Customized tongue side orthodontic bracket and manufacturing method thereof

Abstract

The invention discloses a customized tongue side orthodontic bracket and a manufacturing method thereof. The tongue side orthodontic bracket comprises a bracket body commonly defined by a tooth direction surface and tongue direction surface, wherein a sunken part is formed in the middle region of the tongue direction surface of the bracket body, an upper wing and a lower wing are arranged in the sunken part and a groove is formed in the sunken part; a circular-arc-shaped outline is maintained among the tongue direction surface of the bracket body and the outer surfaces of the upper wing and the lower wing. The manufacturing method of the bracket comprises the main steps of establishing a virtual bracket body in a computer, setting a central line of the groove, acquiring a tooth arrangement model with ideal tooth rows, determining a virtual forming position of the groove, matching the central line of the groove with the virtual forming position of the groove, rotating the bracket body around the central line so as to regulate the position of the bracket body and the thickness of the bracket body, cutting the groove along the central line to obtain the bracket body with the groove, and finally generating the real bracket by virtue of 3D printing. The tongue direction surface of the whole bracket body is machined into a circular arc shape, so that the stimulation to a tongue of a patient can be greatly relieved, and the comfort level of the patient is increased.

Description

technical field [0001] The invention relates to the technical field of oral orthodontic appliances, in particular to a lingual orthodontic bracket and a manufacturing method thereof.
