Metal sponge-like structure and method for making the same

Abstract

Abstract The invention relates to a metal sponge-like structure of titanium or tantalum or alloys thereof and to a method for producing the metal sponge-like structure. The metal sponge-like structure is in the form of an open-cell wire-lattice structure, whose entire surface is microstructured and bioactive. The metal sponge-like structure serves as a bone replacement in emergency surgery and orthopaedics and becomes incorporated without connective tissue. The cavities can be filled completely or partially with resorbable biomaterials. The method for producing the metal sponge-like structure is used in medical technology and permits a patient-specific adaptation of a permanent implant in the form of a metal sponge-like structure also with differentiated density distribution made of high-melting reactive metals, which is obtained by remodelling, different perforation of the starting material or by different layer thickness.
