• Introduction: Due to the close relationship of the third molar roots with the inferior alveolar nerve (IAN), involvement of this nerve is one of the common postoperative disorders. As an alternative to the extraction, a new procedure called coronectomy was introduced in 1984. The aim of this work is to perform a systematic review of the literature in order to know the results and complications of third molar coronectomy in relation to the IAN in order to verify if it is an adequate procedure.

  Material and methods: A literature search was conducted in the Medline, Ebsco, Cochrane, Clinicaltrials and Sigle databases from 2000 to 2017.

  Results and discussion: After applying the inclusion and exclusion criteria, 17 articles were analyzed, with a lower percentage of IAN lesion in the coronectomy procedure, as well as a lower indcidence of infection and dry socket compared to extraction.

  Conclusion: It has been observed that the coronectomy procedure at the level of the lower third molars is a predictable procedure with few complications.
