A multi-piece apparatus for performing dental hygiene includes a head portion including a concave support member; a floss attachment; and a tapered hollow water access portion. The hollow water access portion includes a water intake component continuous with a water exit component. A mechanism is connected to the head portion that reduces bacteria from the head portion. A handle portion is connected to the head portion and includes a first handle end; a second handle end; and a fluid aqueduct extending an entire internal length of the handle portion, wherein the fluid aqueduct is aligned with the water intake component and extends within the head portion. A hose is connected to the handle portion, wherein the hose is positioned to direct water to traverse through the fluid aqueduct.

The invention provides for a dental or surgical handpiece with an elongated handle sleeve (110) and a head piece (50) attached to the front end of the handle sleeve (110) that serves to to detachably receive a dental tool as well as for a clamping mechanism (20) formed in the head piece (50) to detachably hold the tool, the clamping mechanism (20) having a push-button (10) for actuating the clamping mechanism (20). The handpiece further has an RFID transponder (5) for identifying the handpiece. The push-button (10) consists of a heat-insulating electrically non-conductive plastic or m ceramic material with a plate-shaped recess that holds the RFID transponder (5). The push-button (10) has a flat round shape so that the RFID transponder (5), because of the equally flat round shape of its coil, can be integrated very well into it. Particularly advantageous ambient electrical conditions can be achieved for the RFID transponder as the push-button (10) is made of an electrically non-conductive material. An advantageous thermal insulation is provided as the push-button (10) is made of a heat-insulating material.

A guided handpiece, system, and method to perform image guided surgery for dental implants. Conventionally an image guided surgery system needs a surgical guide, a handpiece, a set of guided drills and drill adaptors. Extended drills must be specifically designed and made for implant brands and parameters. Adaptors are required to accommodate drills of different diameters. The process is much more complex than freehand surgery while surgical guides are not used. This invention introduces a guided handpiece, corresponding system, and method, which overcome the problems of prior art and make it possible to perform guided surgery with regular drilling tools.

Described herein is a dental material applicator system comprising a segmented capsule and handpiece. The capsule separately holds a powder and a liquid such that upon activation in the handpiece by an operator, the powder and liquid are mixed into a paste. The operator then triggers the handpiece so that the mixed paste is extruded.

A handpiece assembly for a medical device has a handpiece having a handpiece distal portion for receiving an insert assembly including a radiofrequency identifier, an insert antenna and an insert. A handpiece antenna is arranged in the handpiece distal portion. Radiofrequency signal supply means provide radiofrequency signals to the handpiece antenna that communicates with the insert antenna when the insert assembly is inserted in an insertion region in the handpiece distal portion. The handpiece antenna is a loop antenna or segmented ring antenna having at least two segments. A first end of a first segment is connected to a first terminal of the radiofrequency signal supply means, a second end of a last segment is connected to a second terminal of the radiofrequency signal supply means, forming a coil radiating structure generating an electromagnetic field. Each segment has a radiant metal element, with respective inductance, electrically connected to a respective capacitive element. A medical device including a control element, an insert assembly, and the handpiece assembly is also provided.

The invention relates to a handpiece (100) for a medical or cosmetic processing device, having: a connection line (102) at a connection end (101); and a housing (104) in which a receiving area is provided between the connection end (101) and the processing end (103), a rotary drive unit being receivable in said receiving area in order to drive a rotary tool (210) which can be attached to the processing end (103). The invention is characterized in that the handpiece (100) can be separated from the connection end (101), wherein the handpiece (100) is designed such that the motor (110) remains on the connection end (101) after uncoupling the housing (104), and the handpiece has a rotary clamping device (120) in which the rotary tool (210) can be attached.

An interproximal reduction tool and method preferably includes at least one polishing strip; at least one abrasive wheel; and a low speed and high torque dental electric motor. First, the area between two adjacent teeth is manually polished with the a plurality of polishing strips. The polishing strip is held between a forefinger and thumb and moved in a horizontal plane. Each abrasive wheel preferably includes an abrasive disc and a shaft. The abrasive disc includes a disc base and abrasive material. The abrasive material is adhered to opposing sides of the disc base. It is preferable to have an annular space between an outer edge of the disc base and an outer perimeter of the annular abrasive material. The low speed/high torque motor preferably utilizes an existing dental motor and modifies the dental motor to have a preferable gear reduction of at least 16:1.

The present invention relates to a cutting device (1) for surgical or dental use, comprising a motor (10) connected to a handpiece (4) provided with a transmission module (2) for a cutting tool (3), the transmission module (2) comprising: a motor coupling part arranged to be set in rotation by the said motor (10); a kinematic chain transforming the rotary movement of the motor (10) into a first linear reciprocating movement (M1) of a blade holder (27) via a rotary transmission shaft (22) provided with an eccentric (23), the transmission module (2) being characterized in that it further comprises a counter-mass (5) arranged so as to move according to a second linear reciprocating movement (M2) synchronized with the first linear reciprocating movement (M1) of the blade holder (27), and in the opposite direction to the latter.
