Disclosed is a manufacturing method of a customized tongue-side invisible aligner, and belongs to the technical field of orthodontic treatment. The manufacturing method comprises steps of: performing three-dimensional scanning of a patient's teeth via
laser to obtain image information; performing simulative alignment of teeth on a computer to obtain an ideal tooth alignment effect, and determining a tooth model scheme; printing the tooth model scheme of simulative alignment by using a 3D printer; designing three-dimensional models of an aligning bracket, a bracket baseplate, and an aligning steel wire, which are special for each tooth, by
computer aided design and
manufacturing technology. The manufacturing method is characterized by further comprising:
carving the aligning bracket by adopting stainless steel via a numerically-controlled
machine tool; selecting a stainless steel board, and
carving a shape, identical to the teeth, at the lower surface of the stainless steel board via the numerically-controlled
machine tool; and selecting a stainless steel mesh and
welding the stainless steel mesh to the lower surface of the stainless steel board. According to the manufacturing method, an integrate bracket is manufactured by directly adopting three-dimensional image information, so that the bracket is high in precision and good in comfort during an orthodontic treatment process.
