Currently, several techniques are used in the posterior mandible to increase alveolar bone height and width. However, each 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 total, 26 implants were successfully placed lateral to the IAN in 16 patients and restored with splinted screw-retained prostheses. The postloading follow-up time ranged between 3 months and 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 that was reduced after implant removal but remained in a small area on the left corner of her lip.
