Why is the metal post still so used if the fiber post has so many advantages for the tooth?
Metal posts cost less than fiber posts and can also be placed in only one clinical session.

Reforpost Metal is not screwable
Reforpost Metal must be cemented passively. Screwable posts are harmful to the dental structures and lead to a greater probability for root fractures. 

Reforpost Metal can be used in anterior teeth
But in these cases the post must be masked by an opaque resin (OPAK-ANGELUS).

Material which can be used to cement Reforpost Metal
Any kind of cement (zinc phosphate, glass ionomer or resin cements). Resin cements present the best mechanical properties. Among them, the self cured resin cement is the best indication for posts.
