The development of dental medicine has increased the awareness of the importance of a healthy oral cavity. The cognizance of possible legal actions caused by both complications and mistakes by dental practitioners reduces the probability of litigation. Therefore, dental interventions, especially complicated tooth extractions, should be approached with the utmost caution. The lower teeth are specific because of their proximity to the mandibular canal. Lack of attention or bad judgment by the dental practitioner can lead to temporary or permanent injury to the patient. The most common problem is the impaction of the third molars which is treated with the alveotomy. Recently, procedures that avoid contact with the mandibular canal, such as coronectomies or partial odontectomy, are used more frequently. With these procedures, especially coronectomy, the root of the tooth is left in the bone, whilst avoiding the contact with the mandibular canal, when removing the crown of the tooth. Before the procedure itself, it is crucial to perform a radiological diagnosis with orthopantomogram (2D) and CBCT (3D) to determine the exact position of the teeth in the mandible. Although still somewhat repudiated by the profession, the fact is that coronectomy causes fewer postoperative complications compared to standard alveotomy.
