A process for the preparation of multi-coloured dental restorations is described, in which glasses and glass ceramics with various compositions are given the shapes of dental restorations and colour changes are effected in the glasses and glass ceramics by irradiating them with artificial electromagnetic radiation and subjecting them to a heat treatment.

Method for manufacturing a multi-color dental restoration

A method for removing deposits in a print head of a 3D printer, including the steps of supplying (S) a liquid having a granular solid to the print head; and setting into vibration (S) the liquid in the print head.

Method for cleaning a print head

The present invention relates to a method for comparing three-dimensional dental structures, comprising the steps of acquiring (S) a target data set representing the shape and optical properties of a natural tooth; rendering (S) a digital tooth model () to generate an actual data set representing the shape and optical properties of the digital tooth model; determining (S) a first comparison value from the actual data set; determining (S) a second comparison value from the target data set; and determining (S) a deviation based on the first and second comparison values.

Comparison of color images of three-dimensional dental structures

The present invention relates to a method for fabricating a dental restoration, comprising the steps of rendering (S) a first digital tooth model with a first material combination for generating a first actual data set representing the optical properties of the first digital tooth model; determining (S) a first deviation between a target data set and the first actual data set; rendering (S) a second digital tooth model based on a second combination of materials to generate a second actual data set representing the optical properties of the second digital tooth model; determining (S) a second deviation between the target data set and the second actual data set; and fabricating (S) the dental restoration based on the first digital tooth model when the first deviation is less than the second deviation and fabricating the dental restoration based on the second digital tooth model when the second deviation is less than the first deviation.
