Measuring teeth in three dimensions, especially for making dental protheses or dental treatment work, uses optical measurement of spatial positions of dental impression

摘要

A dental impression is taken using an impression and holder device, especially a face arch and/or articulator, then the impression and its spatial position is measured optically and converted into three-dimensional coordinates, and these coordinates are used for dental work or treatment. An Independent claim is also included for the device used to carry out this method.
