Abstract:
Advanced material is preferably used for the manufacturing of dental crowns which may be used to restore decayed or to protect other compromised tooth structure.

In either of the foregoing, or independently, the advanced material may be formed or applied by flame spray, liquid dispersion, powder coating, compression molding, vacuum forming, injection molding, pressure forming, thermoforming, or additive manufacturing. The later in particular pertains to additive manufacturing of laser sintered PEEK (or three- dimensional printing of same).
