Objective: After long-term edentulism, advanced bone resorption occurs and the amount of bone above the inferior alveolar nerve is not sufficient for implant placement.In such cases, various methods can be used. These; short implant applications, onlay autogenous grafting methods can be used.On the other hand, by relocating the inferior alveolar nerve, sufficient distance can be obtained and the implant can be applied.
Case: A 43-year-old female patient without any systemic disease was admitted to our clinic due to partial edentulism.As a result of clinical and radiographic examinations, the bone distance between the inferior alveolar nerve and the alveolar crest was found to be insufficient, which would prevent the application of the ideal length implant due to bone resorption in the left posterior mandible. An incision extended from the middle of the alveolar crest to the retromolar region was made.The flap was relieved by making a vertical incision anteriorly. A lateral wındow ıs created usıng a pıezo devıce.The mental foromande was included in this window and the inferior alveolar nerve was positioned more laterally towards the opening window. Implants were placed in the area by gently holding the lateralized inferior alveolar nerve. The inferior alveolar nerve was released and the removed bone window was replaced after re-adaptation. Postoperative controls continue.
Conclusion: In the highly resorbed posterior mandible, implant treatment with inferior alveolar nerve reposition has many advantages such as shortening the treatment time and allowing longer implant placement. However, this technique carries the risk of high nerve trauma.
