    • Dental devices such as crowns, bridges and implants are disclosed, such devices comprising a self-supporting structural layer, a ceramic outer layer attached to the structural layer, and a porcelain layer attached to the ceramic layer, the ceramic outer layer made of a nitride, oxide or oxynitride of titanium (Ti) or zirconium (Zr). The devices are biocompatible and can have thin layers that are exactingly tailored. In one embodiment, a gold layer is disposed between the ceramic outer layer and the porcelain layer. In one embodiment, the gold layer comprises a nanocomposite of gold and oxides, nitrides or oxynitrides of indium, tin or zinc. In one embodiment, the structural layer is made of a cobalt alloy having a coefficient of expansion that substantially matches that of the porcelain layer. Methods for making and using such devices are also disclosed, including vapor deposition of metal and/or ceramic layers.
    • 公开了诸如冠,桥和植入物的牙科装置,这种装置包括自支撑结构层,附着到结构层的陶瓷外层和附着到陶瓷层的瓷层,陶瓷外层由氮化物 ,钛(Ti)或锆(Zr)的氧化物或氧氮化物。 这些设备具有生物兼容性,可以精确定制薄层。 在一个实施例中,金层设置在陶瓷外层和瓷层之间。 在一个实施方案中,金层包括金和氧化物的纳米复合物,铟,锡或锌的氮化物或氮氧化物。 在一个实施例中,结构层由具有与瓷层基本一致的膨胀系数的钴合金制成。 还公开了制造和使用这些装置的方法,包括金属和/或陶瓷层的气相沉积。
