Understanding Nerve Repositioning: Purpose and Necessity
Significant bone loss in the lower jaw can make conventional dental implants unfeasible due to the position of the inferior alveolar nerve, which controls sensation in the lower lip and chin. When there isn’t enough bone height, nerve repositioning (or lateralisation) is a specialised surgical technique that involves carefully relocating this nerve to allow for the placement of longer, more secure implants.
This procedure is especially recommended for patients requiring implants in the posterior lower jaw where bone deficiency prevents safe implant placement. Without nerve repositioning, implant placement risks damaging the nerve, potentially causing numbness or altered sensations.
By delicately moving the inferior alveolar nerve, implantologists at Smilo Dental Implants Cardiff maximise available bone height, facilitating strong, durable implants without compromising nerve function. Though complex, this approach can avoid more extensive bone grafting, providing a more direct path to restoring missing teeth in the lower jaw.
Key Stages of the Nerve Repositioning Procedure
- Initial Assessment & Planning: Detailed 3D CT scan and digital imaging assess bone dimensions and nerve location.
- Incision & Access: A precise incision grants access to the nerve within its bony canal in the lower jaw.
- Careful Nerve Lateralisation:The nerve is gently moved aside to create sufficient space for implant placement.
- Implant Insertion & Bone Support: Depending on the case, implants may be placed immediately or later, with bone grafting applied as needed.
- Bone Grafting: Additional bone material is often used to stabilise the site and promote healing.
- Recovery & Healing: A 2-3 month period allows for implant integration and nerve adaptation before final prosthetic restoration.

Recovery, Risks & Outcomes of Nerve Repositioning
Nerve repositioning is a specialised procedure with unique considerations. Recovery is critical for implant success and nerve function. Most patients experience temporary numbness or tingling in the lower lip and chin, which usually improves over several months as the nerve adjusts.
Important factors before considering nerve repositioning:
✅ Alternative to Extensive Bone Grafting: This technique can reduce or eliminate the need for complex grafts in cases of severe bone loss.
✅ Sensory Changes: While nerve sensation typically returns to normal, some patients may experience prolonged altered feeling or numbness.
✅ Expertise is Key: Selecting a highly skilled implantologist minimises risks and ensures careful nerve management.
