An ultrasonic orthodontal monitoring system and method of use is described herein, featuring an intraoral ultrasonic transducer and an ultrasonic monitoring apparatus configured to connect to the intraoral ultrasonic transducer, generate and send electrical pulse signals to the intraoral ultrasonic transducer, receive measured signals from the intraoral ultrasonic transducer, and generate time-of-flight and relative density based on the measured signals. This invention will permit routine measurements to be made of osseointegration by the patients dentist during regular maintenance appointments, thereby reducing the risk of a failed implant, patient discomfort, and inconvenience. As a diagnostic tool, it can also aid in the diagnosis and treatment of progressive periodontal disease, peri-implantitis, and osteoporosis in edentulous patients.
