The present invention is based on that 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 said bone tissue. In particular, the invention relates to a bone tissue implant having an implant surface covered by an oxide layer comprising strontium ions and a method for the manufacture thereof. A blasting powder comprising strontium ions, a method for locally increasing bone formation, and the use of strontium ions or a salt thereof for manufacturing a pharmaceutical composition for locally increasing bone formation are also provided by the present invention.
La présente invention concerne l'administration locale d'ions de strontium dans un tissu osseux permettant d'améliorer la formation osseuse et la masse osseuse lors de l'implantation d'un implant de tissu osseux dans ledit tissu osseux. Plus particulièrement, la présente invention concerne un implant de tissu osseux ayant une surface d'implant recouverte par une couche d'oxyde comprenant des ions de strontium et un procédé de fabrication de celui-ci. La présente invention concerne également une poudre abrasive comprenant des ions strontium, un procédé permettant d'améliorer localement la formation osseuse et l'utilisation d'ions de strontium ou d'un sel de ceux-ci pour la fabrication d'une composition pharmaceutique destinée à améliorer localement la formation osseuse.
