“…The excellent performances and unique viscoelastic properties of the APEG systems enable the facile processing and customized design of functional materials by direct 3D printing, [ 32–34 ] as shown in Figure S13, Supporting Information. Under shearing, the APEGs can continuously be extruded out of the nozzle with the viscous modulus G ″ larger than the elastic modulus G ′.…”

Properties of emulsions highly depend on the interdroplet interactions and, thus, engineering interdroplet interactions at molecular scale are essential to achieve desired emulsion systems. Here, attractive Pickering emulsion gels (APEGs) are designed and prepared by bridging neighboring particle‐stabilized droplets via telechelic polymers. In the APEGs, each telechelic molecule with two amino end groups can simultaneously bind to two carboxyl functionalized nanoparticles in two neighboring droplets, forming a bridged network. The APEG systems show typical shear‐thinning behaviors and their viscoelastic properties are tunable by temperature, pH, and molecular weight of the telechelic polymers, making them ideal for direct 3D printing. The APEGs can be photopolymerized to prepare APEG‐templated porous materials and their microstructures can be tailored to optimize their performances, making the APEG systems promising for a wide range of applications.

“…In order to address this issue, 4D-printed implants can react to different stimuli and change their structure with the passage of time [ 15 , 18 ]. Despite the plethora of advantages, such as the ability to manufacture intelligent materials and the construction of complex anatomical structures [ 18 , 19 ], one of its major potential drawbacks is the deformation control accuracy, due to the fact that the shape-morphing system relies on a biaxial stretch device [ 20 ].…”

Over the past three decades, additive manufacturing has changed from an innovative technology to an increasingly accessible tool in all aspects of different medical practices, including orthopedics. Although 3D-printing technology offers a relatively inexpensive, rapid and less risky route of manufacturing, it is still quite limited for the fabrication of more complex objects. Over the last few years, stable 3D-printed objects have been converted to smart objects or implants using novel 4D-printing systems. Four-dimensional printing is an advanced process that creates the final object by adding smart materials. Human bones are curved along their axes, a morphological characteristic that augments the mechanical strain caused by external forces. Instead of the three axes used in 4D printing, 5D-printing technology uses five axes, creating curved and more complex objects. Nowadays, 6D-printing technology marries the concepts of 4D- and 5D-printing technology to produce objects that change shape over time in response to external stimuli. In future research, it is obvious that printing technology will include a combination of multi-dimensional printing technology and smart materials. Multi-dimensional additive manufacturing technology will drive the printing dimension to higher levels of structural freedom and printing efficacy, offering promising properties for various orthopedic applications.

“…Powder metallurgy, 3D printing, and additive manufacturing are just some of the potential manufacturing techniques. Porous implants and implant-scaffolds, both metal, and ceramic, can be designed and manufactured using additive methods, the so-called 3D printing [139,[282][283][284][285][286][287][288][289][290][291]. However, powder engineering is still offered wide possibilities, traditionally called powder metallurgy [137,138,152,292,293].…”

“…Figure 29 shows an example of manufacturing a full-arch prosthetic bridge based on tooth abutments through milling in a CNC center from conventionally cast discs. Porous materials made from powders by additive methods are very useful in some applications [137,138,[282][283][284][285][286][287][288]292,293]. Figure 30 shows the results of studies on selectively laser sintered porous titanium [144], including the structure observed in the highresolution transmission electron microscope HRTEM.…”

This paper is divided into seven main parts. Its purpose is to review the literature to demonstrate the importance of developing bioengineering and global production of biomaterials to care for the level of healthcare in the world. First, the general description of health as a universal human value and assumptions of a long and healthy life policy is presented. The ethical aspects of the mission of medical doctors and dentists were emphasized. The coronavirus, COVID-19, pandemic has had a significant impact on health issues, determining the world’s health situation. The scope of the diseases is given, and specific methods of their prevention are discussed. The next part focuses on bioengineering issues, mainly medical engineering and dental engineering, and the need for doctors to use technical solutions supporting medicine and dentistry, taking into account the current stage Industry 4.0 of the industrial revolution. The concept of Dentistry 4.0 was generally presented, and a general Bioengineering 4.0 approach was suggested. The basics of production management and the quality loop of the product life cycle were analyzed. The general classification of medical devices and biomedical materials necessary for their production was presented. The paper contains an analysis of the synthesis and characterization of biomedical materials supporting medicine and dentistry, emphasizing additive manufacturing methods. Numerous examples of clinical applications supported considerations regarding biomedical materials. The economic conditions for implementing various biomedical materials groups were supported by forecasts for developing global markets for biomaterials, regenerative medicine, and tissue engineering. In the seventh part, recapitulation and final remarks against the background of historical retrospection, it was emphasized that the technological processes of production and processing of biomedical materials and the systematic increase in their global production are a determinant of the implementation of a long and healthy policy.
