Orthodontic digital bracket for using digital library and method of manufacturing the same

1. A method of manufacturing an orthodontic digital bracket using a digital library, comprising:

loading an oral scan image obtained corresponding to an internal profile of an oral cavity of a subject onto a simulation apparatus for three-dimensional image processing;

virtually adjusting each of tooth images in the oral scan image according to a preset consecutive tooth arrangement structure, using the simulation apparatus, including

separating each of the tooth images from a gum image in the oral scan image,

setting an alignment reference portion at each of the tooth images, each alignment reference portion including a first reference line configured to connect a central portion with both sides of each of the tooth images and guide a lateral movement of thereof, and a second reference line configured to guide a longitudinal movement corresponding to an implantation angle of each of the tooth images, and

virtually adjusting each of the tooth images by three-dimensionally processing the alignment reference portion, including virtually rotating and moving each of the tooth images such that first reference lines of the tooth images virtually adjusted form a consecutive tooth arrangement structure which conforms to the preset consecutive tooth arrangement structure;

extracting a virtual orthodontic template, which has virtual brackets and a virtual wire connecting the virtual brackets in series, from the digital library saved at a storage medium;

virtually aligning and disposing each of the virtual brackets to correspond to the consecutive tooth arrangement structure of the tooth images that are virtually adjusted, using the simulation apparatus;

designing each of digital brackets including

i) a jig portion assembled with a top of each of the virtual brackets and configured to surround a top of each of the tooth images virtually adjusted, and

ii) a grip protrusion portion protruding from a top end of the jig portion while being integrated therewith, using the simulation apparatus; and

three-dimensionally printing each of the digital brackets based on design data created by the designing each of the digital brackets.

2. The method of claim 1 , wherein the designing includes:

forming a segment edge partially incised along a boundary portion between the jig portion and the top of each of the virtual brackets; and

forming a marking portion on which type and position information of each of teeth is displayed at an end of the grip protrusion portion.

3. The method of claim 1 , wherein the digital library comprises digital external shape information of a plurality of virtual orthodontic templates that includes a dental arch profile, a type of a tooth, and an arrangement interval and angle as selection items.

4. The method of claim 1 , further comprising:

designing a retainer apparatus comprising a first cover groove portion assembled with an external profile of each of the tooth images to fix a state in which the digital brackets are installed at each teeth and a second cover groove portion assembled with external profiles of the virtual brackets and the virtual wire.
