Post Crown and Core build up

107

Teeth that have become severely compromised by decay, large fracture or big failed restorations often require full-coverage crowns to restore them to their original form and function. In cases where root canal therapy is needed. dentist must then evaluate whether there is enough structural integrity remaining to support a definitive crown by a core build-up alone, or use a retained post (pin) to secure the core foundation to the root and distribute bite force to root. The main purpose of a core build- up is to replace enough missing tooth structure to allow the creation of ideal resistance and retention of the crown preparation.
