摘要：The surgery of impacted third molars has become frequent in the routine of oral and maxillofacial professionals. Coronectomy or partial intentional odontectomy is a surgical procedure in which the dental crown is removed and the roots belonging to this element are left in the dental alveolus. This method aims to preserve the inferior alveolar neurovascular bundle, which exists in the mandibular canal, in cases where the dental root is in close contact with it. The surgical technique of intentional partial odontectomy consists in removing the coronal portion of the tooth 1 to 2 mm below the cemento-enamel junction. Two important points of the technique is that no enamel remains in the dental fragment that will be buried and that it is retained at least 3 mm apical to the alveolar bone crest. As it is a specific surgical technique, the indications for partial odontectomy are restricted to the prevention of lesions to the inferior alveolar nerve, in which the root of the third molar is in close contact with the nerve. This study performed a literature review on the technique of intentional partial odontectomy, its history, technique, indications, contraindications, complementary exams and complications. Partial intentional odontectomy is a viable alternative technique with the purpose of preventing damage to the nerve structures during the exodontia of unerupted mandibular third molars. One of the complications of the procedure is the migration of the remaining roots, but reintervention to remove them can be considered part of the treatment.
