PDF: Coronectomy - Indications, Outcomes, and Description of Technique

Coronectomy was first described by Ecuyer and Debien in 1984 as an alternative procedure to traditional extraction of third molars.

Several reports have been published since regarding the technique, indications, efficacy, and outcome of this procedure.

Most recently, it has been investigated as an alternative to traditional surgical extraction of third molars, particularly for those with an increased risk of damage to the inferior alveolar nerve (IAN). 

Several studies have demonstrated that coronectomy does significantly decrease the risk of iatrogenic injury to the IAN, with some studies also suggesting a lower complication rate.

Coronectomy is considered a reasonable and safe treatment alternative for patients who demonstrate elevated risk for injury to the inferior alveolar nerve with the removal of third molars.

The procedure has been documented in the oral and maxillofacial surgery literature as a treatment alternative to extraction of third molar in patients considered at elevated risk for permanent nerve injury.

Coronectomy is particularly appropriate for patients who are older than 25 years and who report low tolerance for the possibility of posttreatment neurosensory deficit at the consultation.

This article discusses the indications for coronectomy, the author’s technique, and the complications and outcomes of this procedure.
