Severely resorbed lower mandible: implant locator overdenture?

Last Updated September 20, 2020

This is the most resorbed mandible I have ever had to deal with and wondering whether I could help the patient out by placing 2 anterior implants for a 2 implant locator over-denture. However the bone has resorbed to the point the IAN is exposed, and I can’t even locate the mental foramen! Patient has seen the oral surgeon and has ruled out any major block grafting etc. As per my planning, there is just enough room for implant in the LR2 LL2 area, but I would have to impinge into the anterior branch of the IAN. As the CBCT scan is not clear on where the mental foramen is due to the severe resorption, will my current implant position give a good safe zone to not impinge on the mental nerve? Thanks for all your thoughts.
