PDF: Nonmetallic post-endodontic restorations: a systematic review

Posts are generally indicated for restoring endodontically treated teeth that are highly suscepttble to fracture because of their insufficient coronal tooth structure.

Nonmetallic-restorations


Prefabricated posts were traditionally made of metal and might be visible through the structure of endodontically treated teeth, particularly in anterior region. 

Also, they might have different degrees of stiffness. Nonmetallic posts are made either from a resin matrix reinforced with carbon, glass or quartz fibers or from ceramic materials.

With the exception of carbon posts, these posts showed more favorable esthetics in anterior teeth when restored with all-ceramic crowns due to their light-transmitting capacity in addition to their modulus of elasticity values that are similar to that of dentine and this can reduce the risk of tooth fractures and in turn can increase their survival rates when compared to teeth res tored with metallic posts.

Als o, these posts are able to form a monoblock structure created by dentin, resin cement and post.

The systematic reviewing process enables the aggregation of res ults from different studies comparing different types of posts and aims to provide the current best available evidence upon which clinical decisions regarding the selection of endodontic posts can be based.
