Abstract: The present invention discloses an individualized orthodontic appliance with axis correction functions, comprising No. 1-7 individualized lingual brackets connected in series by an archwire. Each individualized lingual bracket includes a base plate and a bracket body connected with the base plate. In the No. 1-7 individualized lingual brackets, the underside of the bracket body of at least two of the individualized lingual brackets is disposed with a crimpable hook with a through hole and the through holes are connected in series by an ortho-axial wire. In this invention, the underside of the bracket body is disposed with the crimpable hook with the through hole and the ortho-axial wire is used to pass through the through holes. In this way, the underside of the bracket body can produce the corresponding orthodontic force while the crown of tooth is moving during the orthodontic treatment. The positions of the teeth roots can also be gradually corrected.

Abstract: The present invention discloses a universal lingual bracket system, comprising No. 1-7 universal lingual brackets connected in series by an arch wire. The universal lingual bracket includes a base plate and a bracket body portion that are integrated as a whole. A mesh bottom is arranged on the base plate and the mesh bottom is integrally molded with the base plate. The mesh bottom, the base plate and the bracket body portion are integrally molded. In addition, the mesh bottom is in the structure of an interlaced woven wire mesh, so that the universal lingual brackets have strong capability to be against the teeth surfaces and they are unlikely to come off. Even if they come off, they will not damage the mesh bottom. The mesh bottom can be used again once it is treated by sandblasting. The universal lingual bracket system provided by the invention has the advantages that it can be securely and easily installed and has high durability; therefore it is applicable to various universal lingual appliances.

Abstract: The present invention discloses a method for manufacturing a positioning tray and a bracket with a positioning hook for manufacturing the positioning tray. The method for manufacturing the positioning tray comprises the following steps: acquiring an original dental impression and an ideal dental impression; transforming the ideal dental impression to a three-dimensional digital model and drawing each bracket body; drawing a positioning hook on the bracket body; making a wax pattern of a bracket with the positioning hook by using a wax pattern machine; casting, with the wax pattern as a mould core, a blank of the bracket with the positioning hook which then receives surface treatment; after the surface treatment, assembling the bracket with the positioning hook to the original dental impression and performing film lamination to obtain a positioning tray, and finally removing the positioning hook to obtain the bracket matching the positioning tray.
