摘要： Ceramic implants, such as spinal implants, may comprise a dense shell and a porous core. In some implementations, methods for manufacturing the implants may comprise one or more stages at which the core material abuts the shell so as to form a mechanical attachment therewith while both the core and the shell are in a green state. The core and the shell may be fired together, and the resultant implant may, in some embodiments, comprise a unitary piece of ceramic material. Some embodiments may comprise silicon nitride ceramic materials.
摘要翻译： 诸如脊椎植入物的陶瓷植入物可以包括致密的壳和多孔的核。 在一些实施方案中，用于制造植入物的方法可以包括一个或多个阶段，在该阶段，芯材料抵靠壳体，以便在芯部和壳体都处于绿色状态的同时形成机械附件。 芯和壳可以一起烧制，并且在一些实施例中，所得到的植入物可以包括整体的陶瓷材料。 一些实施例可以包括氮化硅陶瓷材料。

摘要： Ceramic orthopedic implants may have one or more dense inner layers and one or more porous outer layers. Methods for manufacturing the implants may include one or more stages during which the dense inner layer(s) are partially compressed. At least one porous outer layer may include coating particles that are present at a surface of one or more inner layer(s) while pressure is applied to attach the coating particles to the inner layer(s) and to further compress one or more of the inner layer(s). Various layers may be formed until an implant, or other device, is formed having the desired density gradient and/or other properties, as disclosed herein.
