Understanding Nerve Repositioning: When and Why It’s Needed
In cases where there has been substantial bone loss in the lower jaw, traditional dental implants may not be possible due to the inferior alveolar nerve—responsible for sensation in the lower lip and chin. When bone height is insufficient, nerve repositioning, also known as nerve lateralisation, is a specialised technique that involves relocating the nerve to a safer position, allowing for the placement of longer and more stable implants.
This procedure is particularly beneficial for patients needing implants in the back portion of the lower jaw, where bone height is often insufficient. Without nerve repositioning, attempting to place implants could result in nerve damage, leading to numbness or altered sensation in the lower lip and chin.
By relocating the inferior alveolar nerve carefully, implantologists can maximise the available bone height, making it possible to place secure, long-lasting implants without affecting nerve function. This procedure can be a more efficient option compared to extensive bone grafting, providing a more direct path to restoring missing teeth in the lower jaw.
Key Steps in the Nerve Repositioning Procedure
- Initial Evaluation & Planning – A detailed 3D CT scan and digital imaging are used to evaluate the bone height and nerve positioning.
- Incision & Bone Access – A precise incision is made along the lower jaw to access the inferior alveolar nerve in its natural canal.
- Careful Nerve Repositioning – The nerve is gently moved sideways to create sufficient space for the implant placement.
- Implant Placement & Bone Cushioning – Depending on the case, the dental implant may be placed immediately or in a later procedure.
- Bone Grafting for Stability – Bone grafting material may be used to provide extra support and enhance implant integration.
- Healing & Recovery Period – A healing phase of 2 to 3 months allows the implant to integrate and the nerve to adapt before the final prosthetic is attached.

Nerve in Jaw Bone: Recovery, Risks, and Outcomes
While
✅ Alternative to Extensive Bone Grafting – This procedure can replace complex bone grafting in cases of significant bone loss.
✅ Potential Sensory Changes – Some patients may experience altered sensation, such as mild tingling or prolonged numbness, although function typically returns to normal.
✅ Expertise is Key – Choosing an experienced implantologist is essential to minimise risks and ensure precise nerve handling throughout the procedure.
