Superficial structure on surface of prosthetic implants made of titanium metal or titanium based alloy

For medical prosthetic implants made of titanium metal, or titanium-based alloy the structure of the surface, that is the surface morphology and composition, are crucial factors from the point of view of the short range as well as long range efficiency of the implantation. The superficial structure,...

Beschreibung
Zusammenfassung:	For medical prosthetic implants made of titanium metal, or titanium-based alloy the structure of the surface, that is the surface morphology and composition, are crucial factors from the point of view of the short range as well as long range efficiency of the implantation. The superficial structure, to which the invention relates, morphologicaly consists of partly regular partly irregular macromorphological elements of 10-50 mu m size which are izomorphic with a plane and dentritic micromorphological elements of less then 1 mu m size over the whole surface which are similar to imprints of acicular pine-needles. The superficial composition of the prosthetic implant is either identical with the bulk composition or practicably changed. The superficial structure, according to the invention, is produced by using high-energy laser pulse either in vacuum or in an environment consisting of suitable materials.
