Coronectomy of lower impacted wisdom teeth is the partial removal of third molars, aiming to avoid inferior alveolar nerve injuries. The coronectomy procedure has several crucial points, such as the pulpal, periapical preoperative conditions of the tooth, the way of crown sectioning and decoronation, the wound closure and the length of patients' follow up. In addition it is important to identify and manage possible intraoperative or postoperative complications correctly. According to the literature, the complication rate of coronectomy is usually lower, than that of total teeth removal, furthermore considering inferior alveolar nerve injuries, coronectomy is significantly the safer procedure. The aim of the authors was to review the relevant literature, defining the indications, contraindications and the correct implementation of the coronectomy and to demonstrate the causes and incidences of failures and complications. Further aim was to promote the domestic acceptance of this procedure. Orv Hetil. 2017; 158(45): 1787-1793.
