Post and Core
Overview
Post and Core at Rehan Dental Surgery
A post and core crown is recommended when there isn’t enough natural tooth structure to support a conventional crown. In this procedure, a post is cemented into a prepared root canal to retain a core restoration, which in turn supports the final crown. The post helps hold the crown in place and distributes biting forces along the root, but it does not strengthen the tooth itself and may even increase the risk of root fracture if not properly planned.
Before placing a post and core crown, the dentist evaluates several factors: the presence of sufficient coronal tooth structure (ferrule), adequate canal length to retain the post, the shape and curvature of the root canal system, thickness of the root dentin, and the overall restorability of the tooth. Proper assessment ensures a durable, functional, and long-lasting restoration.
Benefits of Post and Cores.
Placing a post in a root canal improves crown retention, but it comes with risks, including root perforation, increased fracture likelihood, difficulty with future root canal treatments, and significant removal of tooth tissue. The presence of a ferrule can help strengthen the restoration.
Posts are more commonly needed for anterior teeth, as posterior teeth often have larger pulp chambers that provide sufficient retention for a core and crown. If a post is required for a posterior tooth, only one should be used in the largest canal to avoid excessive dentin removal. Alternatively, a Nayyar core may be used for better support without the need for multiple posts.
