A tooth split in half can be restored. When a tooth splits under external forces and reaches above the neck of the tooth the movable portion of the tooth can be extracted, the remaining roots are root canalized, a post is fabricated for retention, and a porcelain or all-ceramic restoration is completed. If the cleavage of the molar reaches the bottom of the pulp chamber and separation of the proximal and distal mesial roots occurs, the thin proximal mesial buccal root is usually extracted and the thick distal mesial buccal root is retained. Root canal treatment of the distal mesiobuccal root is followed by fabrication of a metal or all-ceramic post core to complete a continuous crown restoration with the adjacent tooth. If the tooth is longitudinally fractured and cannot be retained, an immediate implant is required at the same time as extraction, and the crown restoration is completed after bone healing.
