Orthodontic bracket
A method of manufacturing digital brackets for orthodontics, including: 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 virtually adjusted according to a preset consecutive tooth arrangement structure from a digital library, 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, and 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.
1. An orthodontic bracket, comprising:
a pad portion including a first side corresponding to a surface of a tooth of a subject, and a second side opposite to the first side and having a coupling groove portion configured to be coupled with a wire configured to provide tension to straighten a position of each of teeth;
a jig portion integrally formed with the pad portion as a single body and extended from a top of the pad portion to surround an external surface of a top end of the tooth to align a position of the pad portion, wherein the jig portion includes:
an assembling portion extended downward from a vertex of the jig portion and configured to surround the external surface of the top end of the tooth; and
an assembling groove portion formed on an inner surface of the assembling portion and configured to be assembled corresponding to a morsal surface shape;
a segment edge being partially incised along a boundary portion between the pad portion and the jig portion and configured to be broken by an external force using a principle of levers to split the pad portion and the jig portion along the segment edge; and
a grip protrusion portion integrally formed with and protruding upward from the vertex at a top center of the jig portion to be gripped, and having a preset height and a grip area so as to break the segment edge by the principle of levers when the external force is applied to the grip protrusion portion,
wherein the grip area includes a marking portion on which notification information on a type and a position of each of the teeth is formed, the notification information being symbolized and protruding from the grip area as raising letters.
