The Effect of Antibacterial-Osteogenic Surface Modification on the Osseointegration of Titanium Implants: A Static and Dynamic Strategy

ACS Biomaterials Science & Engineering, Journal Year: 2024, Volume and Issue: 10(7), P. 4093 - 4113

Published: June 3, 2024

Titanium (Ti) and its alloys are widely used biomaterials in bone repair. Although these possess stable properties good biocompatibility, the high elastic modulus low surface activity of Ti implants have often been associated with infection, inflammation, poor osteogenesis. Therefore, there is an urgent need to modify implants, where changes morphology or coatings loading can confer specific functions help them adapt osseointegration formation phase resist bacterial infection. This further ensure a healthy microenvironment for regeneration as well promotion immunomodulation, angiogenesis, this review, we evaluated various functional after modification, both terms static modifications dynamic response strategies, mainly focusing on synergistic effects antimicrobial activities functionalized osteogenic. Finally, current challenges future perspectives summarized provide innovative effective solutions defect

Preparation and antibacterial activity of Ag-doped TiO2 coating on the porous surface of aluminum

Journal of Materials Research and Technology, Journal Year: 2024, Volume and Issue: 32, P. 1801 - 1808

Published: Aug. 10, 2024

Aluminum (Al) and its alloys have been widely used in daily life, but the absence of antibacterial properties makes them potential vectors for bacterial transmission. In this study, an Ag-doped TiO2 coating was successfully prepared on porous surface etched Al foil using sol-gel method. The results indicated that layer allowed gel to permeate through holes, thereby forming interface carrying these agents with a thickness about 10 μm. Ag dopant promoted transformation titania from rutile anatase during calcination process, being absent when atomic ratio Ti reached 0.10. Meanwhile, doped Ag+ thermally decomposed into metallic Ag0. As result, doping enhanced photocatalytic efficacy coating. Moreover, rate against Escherichia coli Staphylococcus aureus under dark conditions could reach more than 99%, corrosion resistance also slightly improved by it.
