    摘要： Joint prosthesis comprises a part with a metal core that is coated with a glass ceramic in areas in rolling and/or sliding contact with another part of the joint. The glass ceramic has one of three defined oxide compositions, e.g. (wt.%): silicon (45-50), aluminum (15-20), zirconium (8-12), potassium (8), sodium (7.5), calcium (2.5), titanium (1.5) and manganese(IV), iron(III) and/or cobalt(III) (up to 12.5). Joint prosthesis comprises a part with a metal core that is coated with a glass ceramic in areas in rolling and/or sliding contact with another part of the joint. The glass ceramic has one of the following oxide compositions (wt.%): (A) silicon (45-50), aluminum (15-20), zirconium (8-12), potassium (8), sodium (7.5), calcium (2.5), titanium (1.5) and manganese(IV), iron(III) and/or cobalt(III) (up to 12.5); (B) silicon (35-55), aluminum (15-25), titanium (10-14), sodium (7.5), potassium (7), zirconium (1-5), calcium (0.5) and manganese(IV), iron(III), cobalt(III) and/or copper(II) (up to 24); or (C) silicon (50-60), aluminum (5-10), zirconium (5-10), sodium (8), calcium (6), titanium (3-5), potassium (2), antimony(V) (0.5) and manganese(IV), iron(III), cobalt(III), copper(II) and/or cerium(IV) (up to 20.5).

    摘要： PROBLEM TO BE SOLVED: To provide an implant body, a method of manufacturing the same, and a dental implant having good biocompatibility and a high degree of bone attachment.
    SOLUTION: The implant body 2 to be stabilized in contact with a bone comprises a base material 2a formed of zirconia, and a surface layer 2b that is softer than the base material 2a and formed on the surface of the base material 2a. More specifically, the implant body not only is superior in mechanical strength because of the base material 2a formed of zirconia, but also functions as a buffer layer wherein the soft and flexible surface layer 2b eases the difference in the degree of hardness between the bone and the base material 2a. The soft surface also improves the adhesion of the implant body 2a to the bone.

    摘要翻译： 要解决的问题：提供一种植入体，其制造方法以及具有良好的生物相容性和高附着度的牙科植入物。 解决方案：待稳定的与骨接触的植入体2包括由氧化锆形成的基材2a和比基材2a更软并形成在基材2a的表面上的表面层2b。 更具体地，植入体不仅由于氧化锆形成的基材2a而具有优异的机械强度，而且还起到缓冲层的作用，其中软和柔性表面层2b减轻了骨与骨骼之间的硬度差异 基材2a。 柔软的表面也改善了植入体2a与骨骼的粘合性。 版权所有（C）2010，JPO＆INPIT
