Understanding Nerve Repositioning: Why and When It’s Necessary
When there is significant bone loss in the lower jaw, traditional dental implants may not be possible due to the presence of the inferior alveolar nerve, which provides sensation to the lower lip and chin. In these cases, nerve repositioning (also known as nerve lateralisation) is an advanced procedure that allows for the placement of longer and more stable implants by safely relocating the nerve to a more secure position.
This technique is typically recommended for individuals who require implants in the posterior region of the lower jaw but do not have sufficient bone height. Without nerve repositioning, attempting to place implants could result in nerve damage, leading to numbness or altered sensation in the chin and lower lip.
By carefully repositioning the inferior alveolar nerve, implant specialists can optimise the available bone height, making it possible to place secure, long-lasting implants without risking nerve function. This method is often preferred over extensive bone grafting, offering a more efficient and direct solution to restoring missing teeth in the lower jaw.
Key Stages of the Nerve Repositioning Procedure
- Initial Assessment & Planning – We begin with a detailed 3D CT scan and digital imaging to evaluate the bone height and the positioning of the nerve.
- Incision & Bone Exposure – A small incision is made in the lower jaw to provide access to the inferior alveolar nerve within its natural canal.
- Nerve Repositioning – The nerve is carefully and precisely moved to the side, creating enough room for the placement of dental implants.
- Implant Placement & Bone Support – Depending on the case, the dental implant may be placed immediately, or a follow-up procedure may be scheduled.
- Bone Grafting for Stability – Bone grafting material is often added to support the surgical site, ensuring proper implant integration and healing.
- Healing & Recovery Period – After the procedure, a healing phase of 2 to 3 months is required for implant integration and nerve recovery before the final restoration (crown or bridge) is attached.

Nerve in Jawbone: Recovery, Risks, and Expected Outcomes
While nerve repositioning is a specialised procedure, it’s essential to understand the recovery process and potential risks. Most patients experience temporary numbness or tingling in the lower lip and chin, which improves gradually as the nerve adjusts to its new position.
Important factors to consider before opting for nerve repositioning include:
✅ An Alternative to Extensive Bone Grafting – For cases of significant bone loss, nerve repositioning may eliminate the need for complex bone grafting procedures.
✅ Potential Sensory Changes – While most patients regain normal nerve function, some may experience mild tingling or prolonged numbness.
✅ The Importance of Expertise – Choosing a skilled implant specialist is crucial for minimising risks and ensuring precise handling of the nerve during the procedure.
