A system for revising a set of teeth including a bracket for revising a set of teeth and a bracket positioning jig is provided. The bracket positioning jig includes a cap at the lower portion of which a groove contacting tooth is formed, and which has a throughhole to lengthy direction on the upper portion of a cap body, and a connector one side of which has a fixed protrusion which is detachably inserted into and fixed to the throughhole of the cap, and the other side of which is bent toward the lower end of the body and has a coupler which is combined on a slot of an orthodontics treatment bracket for revising a set of teeth. An individual prescription value which is the most appropriate for an individual patient is given to the bracket positioning jig on a computer program to thus manufacture a desired jig, so that a non-prescription bracket as well as a bracket having a given prescription value can be used.
