Strong Hardness Pfm Dental Full Ceramic Dental Post and Core

A post and core (colloquially known as a "post" or "dental post") is a type of  dental restoration used either to stabilize a weakened tooth or provide an anchor for a crown. Utilized when inadequate tooth structure remains to support a traditional restoration, it consists of the insertion of a small rod (known as a "post") into the root space of an affected tooth, leaving several millimeters protruding. The protrusion is then used to support a large filling, or anchor a crown.

Posts do not strengthen teeth

In past decades there was a misconception that metallic dental posts played a role in reinforcing or strengthening the teeth in which they were placed.

Dental research has since shown that posts offer no reinforcement benefit and, in fact, can actually weaken teeth and place them at risk for fracture.

This does not suggest that post placement is a wrong therapeutic approach. However, a dental post should be utilized only when a large part of the crown structure is missing and no other affordable solutions are available.

The main drawback is that, when all of the independent failure rates of the many procedures needed are considered together (endodontic treatment, post and core fabrication and prosthetic crown), the patient is sometimes advised to have the tooth extracted and a dental implant placed.

It must be said though that in the past decades dental implantology was not at its peak. Post and cores were considered as an alternative to tooth extraction and the subsequent necessity to construct a dental Bridge (which requires the preparation of the adjacent teeth).

Secondly, dental implants entail a higher cost, which some patients cannot afford. For these reasons, post and cores are still utilized all over the world.
