Summary: In this study, a thermochemical treatment was used to produce silver-doped calcium titanate coatings on titanium surfaces, enhancing bioactivity and providing antibacterial properties. The release of Ag ions from the coatings showed strong antibacterial effects, preventing bacterial adhesion and proliferation. Additionally, nanostructured topography of the coating reduced bacterial adhesion and proliferation even without Ag, maintaining bioactivity of the implants.

Summary: Titanium alloy Ti6Al4V is commonly used as a bone implant material with a porous structure to match human bone. However, it lacks antibacterial properties and the porous structure increases the risk of infection. This study used 3D printing to prepare porous samples with different porosities and improved their surface properties through anodic oxidation.

Summary: Titanium and Titanium alloys are widely used in oral and maxillofacial surgery as biomedical implants. However, in specific clinical populations, the failure rate of these implants is higher. Studies show that the presence of Reactive Oxygen Species (ROS) increases in the bone tissue surrounding the implants, leading to oxidative stress in the host. Developing antibacterial technologies, incorporating active elements, and creating ROS-responsive implant materials are important areas of research.

Summary: Poor sealing of the titanium implant-soft tissue interface leads to bacterial invasion and inflammation, resulting in implant failure. To improve this, lactoferrin-derived amyloid is coated on the titanium surface to enhance cell integrin expression and provide antibacterial activity. The coated implants promote cell proliferation and adhesion, have a positive charge, and exhibit strong antibacterial activities.

Summary: In this study, a porous 3D-printed magnesium alloy implant with suitable mechanical properties was fabricated and shown to have good cytocompatibility, in vitro osteoinductivity, and antibacterial properties. The implant successfully prevented infection in a rabbit model and demonstrated good in vivo biocompatibility. Additionally, enhanced immunoregulatory effects were observed at the bone-implant interface during the early implantation stage, potentially mediated by the release of high concentrations of magnesium ions.

Summary: In this study, a metal-organic framework (MOF) based drug delivery platform was used to modify titanium implants, providing them with antibacterial activity, biocompatibility, and osteogenesis-promoting properties. The modified implants released Zn2+ and MV, which caused oxidative damage to E. coli and S. aureus, inhibiting bacterial proliferation. Furthermore, the MV@ZIF-8 coating promoted osteogenic differentiation of human bone mesenchymal stem cells by activating the canonical Wnt/b-catenin signaling pathway. This research demonstrates the potential application of MOF-based drug delivery platforms in bone tissue engineering.

Summary: In this study, composite filaments modified with bioglass and Zn-doped bioglass were developed for the production of osteochondral implants. The manufactured filaments exhibited bioactivity, strength, and flexibility. These filaments were then used to produce scaffolds, and the effect of bioglass addition on the mechanical and biological properties of the samples was investigated. The presence of a spatial microstructure within the scaffolds reduced their mechanical properties. In vitro mineralization experiments showed apatite formation on scaffolds modified with bioglass, while apatite formation was delayed on scaffolds modified with Zn-doped bioglass. Innovative 3D-printing filaments containing bioglasses were successfully applied to print bioactive scaffolds suitable for cell attachment and proliferation.

Summary: The high-temperature polymorph of tricalcium phosphate, α-TCP, can hydrolyze to calcium-deficient hydroxyapatite under humidity conditions, which is essential for the development of synthetic bone grafts. The study found that high relative humidity had no immediate impact on α-TCP powder reactivity, but prolonged incubation led to hydrolysis. This reactivity was related to defects and an amorphous phase induced during powder milling. Dynamic moisture studies showed irreversible water sorption and confirmed that water molecules reacted with the powder after a short incubation time.

Summary: The formation of a biological seal around titanium implants is crucial for their success. Fibroblasts play a key role in guiding this process, but in some cases, titanium fails to attract and activate enough fibroblasts. Functionalizing titanium with a modified recombinant heparin binding II (HBII) domain of fibronectin, which includes an Arg-Gly-Asp (RGD) sequence, can enhance fibroblast adhesion and activation. This approach shows promise in promoting the formation of a biological seal.

Summary: The success of titanium implantation may be compromised by Staphylococcus aureus colonization and infection. To address this issue, different strategies have been explored to enhance the antibacterial properties of titanium. In this study, silver nanoparticles and a multifunctional antimicrobial peptide were used to coat titanium surfaces. The density of nanoparticles on titanium was optimized and a two-step functionalization method was used to sequentially coat the surfaces with both agents. The antibacterial effectiveness of the coatings, individually and in combination, was evaluated, and all the tested coatings showed reduced bacteria after 4 hours of incubation. However, after 24 hours of incubation, the individual antimicrobial peptide coating demonstrated greater efficacy against Staphylococcus aureus compared to the silver nanoparticles or their combination. The tested coatings were also found to be non-toxic to eukaryotic cells.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
