For many years, the dental industry has been researching and improving materials for the production of prosthodontic restorations in order to improve aesthetics, avoid the use of metals and achieve biocompatibility and durability. Until recently, the gold standard in prosthetics was porcelain fused to metal, but due to potential allergic reactions to some components of dental alloys, the trend is to increase the use of full ceramic systems that are biologically inert. The increasing tendency for restorations that would be as similar as possible to natural teeth has led to the development of materials that, with the correct indication and technology of production, produce exactly such results. Today's aspirations of doctors of dental medicine are to achieve, in addition to aesthetics, a high functional value of the restoration with minimal loss of tooth tissue. Given that good mechanical properties are present in the materials for the production of full ceramic crowns, this form of therapy has entered everyday practice. Full ceramic crowns due to their high aesthetic properties, such as translucency and transparency, are a method of choice in solving demanding cases in order to achieve the best possible fit of the prosthodontic restoration into the dental arch. The most commonly used material for the production of metal­free restorations is zirconium oxide ceramic due to the wide range of indications it covers. Zirconium oxide ceramics are characterized by exceptional mechanical, but also due to the technological progress of the material, the advance in the aesthetic properties which have enabled their use in all segments of the dental arch. In this thesis, I will present the case and compare the technologies for producing monolithic and layered crowns from zirconium oxide ceramics.
