Introduction: Most laboratories produce a metal base for partial prosthesis with the traditional casting procedure, but several new technologies for producing a metal base appeared. Besides the tradicional casting process of the metal base, the production of metal structures with SLM technology and stereolithography is also available on the market, which is increasingly used in dental laboratories. Purpose: The purpose of my diploma work is to describe and compare three methods of making a metal base for partial prosthesis and present it with the practical model. Methods: Diploma work has been prepared based on the review and examination of Slovene and foreign professional literature. The metal base for partial prosthesis was manufactured using three different methods of technology: metallic base casting methods, SLA technology and SLM technology. The selected technologies did not have a decisive influence on the final appearance of metal frames. The metal base according to the SLM method was then made to the final product. Practical work is carried out in a dental laboratory and documented with image material. Results: In addition to the established method of casting the metal base, we also presented two more modern methods od making a metal frame for partial prosthesis. Technologies differ from each other according to the choice of hardware and the material used. The final product is appropriate for all. Conclusion: The production of a metal base according to three different manufacturing methods has shown that the technologies vary in the materials and the machinery we used. All metal structures are in the end comparable to each other and there is no difference between them. During the proces of making metal bases, we found that there were differences between the polishing, according to the chosen technology.
