Coronectomía en terceros molares inferiores

The lower third molar extraction is one of the most common procedures in the field of oral surgery. Furthermore, the damage of the inferior alveolar nerve is one of the most frequent complications related to this procedure. The coronectomy was introduced in 1984, as an alternative approach that tended to reduce the occurrence of this complication. The main objective of this article is to review current evidence of coronectomy applied to mandibular third molars, analyzing indications, contraindications, complications and success of the technique. The coronectomy seems to be an effective alternative to conventional third molar extraction, for the prevention of neurosensorial disorders in impacted third molars in direct relation with inferior alveolar nerve. However, further studies are needed which compare conventional approach with coronectomy with a greater follow-up to understand the long-term morbidities and success of the technique.
