Nowadays, oral implants are routinely used for rehabilitation of the edentulous mandible as this procedure is often considered uncomplicated, especially when limiting implant placement to the symphyseal area. Nevertheless, a case of nerve disturbance in the anterior mandible after the implant placement is described.
