Coronectomy
Coronectomy
Coronectomy (pronounced: /kɔːrəˈnɛktəmi/), also known as intentional partial odontectomy, is a dental procedure where the crown of a tooth is removed, but the roots are left in place. This procedure is typically performed on wisdom teeth, or third molars, that are difficult to extract and pose a risk to the inferior alveolar nerve.
Etymology
The term "coronectomy" is derived from the Latin corona meaning "crown", and the Greek -ectomy meaning "excision".
Procedure
During a coronectomy, the dentist or oral surgeon will make an incision in the gum to expose the tooth. The crown of the tooth is then removed, leaving the roots in place. The gum is then stitched back together. The procedure is typically performed under local anesthesia.
Benefits and Risks
The main benefit of a coronectomy is that it reduces the risk of damage to the inferior alveolar nerve, which can cause numbness in the lower lip and chin. However, there are also risks associated with the procedure, including infection and the possibility that the roots may need to be removed at a later date.
