Abstract
A bone implant for implantation into bone tissue includes a metallic material having a surface that is covered by an oxide layer wherein the oxide layer has a thickness within the range of from 2 to 100 nm and includes strontium ions homogenously dispersed in the oxide layer. The oxide layer is a metal oxide layer formed from the metallic surface of the implant. The local administration of strontium ions in bone tissue has been found to improve the bone formation and bone mass upon implantation of a bone tissue implant in the bone tissue.
