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.
作为单冠和桥基牙的基础，单个铸造结构与制造的根桩相结合具有无可争议的优势。在铸造银钯合金时，根桩可能会改变其材料的特性。研究了sipal与由纯钛制成的圆柱形销（EMO Ti110）以及由植入钢制成的带粘结头的根桩（URX2CrNiMoN18.12(0]）的铸造反应。通过金相（研磨）试样的光镜和电子束显微镜照片可以证明sipal与植入钢和钛制销之间无间隙铸造。铸造质量主要通过包埋材料的选择、预热温度的升高和预热时间来确定。
