising a tooth stump (11) to be provided with a tooth crown, one separates the digital data concerning the tooth stump (11) from the data relating to the row of teeth (10) with the remaining teeth, one from the row of teeth with the remaining teeth without the tooth stump (11) on the basis of the digital data in the 3D Pressure created a real model, - based on the digital data concerning the tooth stump (11) this first virtual sits on a cone, - one of the placed on the cone tooth stump (11) based on the digital data in 3D printing a real Model created, which complemented in the region of the extracted tooth stump to the real model of the row of teeth (10) with the other teeth r is, - one fits the real model of the tooth stump (11) by means of the cone in the real model of the row of teeth (10) with the other teeth.Afterwards, on the tooth stump (11) a model of the tooth crown to be created, from the tooth crown is subsequently produced, whereby the model of the tooth crown is modeled on the basis of the complementary models of the row of teeth (10) and the tooth stump (11) so that the model of the tooth crown is in a precisely defined position in the model of the row of teeth (10). fits.
