Hemisection involvesseparation and removal of a part of the crown and root of a tooth affected by inflammation with irreversible pathological lesions.
During the hemisection procedure the dentist removes the damaged crown of the multi-root tooth together with the corresponding crown. Hemisection is carried out on multi-rooted teeth (usually molars).
With this procedure the dentist can keep a fragment of the tooth that can later serve as an abutment tooth in subsequent prosthetic reconstruction (see -> crowns).Hemisection also allows the dentist to prevent potential inflammatory lesion around the tip of one of the roots.
Hemisection is a procedure carried out when conservative treatment is no longer possible. Indications for hemisection include:
- apical lesions next to the roots
- failure of endodontic treatment
- vertical fracture of tooth and/or root
