“The lack of consensus on the use of intraradicular posts is
further complicated by the fact that the real purpose of post placement is not to increase the resistance of the root but rather to provide mechanical retention for the core. In recent decades, mechanical retention has been progressively substituted by adhesion, and this trend logically undermined the use of posts when using IDS and adhesive crowns”
New evidence is even suggesting that posts may not be necessary in severely damaged anterior teeth without a ferrule because they seriously increase the risk of catastrophic (nonrepairable) fractures. When appropriate adhesive reinforced buildups (no post) or even endocrowns (no post, no core; ) are used instead, the resistance to fracture is increased, and the risk of catastrophic failure is decreased. The type of buildup material can also influence the outcome, and new trends include regular restorative nanohybrids and bulk-fill materials such as short-fiber-reinforced composite resins”
