Patent number: 8734889Abstract: The invention relates to a ceramic implant, especially a dental implant, comprising a structured or porous surface for at least partially inserting into a bone. An especially advantageous surface is obtained when it is at least partially modified by a salt melt. These excellent osteointegration properties can be obtained by a method whereby the surface is modified in a salt melt at least in the regions exposed to the bones and/or soft tissue, optionally following a previous modification of the surface whereby material has been removed.Type: GrantFiled: June 1, 2006Date of Patent: May 27, 2014Assignee: Thommen Medical AGInventors: Falko Schlottig, Thomas Hefti

Publication number: 20140131909Abstract: A biologic artificial bone includes an artificial fiber material formed from a synthetic polymer with mechanical properties similar to type I collagen. A biocompatible liquid substance is impregnated in the fiber material that hardens and stiffens the fiber material. A bone substitute is impregnated in the hardened and stiffened fiber material forming an artificial bone composite. Vascular channels are formed in the artificial bone composite to facilitate in-growth of vessels and bone forming cells. The construction and methods achieve an artificial composite structure that is similar to natural bone with comparable properties.Type: ApplicationFiled: January 21, 2014Publication date: May 15, 2014Inventor: Said G. Osman
