A method for the automatic measurement of a tooth movement by means of a three-dimensional reverse engineering art

摘要

The present invention relates to a process for the automatic measurement of a tooth movement by means of a three-dimensional reverse - engineering - art; and, preferably, a method for the automatic measurement of a tooth movement by means of a three-dimensional reverse - engineering - art, with a tooth movement - measuring device is provided, with which it is possible, a movement status of the teeth before and after an orthodontic treatment by means of a spatial coordination of a three-dimensional digital model of a tooth to be measured. According to the invention, the tooth movement - measuring instrument two three-dimensional models, which extends in a function of the point in time can vary, and has a spatial coordinates to each model on. By the use of a technology, in which each model is superimposed on the tooth movement can be measured quantitatively and qualitatively. Furthermore, in accordance with the invention with the tooth movement - measuring instrument is possible, the tooth movement quantitatively and qualitatively measuring, in which by means of a laser beam scan spatial coordinates of a three-dimensional digital model to be employed, so that it is no longer necessary, a patient for measuring the movement of the teeth of a large amount of radiation, as shown in the case of the measurement by means of remote x-ray sides image analysis or tomography is the case, to expose the.
