Digital measurement device and measurement method

Abstract

A digital measurement device according to the present invention comprises: a cradling unit on which a measurement target is placed; and a measurement unit for measuring the length of the measurement target and providing a reference value for adjusting the length of a new measurement target by means of the measurement value of the measured measurement target. The measurement unit measures the length of the measurement target by using at least one of the following types: a movement type in which same interferes with the measurement target that enters the cradling unit, and accordingly calculates the distance of movement; an emission type in which same emits a measurement signal toward the measurement target and accordingly calculates the length of the measurement target on the basis of the sensed measurement signal information; and a scanning type in which same scans the measurement target. The above configuration ensures that, through a simple structure, the accuracy of measuring the length of the measurement target can be improved.

Description

technical field [0001] The present invention relates to a digital measurement device and a measurement method, and more particularly, to a digital measurement device and a measurement method capable of precise measurement of a measurement object such as a dental endodontic file. Background technique [0002] Typically, dental endodontic files are used for dental treatments such as determination of root crown length, size (nervation) removal and root crown formation. Among them, the formation of the root cap is a process of cleanly removing and enlarging the nerve remaining inside the nerve tube of the tooth and the infected nerve tube wall. [0003] On the other hand, in order to treat the root cap, it is necessary to first measure the length of the root cap. Since the nerve length of each patient's tooth is different, this type of root crown treatment requires the use of an endodontic file that matches the patient's nerve length. [0004] Usually, a stopper is provided on...

[0005] On the other hand, if the position of the stopper of the endodontic file is adjusted manually by the treating staff, it is difficult to read the fine scale, and the accuracy of length measurement is limited.

Not only that, but the position of the stopper may not be changed due to the error of the treatment personnel. Therefore, repeated measurement of the length will lead to a longer operation time, and at the same time, the reliability of the treatment will be reduced.
