Abstract: Device for the regeneration and prevention of degeneration of the cartilage and subchondral bone and the proliferation of chondrocytes by means of electromagnetic waves comprising a device for generating a periodic signal u(t) and a power amplifier suitable for applying the signal u(t) to a pair of solenoids for the generation of an electromagnetic field M(t) addressed towards a portion of human/animal body containing cartilage. Setting means are provided for the generation of an electromagnetic field having intensity between 0.2 and 2 milliTesla, frequency between 37 and 75 Hz and period of application between 1 hour and 9 hours.

Abstract: Electromagnetic field stimulator device in which a current generator device supplies a solenoid with current the waveform of which includes the repetition of a ramp having a certain slope. This current causes the generation of an electromagnetic field that induces on a control probe irradiated by the electromagnetic field, an induced voltage of markedly constant amplitude during the ramp-like linear growth period of the current. This electromagnetic field is used to preserve the integrity of articular cartilage subject to degeneration.

Abstract: Device for the regeneration and prevention of degeneration of the cartilage and subchondral bone, the proliferation of chondrocytes and for blocking or reducing the fibroblastic evolution of chondrocytes and mesenchymal cells by means of electromagnetic waves comprising a device for generating a periodic signal u(t) and a power amplifier suitable for applying the signal u(t) to a pair of solenoids for the generation of an electromagnetic field M(t) addressed towards a portion of human/animal body containing cartilage. Setting means are provided for the generation of an electromagnetic field having intensity between 0.5 and 2 milliTesla, frequency between 37 and 75 Hz and period of application between 1 hour and 9 hours.

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.
