Carbon Based Materials
These include Pyrolytic carbon, polycrystalline (Vitreous Carbon), and carbon/silicon interstitial combination.
Vitreous Carbon -Solid or porous vitreous carbon has also been used as an implant material. Being pure carbon, this material is highly resistant to oral and tissue fluids and unlike polymers, contains no stabilizers, plasticizers, etc. It has relatively low impact strength. The shape of the vitreous carbon structure is related to the shape of the polymer from which it arose, thus making it possible to produce a variety of shapes. The manufacturing of vitreous carbon structures requires specialized equipment.
