Abstract: An insert assembly has an insert having an insert metal tang, and a radiofrequency identifier having a ferromagnetic layer in contact with the insert metal tang and including ferromagnetic material, a dielectric layer in contact with the ferromagnetic layer, an insert antenna in contact with the dielectric layer and having an insert antenna metal element extending along a planar profile for receiving and transmitting electromagnetic fields, and an identification chip operatively connected to the insert antenna for transmitting and receiving information about the insert assembly. The ferromagnetic layer reduces or cancels attenuation and/or distortion phenomena of electromagnetic fields. A transceiver device puts the identification chip in wireless communication with a handpiece antenna. The identification chip avoids protruding from a first or outer side of the planar profile. A part of the identification chip protrudes with a chip portion from a second or inner side of the insert antenna metal element.

Abstract: An ultrasonic cutting device for osteotomy is provided. The device has a blade extending in a longitudinal direction, an attachment member connected through an extension member with a handpiece configured to generate vibrations. The attachment member is connected to a proximal end of the blade which has a plurality of cutting elements formed on a distal portion thereof. The cutting elements have an arcuate portion arranged at a free end of the distal portion in the longitudinal direction and the arcuate portion has a continuous cutting edge with a plurality of triangular shaped teeth on opposite sides of the blade. The overall configuration of the distal portion of the blade is symmetrical relative to the longitudinal axis and progressively widens from the arcuate portion towards the proximal portion of the blade in the portion where the teeth are formed.

Abstract: A powder-cleaning device for dental use is provided. It has proximal arm configured for attachment to a source of compressed air; a distal arm having a distal end configured for dispensing a mixture of air and powder to a patient a turbulence chamber, which has a loading side door configured for insertion of an abrasive powder into the chamber according to a loading direction substantially orthogonal to a plane defined by the prevailing extensions of the arms (DP, DD). The turbulence chamber is interposed between the proximal arm and the distal arm and in fluid communication with both in such a way that the compressed air can be adducted in the turbulence chamber through the proximal arm and a mixture of air and powder can escape therefrom within the distal arm. A controller is also provided for compressed air flow, arranged on the proximal arm upstream of the turbulence chamber.

Abstract: An ultrasound resonant dipole or sonotrode (3) for medical applications includes: a tang (30, 31, 32) designed to be connected to a handset including an utrasound transducer (1) that vibrates at ultrasound frequency with a longitudinal axis of vibration (X-X) coaxial with the axis of the tang, an annular element (33) connected to the tang, and a tool (5) disposed on the annular element (33) connected to the tang, and a tool (5) disposed on the annular element (33) with an axis of vibration (Y-Y) inclined with respect to the axis of vibration (X-X) of the transducer. The annular element (33) is discontinuous and has an aperture (34).
