A tooth with a crown root fracture, must have enough coronal tooth structure to establish a ferrule for the crown or abutment and ensure closed margins and to prevent coronal leakage. A previous history of trauma could be an etiology for a crown root fracture. Fractures can be verified by transillumation under crowns or abutments in cracked teeth.
