PREFABRICATED DENTAL CROWNS.

摘要

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. The dental crowns are preferably preformed or prefabricated with an undercut; tooth colored; for primary or permanent; anterior or posterior teeth; and may include internal metal or other strengthener(s). The undercut has an inwardly arcuate and angled taper toward the gingival end.
