Abstract
The invention relates to a single- or multi-unit dental restoration, which consists of a support structure and a veneer, which support structure is in particular made from oxide ceramics by means of additive manufacturing, particularly preferably by means of rapid prototyping, wherein the veneer is produced by pressing a ceramic material, such as a glass ceramic or composite material, which is more translucent than the support structure, characterized in that the veneer fills and/or penetrates recesses of the support structure (12) configured as a net or frame structure or as a reinforcement, wherein it is particularly provided that the recesses penetrate through the support structure (12).
Claims22
A single- or multi-unit dental restoration, comprising
- a support structure and a veneer, the support structure is made from oxide ceramics by additive manufacturing,
- wherein the veneer is produced by pressing a ceramic material, the ceramic material is more translucent than the support structure,
- wherein the veneer fills and/or penetrates recesses of the support structure configured as a tree-like structure with branches, the recesses formed between the branches, and
- wherein the recesses extend through the support structure.
A dental restoration which comprises
- a ceramic support which forms a support structure and
- a veneer,
- wherein the ceramic support is made by additive manufacturing with a ceramic material comprising an oxide or glass ceramic material,
- wherein the veneer is produced by pressing a second ceramic material, which is more translucent than the ceramic material of the support structure,
- wherein the ceramic support is configured as a tree-like structure with branches, with recesses formed between the branches, the recesses filled with the veneer.
A method of producing a single- or multi-unit dental restoration comprising
- producing a veneer by CAD design software in such a manner that the CAD software initially constructs a ceramic support which is made from oxide or glass ceramic materials by additive manufacturing,
- wherein the veneer is produced by pressing a second glass ceramic material, which is more translucent than the oxide or glass ceramic materials of the ceramic support,
- wherein the CAD software determines boundary surfaces between the ceramic support and the veneer such that the ceramic support is configured in a tree-like structure with branches, with recesses formed between the branches, said recesses filled by the second glass ceramic material.
