The invention is a tool that can measure an edentulous ridge and properly locate and or verify new planned dental implant positions. Due to the innovative design of the offset or curved shanks, the invention allows proper positioning of the Perio-Implant Ridge Probe instrument against existing teeth or implants while measuring an edentulous ridge. The invention consists of five separate design types of Perio-Implant Ridge Probes. Each type is an independent instrument with a variation in the design at the working end. The design innovation is in the design of the shank, the ridge probe, and the design of the double ended instruments. The ridge probe is calibrated with millimeter markings and colored bands delineating potential implant locations. The offset shank type design provides for measurements to be attained from either end of the ridge probe. The double ended instruments provide for improved instrument utility.
