The inferior alveolar nerve which gives feeling to the lower lip and chin may need to be moved in order to make room for placement of dental implants to the lower jaw. A nerve repositioning procedure is limited to the lower jaw and indicated when teeth are missing in the area of the two back molars and/or and second premolar, with the above-mentioned secondary condition. Since this procedure is considered a very aggressive approach (there is almost always some postoperative numbness of the lower lip and jaw area, which dissipates only very slowly, if ever). Usually other, less aggressive options are considered first (placement of blade implants, etc.).
