AI Technical Summary

Benefits of technology

The present technology describes methods for creating denture replacements on teeth without damaging them during treatment. This results from how well they are designed when compared against existing prosthetics made up entirely of artificial materials like plaster castings. By describing this irregularity, it becomes easier to make these prostheses while maintain their effectiveness over time due to its ability to match natural edges accurately.

Problems solved by technology

The technical problem addressed during this process for accurately inserting or positioning teeth on prosthetics made from ceramic materials has been caused by incorrect placement of these digital models used with computer-aided design (CAD) methods such as 3D printing techniques.

Embodiment Construction

[0022] figure 1 A block diagram showing a method for manufacturing an oral restoration. In step S101, the reference geometry for the blank is imported as a CAM dataset into a dental CAD dataset giving the spatial shape of the oral restoration. The CAM data set describes, for example, the circumference and height of the disk of the blank. The waveforms used to generate the gingival margins can also be visualized. The CAM data set for the blank can also specify properties of the blank in addition to the shape, such as for example the uneven structure of the blank, in order to generate a visual gingival representation. Such a structure can be formed by a multicolored blank (pink / white) with an uneven color distribution in a wave shape. In the blank, however, an inhomogeneous material distribution with multiple materials can also be present, which is likewise described by the CAM data set for the blank.

Abstract

The invention relates to a method for generating a CAM data set, comprising the following steps: providing (S201) a digital CAD data set for a dental restoration, the CAD data set having first reference data for a first spatial reference geometry; providing (S202) a digital CAM data set, the CAM data set having second reference data for a second spatial reference geometry; and integrating (S203) the CAD dataset into the CAM dataset by aligning the first spatial reference geometry of the CAD dataset on the second spatial reference geometry of the CAM dataset.
