Introduction: Implant rehabilitation is an established method of replacing missing teeth. Zirconium oxide ceramics is a material that can be used to make implants, abutments and prosthetic construction. Abutments and prosthetic structures are manufactured using modern computerised procedures. Designed constructions are milled from ceramic blocks in the green phase, then sintered and surface glazed. Aim: The thesis describes and presents one-piece and two-piece ceramic implants, a comparison between titanium and ceramic implants, ceramic abutments, and prosthetic constructions on ceramic implants. The laboratory procedures to produce a prosthetic construction on one-piece ceramic implants will be described and will be supported by our own pictorial material. Methods: The thesis uses professional literature, professional articles, and articles in scientific journals in the field of laboratory dental prosthetics and dental medicine. The reviewed literature is located in professional online databases: ScienceDirect, PubMed, MedLine, ResearchGate, Wiley Online Library, Quintessence Publish. The construction of zirconium oxide ceramics on ceramic implants is produced in the dental laboratory with the cooperation of a mentor and a dental technician for clinical use on the patient. Results: For a more accurate fabrication of the final prosthetic structure, a temporary structure was first made of polymethyl methacrylate (PoliDent, Volčja Draga, Slovenia), and then a final prosthetic structure of zirconium oxide ceramic DDcubeX2ML (DentalDirekt, Spenge, Germany). Both constructions were made in the computer program 3Shape Dental Studio (3Shape, Copenhagen, Denmark) and milled in the CAM unit digiMill5VHF S1 (Yeti Dental, Engen, Germany). The final milled zirconium oxide ceramic prosthetic construction was sintered in a Mihm-Vogt HT-S/SPEED furnace (Mihm-Vogt, Blankenloch, Germany); after sintering, the structure is individualized with the MiYO Liquid Ceramic system (Jensen, Metzingen, Germany). Discussion and Conclusion: With the development of new ceramic materials and new dental technologies, indications for the use of dental implants in dental medicine are expanding. Today, new technologies, to produce prosthetic care in the dental office and dental laboratory, enable more and more successful solutions for replacing missing teeth. They provide patients with metal-free aesthetic and functional care, which today can be performed with fully digitally guided clinical planning and computer-guided laboratory fabrication.
