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.
