The presented case represents how the lack of a preoperative panoramic radiograph or any radiograph contributed to incorrect case planning, poor implant selection, and the careless surgical placement of an implant into or dangerously close to the lower left mental foramen, resulting in a paresthesia of 9 months duration. Two implants were surgically removed and the bone defects were grafted with a mixture of irradiated cancellous bone plus Biogran. One implant was sectioned and intentionally “put to sleep.” The case was successfully completed with a lower bar overdenture supported by 4 screw implants placed in alternate sites, opposing a custom fabricated maxillary denture with a lingualized occlusal scheme.
