“…Metal materials, such as hip replacements, dental implants, and cardiovascular stents, have been widely applied in hard tissue replacements or restorations with promising results due to their superior mechanical properties [ 1 , 2 ]. However, metal materials applied in soft tissue-related fields are relatively limited, partially related to the difficulties in establishing effective integration between metal and soft tissue [ 3 , 4 ].…”

“…Weijian Hua et al [ 23 ], showed the 3D printing method to also be a powerful tool for stent manufacturing. Kaitlyn Chua’s work also illustrates how the field of 3D printing and biomedicine can create more innovative devices and products [ 24 ]. For 3D printing, the manufacturing structure is already very simple.…”

Laser additive manufacturing (LAM) of complex-shaped metallic components offers great potential for fabricating customized endovascular stents. In this study, anti-tetrachiral auxetic stents with negative Poisson ratios (NPR) were designed and fabricated via LAM. Poisson’s ratios of models with different diameters of circular node (DCN) were calculated using finite element analysis (FEA). The experimental method was conducted with the LAM-fabricated anti-tetrachiral stents to validate their NPR effect and the simulation results. The results show that, with the increase in DCN from 0.6 to 1.5 mm, the Poisson ratios of anti-tetrachiral stents varied from −1.03 to −1.12, which is in line with the simulation results. The interrelationship between structural parameters of anti-tetrachiral stents, their mechanical properties and biocompatibility was demonstrated. The anti-tetrachiral stents with a DCN of 0.9 mm showed the highest absolute value of negative Poisson’s ratio, combined with good cytocompatibility. The cytocompatibility tests indicate the envisaged cell viability and adhesion of the vascular endothelial cell on the LAM-fabricated anti-tetrachiral auxetic stents. The manufactured stents exhibit great superiority in the application of endovascular stent implantation due to their high flexibility for easy maneuverability during deployment and enough strength for arterial support.

“…They are determined using the analysis of occlusion, the state of muscle tension and work, and the dynamics of the articulation states of the mandible. Its functionality and aesthetics are determined by clinical procedures, manufacturing technology, the biomaterial used and its strength parameters [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ].…”

“…There is a lot of information available in the literature on individual technologies, concerning material compositions [ 16 , 17 ], manufacturing procedures [ 3 , 7 , 11 , 12 , 18 ], and microstructural and micromechanical analyses [ 1 , 9 , 10 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. However, they often concern only one group of alloys.…”

The production of fixed prosthetic restorations requires strength identification in terms of cognition and the targeted clinical applications. The aim of the study is to evaluate the static strength in axial tensile and compression tests of titanium and cobalt alloys for the supporting foundations of crowns and bridges produced using Computer Aided Design and Manufacturing (CAD/CAM) technologies: Direct Metal Laser Sintering (DMLS) and milling. The test materials are samples of Ti6Al4V and CoCrMo alloys obtained using digital technologies and, for comparison purposes, CoCrMo samples from traditional casting. For the studied biomedical alloys, R0.05, Rp0.2, Rm and Ru were determined in the tensile tests, and in the compression tests R0.01, Rp0.2 and the stress σ at the adopted deformation threshold. Tensile and compression tests of titanium and cobalt alloys indicate differences in strength parameters resulting from the technology applied. The manufacturing of the structures by DMLS provides the highest stress values that condition elastic deformations for cobalt biomaterials: R0.05 = 1180 MPa, R0.01 = 1124 MPa and for titanium biomaterials: R0.05 = 984 MPa, R0.01 = 958 MPa. The high resistance to deformation of CoCrMo and Ti6Al4V from DMLS may be beneficial for fixed prosthetic structures subjected to biomechanical stresses in the stomatognathic system and the impact of these structures on the dento-alveolar complex.
