Summary:This invention relates to a production method for a hard invisible brace set for stepped correction of a tooth row, wherein the hard invisible brace set includes a plurality of relay braces. The production method includes: firstly, acquiring an original tooth row image file of a tooth jaw of a patient; then, arranging, by a dental technician, a final tooth row image file on tooth arrangement software; next, defining displacements and rotation angles, required in each step, of teeth, and performing calculation by virtue of the arrangement software to obtain a plurality of stepped tooth row image files; and then, defining the surface thickness of each stepped tooth row image file by virtue of special software to obtain a shell-like brace image file of each relay, converting the shell-like brace image file into a numerical control instruction to control a multi-axis carving machine to carve hard invisible braces on a hard module made of a high-molecular polymer, and enabling the patient to wear the hard invisibl
