What is Nerve Repositioning for Dental Implants?

Nerve repositioning, also called inferior alveolar nerve transposition, is a specialized surgical procedure that carefully moves the nerve in the lower jaw to create adequate space for dental implant placement. This advanced technique enables implant placement in patients with insufficient bone height above the nerve canal, avoiding the need for extensive bone grafting.

Nerve Repositioning Procedure

  1. Comprehensive nerve evaluation: 3D imaging to map exact nerve location and pathway
  2. Surgical access: Creating a window in the bone to expose the nerve canal
  3. Careful nerve mobilization: Gently freeing the nerve from the surrounding bone
  4. Nerve repositioning: Moving the nerve aside temporarily or permanently
  5. Implant placement: Installing dental implants in newly available space
  6. Nerve protection: Ensuring nerve is safely positioned and protected
  7. Closure and monitoring: Healing assessment and sensation monitoring

When is Nerve Repositioning Necessary?

  • Insufficient bone height above the inferior alveolar nerve (less than 7-8mm)
  • Patient unwilling or unable to undergo extensive bone grafting
  • Desire for a fixed implant solution over removable dentures
  • Adequate bone width but insufficient vertical height
  • Multiple missing posterior teeth requiring implant support
  • Cases where a sinus lift is not sufficient alone

What are the Benefits of Nerve Repositioning Surgery?

Nerve repositioning offers significant advantages for patients with severe bone loss in the lower jaw who still wish to have fixed, implant-supported teeth. The primary benefit is making implant placement possible in areas where conventional approaches would be impossible due to limited bone height above the nerve canal. This expanded treatment capability means more patients can enjoy the superior function and aesthetics that only dental implants can provide, even in challenging anatomical situations.

By allowing implant placement in the native jawbone, nerve repositioning often eliminates the need for extensive bone grafting procedures that would otherwise be required to build up sufficient height above the nerve. This can significantly reduce overall treatment time and cost while providing a more predictable foundation for long-term implant success.

From a quality of life perspective, nerve repositioning allows patients to receive fixed implant restorations rather than removable dentures, which can dramatically improve chewing efficiency, speech clarity, and confidence. The ability to place implants in the posterior (back) region of the lower jaw helps distribute bite forces more naturally, protecting remaining teeth and maintaining proper jaw function.

Frequently Asked Questions

Am I a Candidate for Nerve Repositioning?

Nerve repositioning is generally considered for patients who have significant bone loss in the lower jaw, particularly when the height of bone above the nerve canal is insufficient for conventional implant placement (typically less than 5-6mm). Ideal candidates are in good general health, non-smokers or willing to quit during the healing period, and committed to excellent oral hygiene. This procedure is typically recommended only after other options have been considered, as it does carry some risk of temporary or permanent altered sensation.

What Are the Alternatives to Nerve Repositioning?

Alternatives to nerve repositioning include vertical bone augmentation to build up bone height above the nerve, the use of shorter implants that can be placed without interfering with the nerve, or in some cases, implants placed in front of the nerve where more bone is typically available. Dr. Johnson will thoroughly discuss all appropriate options during your consultation, weighing the relative advantages and limitations of each approach for your specific situation.

Will I Have Permanent Numbness After the Procedure?

While temporary numbness or altered sensation in the lower lip and chin is expected following nerve repositioning, permanent changes are uncommon when the procedure is performed by a specialist with Dr. Johnson’s expertise. Most patients experience gradual improvement over several weeks to months, with complete or near-complete return of normal sensation. During your consultation, Dr. Johnson will discuss this risk thoroughly so you can make an informed decision about your treatment.
