In this paper, a small section of dentistry is described which deals with the design of dental bridges and crowns. Specifically, in this section, the focus is on production of metal bridges with 3D printing technology. The work is divided into six chapters. The first four chapters refer to the theoretical part of dental modeling. In the first, introductory part, describes various methods used throughout history for dental purposes in order to find a solution to the problem. Historical review refers to the beginnings and the first appearance of the dental bridges up to today's modern production methods. Because of the main topic is 3D printing of cobalt-chromium alloys, the first part describes the principle of this printers and other similar methods. Additionally, a review of the materials used for these purposes is given, and the properties of alloy are described more closely. At the end of the fourth chapter, there is a tabular overview of the advantages and disadvantages of this production method. With the fifth chapter starts with an experimental part where the material characterization procedures are described. The analysis was carried out on three different models of dental crowns of three different manufacturers made from the same material, using the same production method, but including different parameters. The microstructure and micro-hardness characterization was performed on these samples. The analysis was carried out before and after ceramic coating. This test was intended to demonstrate whether the high temperatures, which are part of the ceramic coating process, have an impact on the properties of the material. At the end of the paper, there are tabular and diagrammatic outcomes of the test results with accompanying comments.
