Final answer:
Core buildups, pins, and posts are dental techniques used to strengthen tooth structure and provide stability for crown retention.
Step-by-step explanation:
Core buildups, pins, and posts are dental techniques used to strengthen tooth structure and provide stability for crown retention.
A core buildup is the restoration of a tooth's missing coronal structure, usually done with a dental material like composite resin or amalgam. It provides a foundation for the placement of a crown.
Pins and posts are used in cases where there is insufficient tooth structure to support a crown. Pins are small metal rods that are inserted into the tooth structure to provide additional support. Posts are longer and typically extend into the root canal space to anchor the crown.
