WOJCIECH MUSIALIK, MARCIN NABIALEK, SLAWOMIR LETKIEWICZ, ANDREI VICTOR SANDU, KATARZYNA BLOCH APPLICATION OF INNOVATIVE HYDROXYAPATITE MATERIALS IN 3D PRINTING FOR BIOCOMPATIBLE VOICE IMPLANTS 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.
