Description

A fusion type apex length measuring device in which an electronic apical foramen recognizer and an endodontic file digital measuring device are fused

The present invention relates to a fusion type apex locator measuring device in which an electronic apical foramen recognizer and an apical file digital measuring device are fused, and more particularly, an electronic apical foramen recognizer for recognizing an apical foramen and a file obtained by the electronic apical foramen recognizer. A file length measurement function that measures the length and a file length setting function that sets the file length of subsequent files for root canal enlargement based on the measured apex length can be combined to perform various digital functions in a complex way. It relates to a fusion-type apex locator measuring device.

In general, there is an organization called dental pulp in a tooth, and the dental pulp is composed of nerves, blood vessels, etc., and functions to supply nutrients, moisture, etc. to the tooth and feel sensation.

When the pulp is in an inflammatory state due to infection due to tooth decay or the like, it is called pulpitis, and the treatment of pulpitis is called root canal treatment (neurotherapy).

Endodontic treatment is a procedure that completely removes the infected pulp tissue using a special instrument, sterilizes the root canal to make it sterile, and then fills the space occupied by the dental pulp using biocompatible materials.

Here, in order to treat the root canal, it is necessary to measure the length of the root canal first. For the measurement of the length of the root canal, an electronic apical foramen recognition device for recognizing the apical foramen is used.

The electronic apical foramen recognition device is a device that recognizes that the device reaches the apical tissue using the electrical resistance of the human body, and the earth terminal connecting the person's lips and the connection terminal connecting the apical periodontal ligament are each in place It is focused on the fact that the moment when a cutting tool such as a file enters the root canal when a current of about 40 ㎂ is inserted and the resistance reaches about 6 kΩ is the apical end.

Therefore, the electronic apical foramen recognition device triggers an alarm when the end of the file reaches the apical end, and regards the insertion depth as the apical length.

When the position of the apical end is known through the electronic apical foramen recognition device, the file stopper is placed on the upper surface of the tooth, the file is pulled out, and the length from the end of the file to the stopper is measured by applying it to an analog endodontic file measuring device to measure the length of the apical canal.

In addition, when the root canal length is measured, the root canal enlargement procedure continues and the enlargement file for root canal enlargement must be inserted into the root canal. The length of the apex measured by the device should also be displayed in the subsequent file.

That is, when the operator measures the apical length through the electronic apical foramen recognition device and the endodontic file measuring device, the stopper of the file is moved to the measurement point to display the apical length, and when the apical length is displayed on the file through the stopper, the subsequent file It is necessary to move the stopper to the same position, mark the length of the root canal, and then perform a process of inserting it into the root canal of the tooth to be treated.

As such, the adjustment of the stopper position of the file depends only on the operator's eyesight and manual work, so there is a limit to the accuracy of the apex length alignment. There was also the problem of touching a nerve and causing pain.

Therefore, the electronic apical foramen recognizer for recognizing the apical foramen, the file length measuring function for measuring the length of the file obtained by the electronic foramen hole recognizer, and the file for setting the length of subsequent files for root canal enlargement based on the measured apex length. A convergence-type apical locator that combines an endodontic file digital measuring instrument with a length setting function to perform various digital functions in a complex way to increase operator convenience and efficiency. development is required.
