Restoring the crown of a tooth after root canal therapy is crucial to regain its functionality. In most cases, root canal-treated teeth have significant material loss, necessitating additional support for the crown restoration. To enhance retention, post applications extend into the root canals for added support. In the past, cast posts or metal pins were commonly used for this purpose. However, in recent years, fiber posts have become the preferred choice due to the numerous advantages they offer.
Unlike traditional cast post systems, fiber posts do not require additional steps like taking impressions, which shortens the treatment time.
The white appearance of fiber posts eliminates the issue of metal reflections on the tooth surface, providing an aesthetic advantage.
Compared to metal pin systems, fiber posts do not create stress on the tooth structure since they are not screwed into the tooth. This reduces the risk of cracks forming on the root surface.
With proper oral hygiene and regular dental check-ups, fiber posts offer protection against chewing forces, enabling long-term use.
After a root canal treatment, the remaining tooth structure is evaluated. If there is minimal material loss in the treated tooth, a standard filling may suffice to complete the treatment. However, if there is significant loss of tooth structure, options like inlay, onlay (porcelain filling), or other types of crown restorations may be preferred. In cases where the tooth walls are severely diminished, fiber post and crown restoration should be applied to ensure durability and functionality.
