A Novel Concept for Developing a Precise and Predictable Post and Core Complex Using the Injectable Resin Technique.

Abstract

Post systems have long been used in the roots of teeth to retain dental restorations. The primary objectives of current post and core systems are to replace missing coronal tooth structure, retain the core, and provide sufficient retention and resistance form to the final restoration to restore original form and function. Many varieties of user-friendly post and core systems are available today for different endodontic, restorative, and esthetic requirements. The present article provides a history of post and core usage in dentistry, describes various systems and materials for this purpose, and discusses empirical data regarding fiber-reinforced post systems.
