METHOD OF FINISHING TOOTH PROSTHESES OF CORROSION-RESISTANT STEEL

摘要

FIELD: orthopedic stomatology. SUBSTANCE: finishing is performed in several steps: preliminary treatment by abrasive composition based on organosilicon hermetic is followed by two-step polishing. In the first polishing step, diamond past with particle size 0.5-1 mcm is used and, in the second step, used past is based on superfine aluminum oxide powder and consists of spherical particles 0.6-0.9 mcm in size. EFFECT: increased corrosion resistance of prostheses and reduced content of harmful impurities in saliva. 3 dwg, 1 tbl øøø1
