An intra-coronal post is a dental restoration component used to rebuild a tooth that has undergone significant damage, typically due to decay or trauma and which retains sufficient structure to support a new restoration.

Insertion of the Post: The intra-coronal post, typically made of materials like metal, ceramic, or composite resin, is inserted into space created within the tooth root. The lost structure is replaced either directly with restorative build up materials added around the post or indirectly where a technician will cast it with the post and the hold unit is then inserted together.

Reasons why intra-coronal posts might need to be removed include:

Failure or Damage: Sometimes, the post itself can become damaged or loosen over time due to factors like chewing forces or trauma. If the post fails structurally, this will lead to restoration failure and it may need to be removed and replaced to restore function and allow for the stability of a new restoration.

Infection or Decay: If decay or infection develops around the area where the post is inserted, it may compromise the integrity of the restoration. In such cases, the post may need to be removed to address the underlying issue and prevent further damage to the tooth.

Re-evaluation of Treatment: In some cases, a dentist might determine that the intra-coronal post is no longer appropriate for the tooth. This could be due to changes in the tooth’s condition or advances in dental technology that offer alternative improved treatment options.
