“…To ensure the highest quality of services are also provided for patients who, without the use of the latest technologies, are condemned to basic prosthetic solutions, such as settling dentures, the normal practice of dentists is in the area of interest of which dental prosthetics is daily in close cooperation with dental engineers that are having access to the latest achievements in engineering in prosthetics and dental implantology. A broad scope of engineering aiding in contemporary dentistry is associated with the use of the achievements of material engineering, manufacturing engineering, and tissue engineering, as part of the current stage of the Industrial 4.0 of the industrial revolution [1,. The industrial revolution began with the invention of the steam machine in the Industry 1.0 stage, followed by electricity and a production line, then automation and computerization, and now cyber-physical systems have been introduced.…”

“…The industrial revolution began with the invention of the steam machine in the Industry 1.0 stage, followed by electricity and a production line, then automation and computerization, and now cyber-physical systems have been introduced. It is inextricably linked to the introduction of the analogous approach of Materials 4.0 [1,20,22,24,37,[78][79][80][81][82][83][84][85][86][87][88][89][90].

The paper is a comprehensive but compact review of the literature on the state of illnesses of the human stomatognathic system, related consequences in the form of dental deficiencies, and the resulting need for prosthetic treatment. Types of prosthetic restorations, including implants, as well as new classes of implantable devices called implant-scaffolds with a porous part integrated with a solid core, as well as biological engineering materials with the use of living cells, have been characterized. A review of works on current trends in the technical development of dental prosthetics aiding, called Dentistry 4.0, analogous to the concept of the highest stage of Industry 4.0 of the industrial revolution, has been presented. Authors’ own augmented holistic model of Industry 4.0 has been developed and presented. The studies on the significance of cone-beam computed tomography (CBCT) in planning prosthetic treatment, as well as in the design and manufacture of prosthetic restorations, have been described. The presented and fully digital approach is a radical turnaround in both clinical procedures and the technologies of implant preparation using computer-aided design and manufacturing methods (CAD/CAM) and additive manufacturing (AM) technologies, including selective laser sintering (SLS). The authors’ research illustrates the practical application of the Dentistry 4.0 approach for several types of prosthetic restorations. The development process of the modern approach is being observed all over the world. The use of the principles of the augmented holistic model of Industry 4.0 in advanced dental engineering indicates a change in the traditional relationship between a dentist and a dental engineer. The overall conclusion demonstrates that it is inevitable and extremely beneficial to implement the idea of Dentistry 4.0 following the assumptions of the authors’ own, holistic Industry 4.0 model.

The purpose of this paper is to compare the impact of selective laser-sintering (SLS) technology and computer numerical control (CNC) machining methods on the structure and properties of solid Co-Cr-W-Mo-Si alloys. Structural tests were carried out using x-ray structural analysis; energy-dispersive x-ray spectroscopy chemical composition analysis; metallographic investigations using stereoscopic, light, and scanning electron microscopes using computerized methods of quantitative metallography; and tests of tensile, bending, and compression strength. Individually designed microsamples were used, and the results were statistically processed. It was shown that if optimal conditions of SLS technology are used, it is possible to obtain a structure with a pore content of 0.1 % smaller than in the case of solid cast materials. This ensures better mechanical properties than cast materials. At the same time, it was pointed out that even minor technological errors associated with SLS technology caused a lowering of all strength properties associated with a significant increase in porosity by up to 10 %. Allowing small changes in technological conditions, including the width of the laser spot, the width of the laser beam, the allowance associated with the overlap of the laser beam, disturbances in the flow of inert gas, and uncontrolled changes in the laser power, can cause a significant reduction in strength. A plug and play approach is unacceptable. If even one layer with a thickness of 25 μm is produced in suboptimal conditions, the manufactured element cannot meet the assumed requirements. The use of SLS additive technology for the production of prosthetic components made of Co-Cr alloys is the best choice among the methods currently used in dentistry. The use of SLS technology together with the digitization of design and manufacturing processes is an important element in implementing the Dentistry 4.0 approach as part of the Industry 4.0 stage of the industrial revolution.

Small and medium-sized manufacturing enterprises have the characteristics of large numbers and small scales. Problems such as backward manufacturing technology, lack of talents, small amount of information resources, and insufficient product research and development capabilities have severely restricted the development of enterprises. The backward manufacturing design model cannot adapt to the development trend of modern manufacturing informatization. This paper proposes and designs a fuzzy inference model and fuzzy inference engine algorithm with threshold. In order to describe the numerical multiple input and multiple output variables in the industrial manufacturing design industry, the relevant experience is used to make numerical reasoning decisions. Applying fuzzy sets and fuzzy theory to the expert system, a fuzzy rule model containing the membership function information and thresholds of the corresponding fuzzy sets is proposed and established, and a fuzzy reasoning system suitable for numerical and uncertain reasoning decisions is constructed. The improved grey relational analysis method is used to decompose and evaluate the exponential mathematical quantitative process of manufacturing enterprises. Based on the fuzzy Decision Analytic Network Process (DANP) method to calculate the relative weight of the influencing factors in the evaluation system, the evaluation index of the enterprise is obtained. Starting from the industrial manufacturing design process, this article constructs a relatively comprehensive and reasonable enterprise exponential mathematical quantitative process decomposition evaluation system. Considering that there are complex interactions between the various influencing factors in the system, the fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) method is selected to process the direct impact matrix of the evaluation system, and the causal relationship between the indicators is obtained. The fuzzy exponential gray correlation method is used to evaluate the quantitative process of industrial manufacturing design, avoiding the shortcomings of traditional methods that only consider ideal values.
