The relationship of post design to the long-term success of endodontically restored teeth.
Artificial cores replace missing tooth structure and contribute to the retention and stability of the subsequent restoration. The post is the anchoring mechanism for the core, which supports the final restoration. Stability of the post and core is the most important factor concerning the long-term success of the post-and-core restoration. The amount of insertional and functional stresses produced and distributed by a post are also associated with retention. An optimal way of maximizing retention, minimizing insertional stresses, and distributing functional stresses may be through the use of a multi-tiered parallel threaded split-shanked post.
