Evaluation of Antimicrobial Performance of Calcium Dihydroxide (Ca(OH)) Coating on Ti for Potential Metallic Orthopedic Implant Applications.

Orthopedic implant infections are rare but represent a significant problem for patients, surgeons, and the healthcare systems. This is because these infections cause severe and persistent pain and, in some cases, may require revision of the implant, among other things. Thus, there is strong interest in the use of antimicrobial coatings on orthopedic implants.

Lattice Microarchitecture for Bone Tissue Engineering from Calcium Phosphate Compared to Titanium.

Additive manufacturing of bone tissue engineering scaffolds will become a key element for personalized bone tissue engineering in the near future. Several additive manufacturing processes are based on extrusion where the deposition of the filament will result in a three-dimensional lattice structure. Recently, we studied diverse lattice structures for bone tissue engineering realized by laser sintering of titanium.

Evaluation of calcium dihydroxide- and silver-coated implants in the rat tibia.

Background: Silver ions (Ag+) have strong antibacterial effects, and silver-coated materials are in widespread clinical use. However, the application of silver-coated medical devices is not without concerns: its use with direct bone contact is not established, and systemic toxic side effects of released Ag+ have been described. Therefore, alternative bactericidal coatings with a more localized way of acting - e.
