ABSTRACT
A time-sharing technique for a CAD-CAM unit can avoid scheduling difficulties and lengthy appointments. Dentists can also share the cost of expensive equipment and involve staff in learning the steps of this computer-aided design and manufacture.

Endodontically-treated, pulpless teeth tend to become brittle and loose their natural resistance to intraoral functional stress. To retain the core to the root, posts are placed in such teeth. This article presents the rationale for placing the posts, reports past results, and discusses the current materials and implementation procedures. Understanding those principles is the learning objective of this article.

It is common practice to 'reinforce' the endodontically treated tooth with a post-and-core combination (either custom or prefabricated) and ultimately restore it with a crown. Many studies have looked at the post, treatment of the post surface, the cements and other factors. It appears that, regardless of the treatment of the post surface, current post cementing technology enables the practitioner to achieve higher retention than previously possible.
