ABSTRACT:
An electronic system for determining the density and structure of bone tissue and stimulating osteogenesis in dentistry, having a diagnosis system for injecting an ultrasonic signal U(t) into a bone portion and analyzing the ultrasonic signal received after traveling through the bone portion to determine a number of characteristic data items of the signal describing physical and structural characteristics of the bone tissue. The diagnosis system performs a number of measuring steps to determine and memorize a set of characteristic data items describing progress of a bone growth process and/or a bone repair process following extraction of a tooth and/or placement of a dental prosthesis in the bone portion. The system also has an osteogenesis stimulation system for directing an ultrasonic stimulation signal onto the bone portion to promote the bone growth and/or bone repair process.
