Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tip device for a root canal treatment file using a dental ultrasonic vibration device.

Conventionally, root canal treatment in dentistry has been performed by manipulating the tip with finger movements of the doctor. In this case, a rectangular shape is provided in the file portion of the tip in a spiral shape, and when the tip is inserted into the root canal, rotational motion is applied, and the root canal wall is enlarged and cut by a pulling operation. This treatment requires a high degree of skill and a long treatment time (see Fig. 1).In this case, the production cost of the bladed file is prohibitive and the cutting damage is significant.

In recent years, ultrasonic devices have been applied to dental treatment, but they have not yet been used for root canal treatment. There are only a few experiments in which the above-mentioned hand file was connected to an ultrasonic device. (Refer to Figure 2) Using the ultrasonic vibration device for testing as shown in Figure 2. (2) The tip device for the root canal treatment file is a hand-type file attached to the ultrasonic vibration device, which is necessary for root canal treatment. Although it has a slightly curved shape, the three parts, the file part, the file holding part, and the connecting part, are made of different materials, and the connecting part has poor bonding, so it is difficult to use the vibrator of the ultrasonic vibrator. It is not tuned to the frequency and causes vibrational distortion in the file, making treatment difficult and even causing file breakage. Furthermore, the file holding device is too large, making it inconvenient to use. Furthermore, the blade is not suitable for ultrasonic vibration and is not suitable for cutting the root canal wall, requiring unnecessary techniques and being extremely inefficient.

A device based on the present invention has been created to eliminate the above-mentioned drawbacks.

The present invention includes a conventional chip device consisting of a file part, a file holding part, and a connecting part, which are made of the same metal as one unit, and the file part is shaped like a needle with a smooth surface without providing a blade part, and is used for grinding the root canal wall. A chip device having a curvature suitable for polishing, which is connected to an ultrasonic vibration device (6) The present invention will be explained with reference to the drawings based on one embodiment. FIG. 3 shows a file tip device for root canal treatment using an ultrasonic vibrating device according to the present invention. In the present invention, the file holding part 8 and the file part 7 are integrally made of a certain metal such as stainless steel, and the file tip is needle-shaped with a smooth surface. The smooth needle-like tip of the file works effectively and appropriately to enlarge and polish the root canal through ultrasonic vibration, and the finished root canal wall is highly smooth.
The operating technique is simple and treatment time is shortened. Smooth files prevent excessive grinding of the root canal and generate less heat, making them effective for treatment. Furthermore, the smooth file tip is less expensive to manufacture and ensures uniformity, resulting in less wear and tear. By integrating the chip, the entire mass can be accurately matched to the ultrasonic frequency, and there is no vibration distortion caused by the use of different metal materials or poor bonding, making it possible to prevent breakage and treatment. It can also prevent accidents inside. Chip 1, (
4) Physicalization reduces the size and weight, which is convenient for treatment.

In the present invention, it is also possible to create six pieces including a file with a smooth needle-like tip, a file holding part, and a connecting part.

Furthermore, based on the present invention, it is also possible to process the tip of the file with diamond powder, in which case the therapeutic effect can be further improved.
