title: [Influence of finishing techniques on the surface roughness of metallic components of prosthetic restorations].
abstract: The paper proposes to examine the influence of mechanical and electrolytic finishing techniques on metal surface roughness.
  
  
  METHODS
  Six non-noble dental alloys and three versions of finishing have been taken into consideration: mechanical polishing with rubber polisher, mechanical polishing with cotton polisher and abrasive paste and electrolytic polishing. Examinations on roughness have made reference to Rz, Ra and Rq.
  
  
  RESULTS
  The experimental results obtained have shown that mechanical polishing with rubber polisher is recommended for Co-Cr-Mo alloys, while mechanical polishing with cotton polisher and abrasive paste or electrolytic polishing are suited for Ni-Cr alloys.
  
  
  CONCLUSIONS
  Analysis of values obtained led to formulation of recommendations concerning the best polishing method for each non-noble alloy considered.
