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 viable due to the presence of the inferior alveolar nerve—the nerve responsible for sensation in the lower lip and chin. In cases where the 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 carefully moving the nerve to a safer position.
This technique is primarily recommended for individuals who need dental implants in the back portion of the lower jaw but lack the necessary bone height to support them. Without repositioning, attempting to place implants in these areas could lead to nerve damage, resulting in numbness or altered sensation in the lower lip and chin.
By carefully relocating the inferior alveolar nerve, Dental implantologists can maximise the available bone height, allowing for secure, long-lasting dental implants without compromising nerve function. While this is an advanced procedure, it can eliminate the need for extensive bone grafting, offering 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 conducted to assess bone height and nerve positioning.
- Incision & Bone Access – A precise incision is made along the lower jaw, allowing access to the inferior alveolar nerve within its natural canal.
- Careful Nerve Repositioning – The nerve is gently and strategically moved sideways to create enough space for 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 – To further reinforce the surgical site, bone grafting material is often added to support implant integration and healing.
- Healing & Recovery Period – A 2 to 3-month healing phase follows, allowing implant integration and nerve recovery before the final prosthetic (crown or bridge) is attached.

Nerve in Jaw Bone: Understanding Recovery, Risks & Outcomes
While nerve repositioning is a highly specialised procedure, it comes with unique considerations that patients should be aware of before proceeding. The healing process plays a crucial role in ensuring successful implant integration and nerve adaptation. Most patients experience temporary numbness or tingling in the lower lip and chin, which gradually improves over the following months as the nerve adjusts to its new position.
Key factors to consider before opting for nerve repositioning:
✅ Alternative to Extensive Bone Grafting – In cases where bone loss is significant, this method can eliminate the need for complex bone grafting procedures.
✅ Potential Sensory Changes – While nerve function often returns to normal, some patients may experience altered sensation, ranging from mild tingling to prolonged numbness.
✅ Expertise Matters – Choosing an experienced implantologist is crucial for reducing risks and ensuring precise nerve handling during the procedure.
