<p>The device for reproducing a bone relief by tridimensional ultrasound echography is comprised of the combination of a generator receiver (2) fitted with a ultrasound probe (1) intended to measure by echography the thickness of soft tissues which cover a bony area, a computer (4) for storing measurement values and visualizing the bony relief in three dimensions on a monitor display screen (3), and a programmable machine tool (5) which reduces a plaster model of the studied zone by a thickness corresponding (7) to the soft tissues and thus provides a plaster model (6) of the underlying bone relief. This technique, intended to the making of bone prints, particularly in dentistry and implantology, allows to achieve ''juxta-bony'' implants by suppressing the bloody print of the bone, owing to the tridimensional image obtained by visualizing bone relief through teguments and muscles by means of ultrasound probes.</p> |
