To improve convenience and precision in manufacturing an orthodontic apparatus, the present invention provides a method of manufacturing digital brackets for orthodontics using a digital library, including a first operation of loading an oral scan image obtained corresponding to an internal profile of an oral cavity of a subject and extracting one virtual orthodontic template corresponding to each of tooth images that are virtually adjusted according to a preset consecutive tooth arrangement structure from a digital library, a second operation of aligning and disposing each of virtual brackets and a virtual wire of the extracted virtual orthodontic template corresponding to the consecutive tooth arrangement structure of each of the tooth images that are virtually adjusted, and a third operation of designing each of digital brackets configured to include a jig portion assembled with a top of each of the virtual brackets to surround a top of each of the tooth images and a grip protrusion portion configured to protrude from a top end of the jig portion while being integrated therewith, and three-dimensionally printing each of the digital brackets based on design data.
