Fabrication of a root post is preceded by making a special impression of the tooth, particularly one that is drilled for a root canal procedure.
If a tooth has been destroyed by severe caries (more about this in the video caries) and there is hardly anything left of the crown, fixing a conventional prosthesis is no longer possible because the crown will not hold because of insufficient retention.
The solution to this problem is the placement of a post in the filled root canal. After the root canals are filled (more about this in the Root Treatment video ), the fillings in one or more canals are excavated (removed) up to a certain length. Depending on the type used, the post is either cemented immediately into the canal (known as a prefabricated post) or an impression of the tooth is taken, using which the dental technician will create a plaster model (negative replica of teeth) and fabricate the post (custom-made post).
This post will be inserted a week later. With the help of the black pins, the position and shape of the excavation will be transferred, thus aiding in post fabrication. In this way, the technician can produce individual metal posts. A week later, the posts will be cemented in place and the appropriate corresponding elements will be inserted in the prosthesis; this largely helps in maintaning stability and retention of the prosthesis.
