[A new electrophoretic method for coating metalceramic elements with opaque].
A new, electrophoretical method of coating dental alloys (Au or Ni-Cr) with opaque is described for the first time. The comparison of this method with the known wet brush technique shows that bubbles or voids might occur at the interface between metal and opaque when applying the first ceramic layer manually whereas the electrophoretical one generates a thin and dense layer of porcelain being free of voids within the adherence zone. Those bubbles are considered to be inherent with the brush technique. The author suggests to galvanize dental alloys particularly noble metals in order to suppress any anodic reactions. General advantage for the bond due to galvanization are expected no matter how the opaque was applied.
