1. THE METHOD OF FORMING A GENERALLY BARREL-SHAPED ORTHODONTIC BAND WHICH TERMINATES IN OPPOSED INCISAL AND GINGIVAL EDGES AND PROGRESSIVELY DIMINISHES IN DIAMETER FROM ITS AXIALLY MEDIAL PLANE TOWARD SAID EDGES TO DEFINE A RADIALLY ENLARGED GIRTH PORTION INTERMEDIATE SAID EDGES, SAID METHOD COMPRISING THE STEPS OF: PROVIDING A GENERALLY CYLINDRICAL, RELATIVELY THIN-WALLED SLEEVE HAVING A DIAMETER APPROXIMATELY EQUAL TO THE DESIRED GIRTH DIAMETER OF THE FINISHED ORTHODONTIC BAND, AND BARRELING SAID SLEEVE BY DEFORMING THE WALL OF SAID SLEEVE RADIALLY INWARD IN THE REGIONS THEREOF BETWEEN THE AXIALLY MEDIAL PLANE AND THE ENDS OF SAID SLEEVE TO CONSTRICT SAID REGIONS TO PROGRESSIVELY DIMINISHING DIAMETER TOWARD SAID ENDS.
