Dr. Fabrizio asks:
I have a case where the mandibular nerve exited the mental foramen, but seems to continue mesially and connects with the
controlateral nerve in the incisor region.
The patient will be
edentulous and I am planning to place dental implants in the interforamina
area. I am wondering what are the consequences of invading the anterior
portion of the nerve. Any thoughts?

NanoGen is a nanotechnology-based bone graft. As compared to traditional calcium sulfate, NanoGen provides the stimulation for bone regeneration over a much longer period.

I would not recommend invading the nerve space in any region, you will always increase your risk of a post operative parasthesia. What type of radiographic studies are you using? Hopefully you have a recent CT. If the nerve truly runs the entire length of the mandible and connects with the contralateral nerve you have three choices: nerve transpotion, short fixtures(endopore)or alternate treatmen plan that does not include implant placement.
The nerves that you observed on your radiographic examination are the incisive nerves. The incisive nerve is the terminal branch of the inferior alveolar nerve which continues within the anterior body of the mandible to provide sensation to the mandibular anterior teeth. This nerve and its companion artery and vein are not often seen on a radiograph. Theoretically, this nerve does not provide sensation to any soft tissues in the anterior region of the mandible. With extraction of the mandibular anterior teeth, the incisive nerve no longer has any function. This is similar to the dental branches of the inferior alveolar nerve that are non-funciotnal after extraction of posterior teeth.
I totally disagree with 2nd post.
What parasthesia?
Parastheia of teeth which are no longer in mouth?
Whether you see it or not with your nacked eye, incisive nerve is always present in anterior mandible.
Just because you are able to recognize on X ray does not make it different.
And it is taught in our anatomy classes that contralateral branches of incisive nerve are connected at mid line.
IT IS A NON FUNCTIONAL NERVE.
as a matter of fact during IAN repositioning procedure incisive nerve is intentioally cut to relieve tention on IAN.
Just make sure there is no loop formation of Mental nerve.
Thanks for all the valuable inputs
