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.
