Abstract

Background: Neurological damage may occur during a third molar extraction procedure when the tooth root is near the mandibular canal. Although the incidence of this complication is low, a great range of variability has been reported in the literature. Several methods to reduce or eliminate this complication have been proposed, such as orthodontic-assisted extraction, extraction of the second molar, or an intentional odontectomy. Objective: The objective of this case report is to present a low risk extraction procedure: a coronectomy with forced eruption (COFE) to avoid potential neural damage when removal of lower wisdom tooth compressing inferior alveolar nerve in our daily practice. Study Design: Case report. Materials and Methods: A 15-year-old male patient was referred from a dental clinic for bilateral extraction of impacted mandibular third molars. The initial computed tomographic scan showed the intimate relationship between the teeth and the inferior alveolar nerve. In order to prevent nerve injury, the COFE technique was used. This procedure consisted of the surgical removal of the crown portion to create a space. Then the root was protracted by power tubing. The patient returned to the hospital every 4 weeks to change the power tubing. Results: The roots of the third molar were moved a distance from the mandibular canals by orthodontic force after 4 months. Then the roots were successfully removed with no neurological consequences. Conclusion: Removal of an impacted lower third molar with the COFE technique can offer a successful method to prevent neurological damage for cases of a compressed inferior alveolar nerve.
