Abstract: Implant bore insert has an outer surface that is, at least in part, substantially cylindrically aligned. The insert may be blind, thus forming a cup, or it may be open ended. The insert can be provided with a predetermined outer circumferential surface that provides for a suitable interference fit with a corresponding bore hole of an implant component part. When inserted into the bore hole, the insert preferably seats itself on a blind end of the bore hole. Examples of implants employed with the insert can include ceramic ball joint heads and teeth.

Abstract: Ceramic bodies can be made by providing an initial green body of ceramic; and machining the initial green body to provide a machined green ceramic body. Embedding the initial green body in an embedding mass can be avoided. The initial green body can be bisqued, infiltrated an adjuvant such as machining wax, removing the infiltrated body, and machining it. Highly detailed ceramic products can be generated. The machined green ceramic body may be fired and/or further processed to provide a more finished ceramic body. Examples include a femoral component for a posterior stabilized knee implant, a component body for an artificial rotation device containing knee implant prosthesis a dental implant or bridge, an ice skating blade, and so forth. Zirconia ceramics are advantageously employed, for an example, Mg-TTZ.
