Understanding Nerve Repositioning: When and Why It’s Needed
When patients experience significant bone loss in the lower jaw, traditional dental implants may not be feasible due to the presence of the inferior alveolar nerve—the nerve responsible for sensation in the lower lip and chin. In cases where bone height is insufficient, nerve repositioning (also known as nerve lateralisation) is a specialised procedure that allows for the placement of longer, more stable implants by safely moving the nerve to a more favourable position.
This technique is most commonly recommended for individuals who require dental implants in the back of the lower jaw but do not have enough bone height to accommodate traditional implants. Without repositioning the nerve, attempting to place implants in these areas could risk nerve damage, which can lead to numbness or altered sensation in the lower lip and chin.
By carefully relocating the inferior alveolar nerve, implantologists can optimise the available bone height, allowing for secure, long-lasting implants without compromising nerve function. This advanced procedure can often eliminate the need for complex bone grafting, providing a more efficient and direct approach to restoring missing teeth in the lower jaw
Key Steps in the Nerve Repositioning Procedure
- Initial Evaluation & Planning – A thorough 3D CT scan and digital imaging are performed to assess the bone height and the position of the nerve.
- Incision & Bone Access – A precise incision is made along the lower jaw to access the inferior alveolar nerve within its natural canal.
- Careful Nerve Repositioning – The nerve is gently and strategically moved sideways to create sufficient space for implant placement.
- Implant Placement & Bone Cushioning – Depending on the individual case, the dental implant may be placed immediately or in a subsequent procedure.
- Bone Grafting for Stability – Bone grafting material may be added to the site to further support implant integration and ensure long-term stability.
- Healing & Recovery Period – A 2 to 3-month healing phase follows to allow the implants to integrate and the nerve to recover before the final prosthetic (crown or bridge) is placed

Nerve in Jaw Bone: Understanding Recovery, Risks & Outcomes
Nerve repositioning is a highly specialised procedure, and while the risks are minimal with the right care, there are a few important considerations before proceeding. The recovery process is essential for successful implant integration and nerve adaptation. During healing, many patients experience temporary numbness or tingling in the lower lip and chin, but this typically improves over time as the nerve adjusts to its new position.
Key factors to consider before opting for nerve repositioning:
✅ Alternative to Extensive Bone Grafting – This technique can often eliminate the need for complex bone grafting in cases of significant bone loss.
✅ Potential Sensory Changes – While nerve function generally returns to normal, some patients may experience altered sensation, from mild tingling to prolonged numbness.
✅ Expertise Matters – It’s essential to choose an experienced implantologist to reduce risks and ensure precise nerve handling during the procedure.
