Summary: Developing antimicrobial surfaces, including antimicrobial peptide coatings, is a promising approach to overcome dental implant-associated infection. This study presents a fast and efficient chemoselective conjugation technique to coat titanium implant surfaces with antimicrobial peptides. The evaluated surfaces showed antibacterial potency against primary colonizers and pathogens of dental surfaces, as well as demonstrated long-term viability of human dental pulp stem cells.

Summary: This study utilized anodization as a novel approach to immobilize lithium ions on a titanium surface and evaluated the changes in surface characteristics. The results showed that the surface charge characteristics were enhanced on the 3V-anodized surface, leading to increased adsorption of extracellular matrix proteins and improved attachment of osteoblast cells. This study suggests that anodization could be an effective method to promote osseointegration by modifying the surface charge characteristics and allowing for enhanced biological adhesion.

Summary: The study involved preparing a regular nanotube array on titanium surface by anodization, followed by immobilizing a complex of chitosan and zinc ions (CS/Zn) to enhance biocompatibility. The CS/Zn coating not only promoted adhesion and proliferation of osteoblasts, but also up-regulated expression of ALP and OCN. Overall, this method can improve osteogenesis and osteointegration of titanium surface.

Summary: This research focuses on developing a protocol to attach nisin, an antimicrobial peptide, to a nanotextured titanium alloy surface. The coated surface shows high surface energy, suitable for tissue integration, and releases nisin over a period longer than 1 day. The antibacterial properties were confirmed by reduced metabolic activity and viable adhered colonies of Staphylococcus aureus. This study demonstrates the potential of using chemically treated titanium surfaces coupled with nisin for bioactive and antibacterial tissue integration.

Summary: This study investigated the effect of magnesium and strontium surface modification on osseointegration of titanium implants with a hierarchically structured coating. The results showed that both magnesium and strontium-doped hierarchical coatings could promote osseointegration, with magnesium having a stronger effect. In vitro experiments demonstrated that magnesium-doped coatings enhanced cell adhesion, while strontium-doped surfaces promoted osteogenic differentiation of cells.
