They are made layer by layer and are composed of tooth-like plastic composites. The "printing" of single crowns is already possible, as is the preparation of complex rows of teeth, so-called bridges. But there are also other areas of medicine where printing is already in full swing. However, printing entire organs from cultured cells at the click of a mouse is still wishful thinking. When it comes to the manufacture of precisely fitted hearing aids or artificial limbs, for example, patients already benefit from the advantages, as they are individually designed and can also be produced faster in remote locations than with conventional methods - as long as a suitable 3D printer is available there. In addition, a very precise sensory or photographic measurement is a prerequisite, although the long-term storage and transmission of the captured, sensitive data is still largely unregulated. Another drawback: Some of the layering materials are toxic.
