Currently, there are several techniques being used in the posterior mandible to increase alveolar bone height and width. However, each of these has potential complications and limitations. The purpose of the current study was to present the surgical technique and restorative considerations for implant placement lateral to the inferior alveolar nerve (IAN) in cases of severely atrophic edentulous posterior mandibles. In the current study, 26 implants in 16 patients were successfully placed lateral to IAN and restored with splinted screw-retained prostheses with a follow-up time after loading ranging from 3 months to 6 years. Two patients reported complications. One patient had a temporary paresthesia that resolved 3 months after implant placement and the second patient had minor paresthesia which was reduced after implant removal but remained in a small area on the left corner of her lip.
