Introduction: The use of bar attachment systems in modern fixed_removable dental prosthetics plays a key role in enhancing the retention, stability and functionality of dentures. They are particulary prominent in implant-supported overdentures, where they provide even load distribution and grater patient comfort. Advances in materials such as PEEK and PEKK, along with the integration of digital technologies (CAD/CAM, 3D printing), have significantly improved the mechanical propreties, aestheticcs and precision of bar systems fabrication. Bars are available in various designs, allowing for adaptation to anatomical and clinical requirements. Materials such as titanium, zirconia oxide ceramica, composites and metal alloys are selected based on mechanical strenght, biocompatibility and aesthetic criteria. Biomechanicallly bar systems reduce micromovements between implants and enhance the overall stability and longevity of prosthetic restorations. Galvanoforming also plays a significant role by enabling the precise fabrication of metal components, thus improving frictional retention and contributing to the overall durability and stability of the prosthesis. Purpose: Purpuse of this thesis was to present the laboratory procedure for the fabrication of maxillary an mandibular removable partial dentures with cast bases supported by bar attachment systems in fixed-removable dental prosthetics, while the practical part is based on the fabrication of prosthetic constructions. Based on practical work, two hypotheses were tested: digital procedures enable more time-efficient fabrication process, and that precise placement of fabricated bars is essential for the proper function of bar attachment system. Methods: The thesis is based on descriptive research method, involving the analysis of professional and scientific literature on bar systems in fixed-removable dental prosthetics. Sources were obtained through the Digital Library of the University of Ljubljana (DiKUL) and Google Scholar, using English keywords. The review focused mainly on scientific publications from the last decade. Empirical part involved the laboratory fabrication of maxillary and mandibular removable partial dentures with cast bases supported by bar attachments using both conventional and digital procedures, with emphasis on accuracy and functional suitability of the final product. Results: In the practical part, maxillary and mandibular removable partial dentures with cast bases supported by bar attachments were successfully fabricated, demonstrating appropriate fit, stability, and functional and aesthetic acceptability. Digital procedures enabled a more time-efficient and preciste fabrication compared to conventional methods, and the importance of accurate placement of prefabricated bars using a dental surveyor was confirmed. Discussion and conclusion: In this thesis, I presented the fabrication of partial denture with cast metal base, supported by natural teeth, without the use of implants. The work was primarily carried out using conventional analog techniques, with limited digital integration. During the process, I encountered several practical challenges which, despite my initial experience, provided valuable learning opportunities. Errors such as the lack of diagnostic setu pand improper sequencing emhasized the importance of planing, precision and technical consistency. Bar attachment systems play a crucial role in the stability and functionality of prosthetic solutions. Through this project, I gained practical experience that will help improve my future execution of similar cases, while also deepening my understanding of the responsibilities and complexity of the dental technician's profession.
