Post placement and cementation: Part 1.
Premolars can be considered as a separate entity in the category of root canal treated teeth that will receive a full-coverage restoration. Their unique morphology and their susceptibility to high occlusal load, as well as contemporary preparation guidelines that advocate a wide shoulder finish line design will necessitate the placement of a post in the majority of premolars. Although some of the remaining thin walls will be eliminated during preparation, their removal is not recommended prior to the buildup procedure. Any remaining wall structure can provide additional ferrule and serve as an anti-rotation mechanism.
