PREFACE
The rapid development of digital technologies in recent decades has signi-ficantly influenced contemporary dentistry and dental prosthetics. The intro-duction of CAD/CAM systems, computer-controlled machining centres, and advanced dental biomaterials has enabled the production of highly accurate, aesthetically acceptable, and biologically compatible prosthetic restorations. As a result, digital dentistry has become one of the most dynamically evolving areas at the intersection of biomedical engineering, materials science, manufacturing technologies, and computer-aided production. The continuous development of dental biomaterials has considerably expanded the technological possibilities available for the fabrication of modern dental restorations. Contemporary CAD/CAM systems are capable of processing a wide range of materials, including metallic, ceramic, polymeric, and composite biomaterials, each possessing specific mechanical, physical, biological, and technological characteristics. These differences significantly affect the manufacturing process, machinability, surface quality, and long-term performance of dental prosthetic constructions. The increasing requirements for manufacturing accuracy, surface quality, and process reliability have highlighted the importance of understanding the technological aspects of machining dental biomaterials. Material properties, cutting conditions, tool geometry, machining strategies, and production system stability all play a crucial role in determining the quality of the final product. Particular attention must also be paid to surface integrity, which represents a complex set of geometrical mechanical, and microstructural characteristics of the machined surface and directly influences the functional and biological behaviour of dental restorations. This monograph provides a comprehensive overview of dental biomaterials, their machinability, and the technological aspects of CAD/CAM machining in modern digital dentistry. Attention is devoted to the classification and characteristics of dental biomaterials, factors affecting machinability, machining systems and cutting tools used in dental manufacturing, as well as methods for evaluating surface quality and surface integrity. Emphasis is placed on the relationships between material properties, machining conditions, and the resulting quality of dental prosthetic constructions. The publication is intended for researchers, engineers, students, and professionals working in the fields of manufacturing techno-logies, biomaterials engineering, dental production, and digital dentistry. It aims to contribute to a better understanding of the technological challenges associated with machining dental biomaterials and to highlight the importance of process optimization in achieving high-quality and reliable dental restora-tions.
