Introduction: There are different manufacturing methods and materials for laboratory models to produce dental substitutes. Plaster models are generally used, and due to advances in computer technology and digitization in dental laboratories, plastic models and virtual computer models are being developed. Purpose: Purpose of the diploma work is to review the various literature to produce models, the manufacturing processes and the time of production of models by reviewing contemporary literature. In the clinical case, we will outline the manufacturing options, common practice mistakes, and the various paths that lead to the finished product. We will compare the plaster model with the three-dimensional printed model. Methods: In the theoretical part of diploma work, the method used is descriptive. We found literature in peer-reviewed scientific journals and professional books, using libraries and professional bases such as Cobiss, PubMed, Medline, Web of Science, and Google Scholar. In the practical part, we made a 3-member ceramic bridge in a dental laboratory on a plaster model and a 3D printed model and compared them. Results: Production of individually designed CAD/CAM ceramic dental work with plaster and 3D printed models. The diploma work consists of a description of the production process, pictorial representation and timing of the individual phases. Prosthetic care was carried out on a 3-tooth bridge. Discussion and conclusion: In a modern dental laboratory, we can receive intra-oral digitally captured data from a patient's mouth, representing an intraoral digital image, using a computer program. We can also accept classic prints. We make plaster models with them. Intraoral image capture has many advantages over a classic impression. In most cases, 3D printed models are required. Creating 3D printed models takes more time than making plaster models. Dimensionally the ceramic superstructure made on 3D printed models fits the patient's mouth.
