The invention relates to an implant for the replacement of a tooth or a part of the bone tissue. It contains metal parts * if strength is required, which is due to a bio-, d. H. Ca-P glass mixture, which adheres to the metal, are protected. The glass is made nonabsorbable by metal oxide additives. In addition, the implant contains a Ca-P glass mixture which is resorbable to the bone or biomass. HA is added to both the resorbable and non-resorbable Ca-P glass so that the blend layers adhere to the fabric, to each other and to the metal as such. The stability of the support of the structure of the invention to the bone is enhanced by the addition of an intermediate layer between the layers farther and closer to the metal, the layer being made of a mixture of slowly resorbable Ca-P-glass and HA. If high strength is not required, the metal core consists of non-resorbable Ca-P glass. When the implant replaces a tooth, the resorbable layer is furthest out and the non-resorbable layer is furthest inside. When the implant according to the invention is used in joints, the innermost layer consists of a mixture of resorbable Ca-P glass and HA and the outermost layer of non-resorbable Ca-P glass. The mixture of Ca-P glass and HA is also used as a spherical filling in bone cavities of the invention. {Implant; Bone tissue; Ca-P-glass mixture; metal oxide additive; biomass; Intermediate layer; Tooth; Bone; Metal core} |
