Properties and applications of Bioplast, an absorbable surgical implant material from fibrin

Bioplast is the only commercially available absorbable implant material. Compression moulded from fibrin, it is a yellowish, translucent and flexible material which is thermally stable below 170 degrees C. Its mechanical strength depends on glycerol content. Crosslinking with formaldehyde reduces swelling and digestibility. Bioplant is non-antigenic and capable of being absorbed by polymorphonuclear digestive action. The non-toxic metabolites are eliminated via the kidneys while the site is invaded by host tissue. Clinical applications are mentioned.
