Coltenetenax fibre posts

Although they do not have the rigidity of a metal post, fiber posts are indicated for: cases where a metal post would jeopardize the esthetic result; at-risk patients who have a past history of trauma to the orofacial region and the placement of a metal post would put an endodontically treated tooth at risk of root fracture; teeth with sufficient remaining coronal structure so that a 1.5-mm to 2-mm ferrule can be developed in the crown preparation.

The indications for a post and core restoration are done when tooth with extensive crown loss, crown susceptible to cervical area fracture, grossly discolored tooth, loss of two proximal surfaces, a shortened tooth with insufficient retention form with the favorable periodontal and periapical condition.
