To describe a complication that occurs during the inferior alveolar nerve lateralization, which is applied due to residual bone height not enough for dental implant placement in standard sizes between the crest of the alveolar crest and the inferior alveolar canal, and to discuss surgical, phototherapy and pharmacological treatment approaches in the light of current data. A 34-year-old male patient who applied with a dental implant-supported fixed prosthetic restoration request had a transection of the inferior alveolar nerve during the lateralization application. In order to intervene in the complication, transposition of the inferior alveolar nerve was performed, and the free ends at the injury site were primarily passively sutured. Corticosteroid and low-dose laser treatments were applied in the postoperative period. Transposition techniques for the inferior alveolar nerve and related complications may occur for dental implant treatments. One of the complications that may occur during these techniques and may leave permanent sequelae in patients is nerve transection. One of the primary interventions that can be applied in the complication of transection is the primary approximation of the nerve endings. Corticosteroid and low-level laser treatments are recommended to support recovery in the postoperative period. Although detailed planning and precise surgical techniques are of great importance, nerve injuries are undesirable but possible complications of the interventions for the inferior alveolar nerve. However, agents that can suppress neuroinflammation in the early period and treatment options to support recovery should be considered to intervene in such complications.
