In some cases, severe bone resorption occurs following tooth loss, making it impossible to place implants without damaging the inferior alveolar nerve. In such cases, apart from onlay bone grafting to achieve sufficient ridge height, another option is to remove the inferior alveolar nerve from its canal laterally using the lateralization or transposition technique. In this case report, we evaluate the short-term prognosis of inferior alveolar nerve function following immediate implant placement during nerve reposition. Case: After clinical and radiographic examinations of a 36-year-old female patient without any systemic disease, the distance between the alveolar crest and the inferior alveolar nerve was found to be insufficient to prevent the use of an implant of the desired length due to bilateral resorption in the posterior mandible. The patient was informed about possible sensory changes that may occur after the operation. Following the crestal incision extending from the retromolar pad to the canine region, vertical relaxing incisions were made. The mucoperiosteal flap was lifted and the mental foramen and neurovascular bundle were carefully exposed. A vertical osteotomy line of 5-7 mm in length was obtained from the distal of the mental foramen. The posterior vertical osteotomy was also performed approximately 15 mm posteriorly at the level of the second molar. Care was taken that all osteotomy incisions included only the outer cortical layer and partially the cancellous bone. In this patient, for whom we applied the lateralization technique after the separation of the bone window from the mandible, the implant cavity was prepared while the nerve was temporarily positioned laterally without causing excessive tension in the N. alveolaris inferior, to which we applied tensile force. After the cancellous bone particles obtained from the inner surface of the bone window opened on the placed implant surface, they were covered with a 20x20mm collagen membrane. Inferior alveolar nerve was released and after the re-adaptation of the bone window that was kept in physiological saline, mucoperiostal lambo was sutured with 4.0 prolene suture. Post-op paresthesia seen in the early period decreases by 90% and post-op. It was observed as hypoesthesia in the 3rd month. Discussion & Conclusion: Implant placement in the lingual, superior, vestibule, or mesial foramen mentale of the neurovascular bundle in the highly resorbed posterior mandible is a complicated procedure, requires extensive radiographic examinations, and carries a high risk of nerve trauma. Although inferior alveolar nerve transposition is less invasive, it should be considered that this technique does not correct the distance between the arches and the risk of permanent damage to the nerve bundle is high.}, number={1}, publisher={Meffert İmplant Enstitüsü}
