  • Publication number: 20050221258
    Abstract: An implant (10) has one or more surfaces (10a, 10b) with a basic or starting surface structure (1a) derived from mechanical working. A topographic modification of the surface structures is arranged on said surface structure or surface structures. The topographic modification can be formed, for example, by means of shot-peening, etching, plasma spraying, chemical action, etc. The topographically modified surface structures support bone-growth-stimulating agent. In a method for producing the implant, three subsidiary methods are used for carrying out the mechanical working, the topographical modification, and the application of the bone-growth-stimulating agent. An important niche in the demand which exists in the field of implants is thus covered in an advantageous manner.

  • Publication number: 20050208454
    Abstract: The stability of an implant (5) which is fitted in a jaw bone hole created by tooth root extraction is increased using osteoinductive material. Bone formation in the space between the implant and the bone wall is also stimulated. In an initial stage, the implant is anchored or fitted in the hole. With its outer parts (5a) the implant extends into a part (4a) of the hole which has a cross-sectional area exceeding the cross-sectional area of the outer parts (5a) of the implant. The soft tissue of the jaw bone, with possible periosteum, covers the implant and the space to form a closed space (4a). The bioactive material consists of growth-stimulating substances (GSS) arranged on the implant In a stage of incorporation, GSS passes outward into body fluid which has penetrated into the closed space and interacts with cells present in the fluid so that new bone is formed around the outer parts (5a) of the implant. The invention also relates to a use and to an implant.
