Purchasingthe best surgical quality materials. Skilled technicians are manufacturingthe shapes of each tip. Cutting and shaping each tip using CNC machinery.Proper bendingof each tip, from 1 o 6 times, to insure proper use qualities. Increasingthe strength of the instrumentswith the use of heat treating processes.Dental USA raisesthe level of heat treating to a 50-55 hardness rating,which increasesthe strength of the material and minimizeswear. Assembling the instrumentsproperly is of the utmost importance.If the tip is not inserted into the handle properly, it will not work correctly

and may break or fall out of the handle. Each instruments' tips are inserted by highlytrained and skilled technicians.As a final step to the process,we clean all of the instrumentsand do whatwe call a final "bladingn,or sharpening, to ensure the properworking edges are oneach and every instrumentto meet the specificationsof dental professionals.
