Abstract

There is provided a substantially disposable dental tip incorporated in an ultrasonic scaler and a dental working distal end piece used for the dental tip.

The dental tip in accordance with the present invention includes a transmission medium whose proximal end portion is connected to an ultrasonic vibration source to transmit ultrasonic vibrations generated from the ultrasonic vibration source and the dental working distal end piece of the present invention which is mounted on a distal tip end of the transmission medium and consists of a tip end member having a shape suitable for dental treatment etc. and a connecting portion connected integrally to a proximal end portion of the tip end member.

Claims

1. A dental tip comprising:

a transmission medium having a distal tip end and a proximal end adjusted to be connected to an ultrasonic vibration source, for transmitting ultrasonic vibrations generated from said ultrasonic vibration source; and

a dental working tip end piece adapted to be detachably mounted on the distal tip end of said transmission medium;

wherein said transmission medium includes a protrusion formed on the peripheral surface of the distal tip end, and diamond particles embedded in at least a part of said peripheral surface of the distal tip end;

said dental working tip end piece consists of a plastic connecting portion and a tip end portion of a shape suitable for dental treatment, said plastic connecting portion having a bottomed hole extending in the longitudinal direction of said dental working tip end piece and adapted to having the distal tip end of said transmission medium fitted in, and a hole formed in the inner wall of said plastic connecting portion for engaging said protrusion therein.

2. The dental tip according to claim 1, wherein said connecting portion of said dental working tip end piece has a through hole extending in the radial direction of said dental working tip end piece and adapted to have a said distal tip end of said transmission medium fitted therein.

3. A dental tip comprising:

a transmission medium having a distal tip end and a proximal end adjusted to be connected to an ultrasonic vibration source, for transmitting ultrasonic vibrations generated from said ultrasonic vibration source; and

a dental working tip end piece adapted to be detachably mounted on the distal tip end of said transmission medium;

wherein said transmission medium includes a recess formed on the peripheral surface of the distal tip end, and diamond particles embedded in at least a part of said peripheral surface of the distal tip end;

said dental working tip end piece consists of a plastic connecting portion and a tip end portion of a shape suitable for dental treatment, said plastic connecting portion having a bottomed hole extending in the longitudinal direction of said dental working tip end piece and adapted to having the distal tip end of said transmission medium fitted in, and a protrusion formed in the inner wall of said plastic connecting portion for engaging said recess therein.

4. The dental tip according to claim 3, wherein said connecting portion of said dental working tip end piece has a through hole extending in the radial direction of said dental working tip end piece and adapted to have a said distal tip end of said transmission medium fitted therein.
