The endodontically treated tooth is a unique subset of teeth requiring restoration because of several factors such as dehydrated dentin, decreased structural integrity and impaired neurosensory feedback mechanism when compared to a vital tooth. However, the treatment goal must be based upon a multitude of factors specific to each patient, so that the strategic architectural aspects that have the greatest impact on the ultimate strength of the pulpless tooth can be restored/ reinforced. The solution to this problem has challenged the inventiveness and ingenuity of dentists for centuries. A post...
The endodontically treated tooth is a unique subset of teeth requiring restoration because of several factors such as dehydrated dentin, decreased structural integrity and impaired neurosensory feedback mechanism when compared to a vital tooth. However, the treatment goal must be based upon a multitude of factors specific to each patient, so that the strategic architectural aspects that have the greatest impact on the ultimate strength of the pulpless tooth can be restored/ reinforced. The solution to this problem has challenged the inventiveness and ingenuity of dentists for centuries. A post and core is a restoration consisting of a post that fills a prepared root canal and a core inserted into the pulp chamber that establishes the proper coronal tooth preparation. The post and core is made with a rigid material which, when cemented into the root canal and pulp chamber, provides a solid foundation restoration that is well retained in the tooth. So, the primary function of a post is to aid in retaining a core to restore lost tooth structure for retention of a restoration and not to provide strength or resistance to fracture.
