The present invention provides a kind of selective laser sintering of the individual lingual orthodontic brackets indirect manufacturing method, which comprises the following steps: measuring the tooth shape data structure parameters of the tooth; a tooth used to reverse engineering method of 3D CAD model and stored in the computer; according to the requirements, the shape characteristics of orthodontic brackets and dental materials the structure design of each model, the design of the structure model of the bracket bracket; the bracket comprises a bottom contact design with the tooth surface, and the position determining groove bracket according to each bracket ideal; according to the structure model and mold bracket casting requirements, using selective laser sintering technology, using the method of layered manufacturing mold manufacturing bracket required to produce metal brackets; using the method of investment casting. The method can realize customized manufacture with high precision according to individual differences. The bracket can be applied to the surface of the tooth, thereby saving working procedure, time and cost, and having wide application range and diversified production materials.
