BAS-0, BAS-R, BAS-HA

1. September 1993

There are three kinds of bioactive materials with different characteristics and application possibilities:

BAS-0 – Apatite-wollastonite containing bioactive glass ceramic
BAS-R – Resorbable, tricalcium-phosphate-based ceramics
BAS-HA – Hydroxyapatite-based ceramics

Since these fully synthetic materials did not contain any organic elements, there was zero risk of immune reactions or transmission of pathogens.

These bioactive materials were then used for the fabrication of individual implants for facial surgery, such as orbital implants, ear or nose bone prostheses or fusion prostheses of intervertebral discs.
