Endodontically treated teeth have significantly differentphysical properties compared to vital teeth. To ensure functional longevity,endodontically treated teeth must have at least 5 mm of tooth structure coronalto the crestal bone, 2 mm of coronal tooth structure incisal to the preparationfinish line are necessary to ensure functional integrity.
