Abstract
The invention relates to an implant for the human or animal body, which on its outer surface comprises at least one calcium salt that is soluble in a polar liquid. The invention also refers to various methods for the preparation of the preceding implant. The calcium ions contained on the surface of the implant provide said surface with four chemically and biologically advantageous properties: hydrophilicity, protection against atmospheric contamination, a pro-coagulant property and a pro-mineralising property.
Claims18
Implant for the human or animal body, wherein the outer surface of the implant comprises at least one calcium salt that is soluble in a polar liquid.
Method for modifying the surface of an implant, comprising the following steps:
- immersing the implant in a solution of at least one polar-liquid-soluble calcium salt,
- removing the implant, with the result that the polar-liquid-soluble calcium salt is deposited on the implant surface,
- storing the implant in a container inside which there is a dry atmosphere, the implant coming into contact with dry atmosphere.
Method for modifying the surface of an implant, comprising the following steps:
- immersing the implant in a solution of at least one polar-liquid-soluble calcium salt,
- removing the implant, with the result that the polar-liquid-soluble calcium salt is deposited on the implant surface,
- storing the implant in a container inside which there is an ambient atmosphere, the implant coming into contact with said ambient atmosphere.
Method for modifying the surface of an implant, comprising the step of storing the implant in a container that contains a solution of at least one polar-liquid-soluble calcium salt, the implant being stored in contact with said solution and insulated from the outside, where the concentration of the solution of at least one polar-liquid-soluble calcium salt is between 20 and 2000 mM.
