Nerve repositioning

Nerve repositioning or Nerve Lateralization is a technique that is performed when a patient has missing teeth in the posterior area of the lower jawbone and requires dental Implants. This technique is only necessary in the case that has lost significant amounts of lower jawbone since it is not possible to place implants without damaging the nerve. To address this problem, an oral surgeon can drill a small window in the bone and move the nerve to one side. The implants then can be placed through the bony canal previously filled by the nerve.



 

  • The surgeon will reflect the tissue and make a small window to gain access to the neurovascular bundle inside the jawbone. 
  • The surgeon will reflect the tissue and make a small window to gain access to the neurovascular bundle inside the jawbone. 
  • The implant is inserted into the bone,while the neurovascular bundle is kept out of its path.
  • Once placed, the bundle is released and the access site is refilled with bone graft materials. 

 


Lateralization of the inferior alveolar nerve offers the following advantages

  • Implants of greater length can be placed in the same surgical step. 
  • Greater primary implant stability is afforded thanks to the possibility of bicortical mandibular fixation. 
  • Only a physical examination and simple radiological study (e.g., panoramic X-rays) are needed. 
  • Increased protection of the dental neurovascular bundle is afforded during implant placement .
  • No advance bone grafting is needed, and donor site morbidity is avoided.
