Introduction: The aim of any prosthetic treatment is to ensure optimal functionality and aesthetics. In modern dentistry, aesthetics are becoming increasingly important, as is the minimally invasive approach to procedures. Composite is a resin-based, tooth-colored material used for various purposes in dentistry. It is a versatile material that can be shaped and adapted to the natural color and form of the tooth, thus providing a more aesthetic result. Composites are composed of two or more different materials at the macroscopic level. They consist of a matrix, a reinforcing phase, and an additive that bonds these two phases. Ambarino is a new and advanced material in the field of dental prosthetics, offering remarkable properties such as higher elasticity, durability, reduced brittleness, and an optimal ratio of polymers to ceramics. The modulus of elasticity is crucial, as it determines the material’s ability to absorb the forces of mastication. This allows the restoration to bend and adapt under pressure, thereby reducing the risk of fractures and chipping in all types of restorations. Aim: The purpose of this thesis is to review existing professional literature on the fabrication of a metal framework bridge with a composite veneered surface and a full-composite bridge using milling techniques. Additionally, the study aims to compare and describe the manufacturing processes of these types of dental bridges. The goal is to present the key stages of fabrication, advantages and disadvantages of each type of bridge, and their practical application in dental prosthetics, with an emphasis on the technologies and methods used. Methods: In the theoretical part of the thesis, a descriptive method was applied, including the review and analysis of professional literature in the field of dental prosthetics, sourced from online databases (Google Scholar), textbooks, and lecture notes. The main sources of information were scientific articles published in journals and specialized books. The analysis focused on materials and fabrication procedures. In the practical part, two bridges were fabricated in the laboratory. For both cases, the design was modeled using Exocad software. The first bridge was milled from the hybrid material Ambarino, while the framework of the second bridge was printed using SLM technology and subsequently layered with composite material. Results: Two bridges were successfully fabricated using CAD/CAM technology. The framework of the first bridge was produced with SLM technology and veneered with composite in layers. The second bridge was milled from the hybrid material Ambarino and finished through subsequent processing. Discussion and Conclusion: The fabrication of the full-composite bridge was found to be faster compared to the bridge with a metal framework. However, the metal framework with composite veneering provides greater hardness. Moreover, the use of CAD systems or modeling in Exocad significantly shortens the production time of the metal framework, reducing both modeling and fabrication time by at least half.
