The paper presents the possibility of using an innovative hydroxyapatite filament Ca10(PO4)6(OH)2 for printing in 3D printers of bone implants and the possibility of using it during implantation with voice prostheses. The introduction of an additional colloidal silver composite in voice implants will contribute to the reduction of bacterial infections, fungal infections and granulomatous hyperplasia. The creation of a stable external ring of the vocal fistula will remove complications associated with it with enlargement of the fistula and leakiness of voice implants. The ability to print with a hydroxyapatite filament will allow digital pre-surgery modeling of bone implants suited to the needs of surgical procedures.

Agar Diffusion Test

Chitosan beads with colloidal silver nanoparticles inclued in the polymer matrix have been obtained by the introduction of chitosan into an acidified nanosilver sol. Dual interconnection of drops of the resulting solution was then carried out by ionotropic gelation at the first stage and covalent crosslinking of the polymer matrix with adipic acid at the second stage. The surface morphology of the obtained beads was studied by scanning electron microscopy. Data of Fourier transform IR spectroscopy confirmed the formation of covalent bonds between chitosan and adipic acid. The antibacterial activity of obtained beads against S. aureus and E. coli was evaluated using agar diffusion test. It was shown that the сhitosan beads modified with nanostructured silver exhibited an antibacterial effect against the tested strains, and they can be used as a basis for creating biodegradable wound healing dressings with a prolonged antibacterial effect. chitosan, silver nanoparticles, antibacterial activity, wound dressings This work was supported by the "Russian Academic Excellence Project 5-100". The study was carried out with the financial support of the Russian Foundation for Basic Research in the framework of the Scientific Project no. 18-29-18039.
