Disclosed are a dental treatment data matching method and a digital dentistry device therefor. In the dental treatment data matching method according to an embodiment, feature points of individual teeth are extracted when carrying out matching between pieces of dental treatment data required for dental treatment plan validation, matching reference points are extracted from among the extracted feature points, and matching between pieces of data is carried out by using the extracted matching reference points, and thus, the accuracy may be increased by improving matching errors, and convenience of use may be increased by minimizing user intervention.

The present invention relates to an ampoule for implant storage and, more particularly, to an ampoule for implant storage with a function of bidirectional humidity maintenance that can suppress excessive moisture supply from a hydrophilic carrier in the ampoule to the implant surface, thereby solving the problem of the coating solution coming off due to external impacts. The ampoule for implant storage with a function of bidirectional humidity maintenance according to the present invention includes an ampoule container and a separator, which is accommodated in the ampoule container. The separator separates the inside of the ampoule container into a first space and a second space and has at least one through hole that allows moisture to move between the first and second spaces. An implant is accommodated in the first space and has a hydrophilic coating layer formed on at least a portion of the surface thereof. A hydrophilic carrier is accommodated in the second space and supplies moisture to the hydrophilic coating layer formed on the implant surface. Since the hydrophilic coating layer on the implant surface and the hydrophilic carrier contain one or more organic zwitterionic buffering materials having a sulfonic acid group, a moisture balance is maintained therebetween.

An embodiment of the present disclosure provides an oral scanner calibration device including: a casing into which an oral scanner body is inserted; a reflector part disposed on a central axis of the oral scanner body and configured to reflect light irradiated from an optical device of the oral scanner body; a pattern plate part configured to face the optical device through the reflector part; a rotating part mechanically fastened to the reflector part and the pattern plate part; and a driving part configured to provide a driving force to the rotating part, wherein, in conjunction with rotation of the rotating part, the reflector part linearly moves relative to the oral scanner body, and the pattern plate part rotates about an optical axis of the light reflected by the reflector part.

Provided in one embodiment of the present invention is an implant surgery guide device comprising: a support for covering the buccal surface, lingual surface and occlusal surface of a tooth; a surgical part, which corresponds to an implant surgical position, has a through hole coming in contact with the outer peripheral surface of a drill head of a drill device, and has an opening formed at one side thereof; and a guide part, which is formed in the opening of the surgical part, and has an oblique slit through which a boring means of the drill device can obliquely pass.

Disclosed are a method, a device, and a recording medium, according to one embodiment, the method comprising the steps of: acquiring scan data for an oral cavity; acquiring undercut data including data on undercut location and undercut depth determined on the basis of an insertion path of an insert body corresponding to the oral cavity; acquiring an oral modeling image including an undercut area divided into a plurality of areas on the basis of the scan data and the undercut data; acquiring an updated oral modeling image on the basis of the undercut depth for an area adjacent to a target area according to a user input applied to the target area including one of the plurality of areas; and displaying the updated oral modeling image.

One aspect of the present invention provides a photocurable resin composition for a surgical guide, which comprises 20 to 50 parts by weight of (meth)acrylate-based urethane copolymer; 40 to 70 parts by weight of a first (meth)acrylate-based monomer; 4 to 9 parts by weight of a second (meth)acrylate-based monomer; 1 to 4 parts by weight of a photoinitiator; and 0.005 to 1 parts by weight of a UV absorber, a surgical guide manufactured therefrom, and a method for manufacturing the same.

A method performed by a computing system according to one embodiment of the present disclosure, comprises the steps of: determining a masking area of a current layer on the basis of a non-overlapping area between the current layer and at least one previous layer from among a plurality of layers; and updating an image of the current layer in accordance with a user input for setting a light exposure amount with respect to the masking area of the current layer, wherein the plurality of layers are designed to sequentially cure a photocurable material in each layer unit for 3D printing.

Disclosed is a method for providing a dental abutment by using data about a customized abutment, comprising the steps of: receiving oral data about a patient; and acquiring a standardized abutment from a standardized abutment group generated from the customized abutment in correspondence with the inputted oral data about the patient.

The present invention provides a foot controller for a dental unit chair capable of easily and conveniently controlling the amount of air supplied to a treatment tool provided in the dental unit chair. The present invention provides a foot controller for a dental unit chair, including: an air valve configured to control a flow rate of air supplied to the treatment tool; a cam block configured to be installed under a rod provided in the air valve and having an inclined surface; a pedal unit configured to be disposed at a location spaced apart from the cam block by a predetermined distance and rotatable left and right by an external force and movable up and down; and a connection part configured to connect the cam block and the pedal unit so that the cam block moves in conjunction with movement of the pedal unit.
