When an incisor is broken vertically, the broken end usually reaches the subgingival area, and depending on the depth of the broken end, the options of filling treatment, root canal treatment, or extraction are recommended.
The main types of incisor trauma are crown fracture, root fracture and crown-root fracture. Vertical fracture of incisors, which usually occurs in the case of crown-root fracture, requires the choice of treatment according to the depth of the broken end.
For the fracture end is deeper under the gingiva, usually the pulp has been exposed and it is difficult to establish a normal epithelial bond between the gingiva and the tooth, so it is recommended to be extracted; for the fracture end is under the gingiva, but it can be retained through the crown lengthening surgery, it is recommended to be restored by root canal treatment followed by crown implantation; for the fracture end is on the gingiva, and it is not exposed to the pulp, it can be filled in directly, and for those exposed to the pulp, it is necessary to restore the fractured incisors after the root canal treatment.
The treatment plan for incisors broken vertically is also affected by the looseness of the tooth and other factors, it is recommended to go to a regular hospital stomatology department for consultation.
