In situations where all-ceramic
restorations are used for restoring anterior teeth, metal posts
may result in unfavorable esthetic results, such as a grey
discoloration of translucent all-ceramic crowns and the
surrounding gingival margin [8]. Additionally, corrosive
reactions with prefabricated posts may cause complications
involving the surrounding tissues and oral environment,
including a metallic taste, oral burning, sensitization, oral
pain, and other reactions [9]. These concerns have led to the
development of white or translucent posts made of zirconia
and other ceramic materials.
