Clinical and radiological results of coronectomy of the third molars adjacent to the mandibular canal: case series

A method of performing a coronectomy is presented as an incomplete extraction of the third lower molars. The described technique is based on the prevention of damage to the structures of the mandibular canal in cases of their close interposition with the tooth, and also helps to reduce the time of intervention and its invasiveness. In 3 clinical cases, the features of the postoperative period and the X-ray picture of this surgical treatment method were demonstrated. Results. Of the 22 coronectomy operations performed on the lower third molars, none showed signs of damage to the inferior alveolar nerve. There were no signs of wound dehiscence, pulpitis, or the development of an infectious and inflammatory process in the postoperative area in all patients associated with coronectomy surgery. In one case (5%), repeated intervention was performed — extraction of the roots due to their eruption into the oral cavity.
