JPH09140726A - Tip for cleaning tooth surface - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a tip for cleaning the tooth surface capable of polishing the tooth surface without damaging the tooth surface. SOLUTION: A known ultrasonic vibrator transducer is built in a handpiece 10 and the tip 1 is so formed as to be connected preferably by a screwing system onto a vibrating shaft of the ultrasonic vibrator transducer. At least the part of the tip 1 which comes into contact with the tooth surface is formed of a resin so that the tooth surface is not damaged even if the tip rubs the tooth surface by coming into contact therewith. The front end of the tip 1 is, therefore, formed of a resin member 2. The front end of the resin member or the part near the front end is brought into contact with the tooth surface and is ultrasonically vibrated by the ultrasonic vibrator transducer in the handpiece 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tooth surface cleaning chip, and more particularly to a chip for cleaning a tooth surface by contacting the tooth surface and rubbing the tooth surface.

[0002]

2. Description of the Related Art Heretofore, a scaler for removing dental plaque adhering to teeth has been known as an instrument for cleaning teeth. In this scaler, a chip is manually scraped off plaque attached to the tooth, or a tip is attached to the tip of a handpiece containing an ultrasonic transducer, and the tip is brought into contact with the tooth and It has been proposed to remove the plaque by vibrating it.

[0003]

Recently, there is a strong demand for the tooth surface to look clean (clean), but the purpose of the scaler is to remove the plaque adhering to the back side of the tooth. Yes, the scaler does not allow the tooth flank to be polished to clean it.

The present invention has been made in view of the above-mentioned circumstances, and has been made with the object of proposing a tooth surface cleaning tip capable of polishing a tooth surface without damaging the tooth surface. Is.

[0005]

In order to solve the above-mentioned problems, the present invention is detachably attached to a distal end of a handpiece containing an ultrasonic transducer and contacts the tooth surface to clean the tooth surface. The tooth surface cleaning tip is characterized in that a contact portion with the tooth surface is made of resin.

Further, in order to achieve the above-mentioned object more effectively, the present invention is configured such that the side of the tip mounted on the handpiece is made of a metal member and the side contacting the tooth surface is made of a resin member. The metal member and the resin member are detachable by a screw mechanism, and the metal member and the resin member are integrally molded at the time of molding, The metal member is 0 to 1
Characterized by being bent in the range of 35 °,
Characterized in that the entire chip is integrally molded of resin, the chip has a metal member inside,
The one characterized in that the outside is integrally formed of resin, and further that the tip has a water passage hole inside, and water is jetted to the tooth surface through the water passage hole. It is characterized by that.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 to FIG. 3 are schematic views of the essential parts for explaining an embodiment of the present invention.
Is a tip for cleaning tooth surfaces according to the present invention, 10 is the tip 1
A handpiece for removably mounting the ultrasonic transducer, the well-known ultrasonic transducer is incorporated in the handpiece 10 like the ultrasonic scaler, and the chip 1 is a vibration of the ultrasonic transducer. The shaft is preferably adapted to be screwed on.

Thus, at least the portion of the chip 1 according to the present invention that comes into contact with the tooth surface is made of resin so that the tooth surface will not be damaged even if it is rubbed against the tooth surface. 1 to 3, reference numeral 2 is formed of a resin member, and the tip end portion or the vicinity of the tip end portion of the resin member 2 is brought into contact with the tooth surface and ultrasonically vibrated by an ultrasonic transducer in the handpiece 10. It is like this.

Thus, in the embodiment shown in FIG.
The chip 1 is composed of a resin member 2 and a metal member 3, and the resin member 2 and the metal member 3 are detachably connected by a screw connection 4. Alternatively, the metal member and the resin member are integrally molded, so that the resin member 2 is securely attached to the metal member 3 so that the resin member 2 does not fall off during the work. . Further, the metal portion 3 and the resin portion 2 are provided with water passage holes 2a, 3a for flowing washing water.
By spraying water toward the tooth surface through a and 3a, the tooth surface can be cleaned more effectively, and the scraped powder is immediately washed off, and the tooth surface is damaged by these powders. I am trying not to. Chip 1
Of course, it may be a straight line, but as shown in the figure, it is easier to use if it is bent to some extent, so in practice, it is bent in the range of θ = 0 to 135 °.

FIG. 2 is a view for explaining another embodiment of the chip according to the present invention. In this embodiment, the metal member 3 is inside and the metal member 3 is integrally molded and covered with the resin member 2. It is a thing. In this way, the screw coupling portion 4 in the embodiment shown in FIG. 1 can be eliminated, and there is no concern that the resin member 2 will fall off the metal member 3.

FIG. 3 is a view for explaining still another embodiment of the chip according to the present invention. In this embodiment, the chip 1 is formed only by the resin member 2. Can be made much easier and a cheaper chip can be provided.

[0012]

As is apparent from the above description, according to the present invention, it is possible to inexpensively provide a tooth surface cleaning tip that can effectively polish the tooth surface without damaging the tooth surface. it can.
