Abstract

An endodontic file holder includes a wearing member worn on a part of the body; a holder body mounted on the outer side of the wearing member, having an inner side in which an accommodating space for accommodating a sponge is formed, and having openings through which the sponge accommodated in the accommodating space is exposed; a sponge inserted inside of the accommodating space formed in the holder body, wherein an endodontic file is inserted into the sponge; and a length measuring means provided in the holder body and configured to measure the length of an endodontic file, wherein at least one medicine receiving groove for accommodating a medicine for dental treatment to be applied to an endodontic file is formed on the upper surface of the holder body.

Abstract

Disclosed is a digital measurement apparatus including a holding unit on which a measurement object to be measured is placed; and a measurement unit for measuring the measurement object by comparing an image of the measurement object placed on the holding unit with a preset reference value, and providing a reference for adjusting the length of a new measurement object based on a measured value of the measurement object. With this configuration, regardless of photographing conditions, by performing calibration using a set reference value, the accuracy of a measured value may be improved.

Abstract

The present disclosure relates to a method of manufacturing a needle for root canal treatment devices having improved ductility. The method of the present disclosure includes a step of manufacturing a hollow needle body in a desired shape using an alloy or a single metal, a step of filling the hollow of the needle body with a packing member, a step of heat-treating the needle body at a predetermined temperature under an inert gas atmosphere after the needle body is placed in a vacuum chamber, and a step of cooling and hardening the needle body.
