摘要

A method for the automatic measurement of a tooth movement by means of a three-dimensional reverse engineering art, with a device for the automatic measurement of the tooth movement by means of a three-dimensional reverse engineering art quantitatively a change in the position of a tooth with the use of a digital model by means of three-dimensional scanning, comprising the steps of:(a) by means of a 3 - dimensional scanning of data of an upper jaw and a lower jaw at a specific point in time, referred to below as a first point in time, and to a further point in time, referred to below as a second point in time, after the first time an appropriate three-dimensional model of the upper jaw and of the lower jaw in the first point in time, or in the second point in time is produced;(b) generating a three-dimensional model of an occlusion status in the first point in time, or in the second point in time, referred to below as an occlusion model of the upper jaw and of the lower jaw, in the first point in time and in the second time by means of an external occlusion the form of model of an upper jaw and a lower jaw, wherein the occlusion status..
