What is ferrule effect?
A ferrule means "a metal ring or band around a slender shaft that prevents splitting".
The band of extracoronal material (usually metal or metal ceramic) that encompasses this tooth tissue is termed ferrule and is usually provided by the crown that is placed over the post and core.
The ferrule is the ring of metal that goes along the gingival margin of a
crown or a core buildup. It's not a ring of tooth structure. The
tooth structure is removed in order to place a ferrule.
The theory is that a ferrule will help distribute lateral forces and prevent fracture after you do a post and core.
