Abstract: A bone implant member for bone, joint, as well as dental prostheses, bone connecting elements such as bone screws and splints, which consists of a mechanically stable carrier material compatible (biocompatible) with bone tissue and of bioactive calcium phosphate ceramic, in particular tri- and tetracalcium phosphate, as well as a process for the production of such an implant member.

Abstract: A dental implant having a core member formed of a gingiva-compatible metal for mounting a dental superstructure in the shape of a tooth crown; a fastening element for dental bridges or the like, wherein the core member is connected with a tissue-compatible biostable polymer matrix which contains reabsorbable, bioreactive sintered calcium phosphate. The core member is constructed from a metal plate flat in cross-section and conformed with the implant shape and which is provided with apertures, wherein the polymer matrix is a covering encompassing the metal plate on all sides thereof and is constituted of a biostable polymer material and reabsorbable finely-divided, sintered calcium phosphate, and in which the apertures are filled with reabsorbable sintered calcium phosphate.

Abstract: An arrangement for the shock-absorbent mounting and support of a dental superstructure, such as a tooth crown, a fastening element for dental bridges and the like, on an artificial tooth having an implantable root and an intermediate member of a tissue-compatible material facilitating a sealing contact with the gingiva, a mounting member for the dental superstructure having a detachable threaded connection interconnecting the intermediate member with the mounting member. A rockable support encompasses the threaded connection so as to form a hollow space there-about, the rockable support extending into a lip sealingly engaged along an outer edge on an upper surface of the intermediate member.

Abstract: An artificial tooth with an implantable root adapted to permanently grow together with the jawbone and, also under high mechanical loads as is the case for natural teeth, will not allow for the production of a rejection or repelling reaction between the natural bone and the implant. The tooth root is essentially constituted of a biostable polymer matrix which is compatible with human tissue, in which there is introduced reabsorbable bioreactive calcium phospate in a finely dispersed form, which is encompassed by a thin porous layer of non-reabsorbable calcium phospate, and into which there is inserted a core as a connecting member for the mounting of a dental superstructure in the form of a tooth crown, a fastening element for dental bridges or the like.
