A device for guiding a cutting tool capable of cutting bone portions at the level of the head of a bone includes a seat intended to be fastened at the level of said head defining a first rotation axis (&#x393;). The device includes means for adjusting the position of the first rotation axis with respect to said seat and an arm, with one end of said arm being pivotally assembled on said seat according to the first rotation axis. A guide intended to support the tool is pivotally assembled on the arm according to a second rotation axis (&#x394;).

Guiding device for bone cutting

The invention relates to a method for the determination of the position of a radiographic or radioscopic unit () with relation to a reference point (R) on producing a radiographic image of an object (). The position of the unit () with relation to a reference point (R) is determined from the determination of the position of a test pattern (), with relation to the unit (), which is mechanically fixed to the object, by using the image of the test pattern with relation to the reference point (R). The invention further relates to a determining device for carrying out said method.

A system of transfer of a simulated position of a dental implant from an X-ray scanner to a robot for drilling a cradle of reproduction, in complementary shape, of a dental casting. The system includes at least one mechanical support and means adapted to removably connecting in a reproducible position the cradle to the support, the cradle containing at least two rectilinear non-concurrent elements visible by X-rays.
