As a base for single crowns and bridge anchors the individual casted construction combined with the manufactured root post offers undisputed advantages. At casting silver-palladium alloys, the root posts possibly may change the characteristic properties of their material. The casting reactions of sipal with cylindrical pins made of pure titanium (EMO Ti110) and root posts with adhesion head made of implant steel (URX2CrNiMoN18.12(0] was investigated. Interstice-free castings of sipal to pin from implant steel and titanium can be demonstrated by means of pictures of metallographic (grinding) specimens investigated by light- and electron-beam microscopy. The casting quality is identified mainly by selection of the embedding mass, the rise of the preheating temperature and period of preheating.
