Abstract

The method involves ionic implantation of controlled amounts of elements suc h as CO, C or O in endo-osseous implants or prosthesis made of metals, metal alloys or biocompatible compound materials. This surface treatment provokes changes in the characteristics of the surface of endo-osseous implants or prosthesis significantly increasing the degree of osseous integration.</SDOA B>

Claims (9)

5. Method according to any one of the previous claims, in which the process of ion implantation is applied on said endo-osseous implants or medical prostheses by means of techniques of line of sight ion implantation or beam ion implantation, plasma immersion ion implantation or plasma source ion implantation, or ion bombardment techniques.
6. Method according to any one of the previous claims, in which the process of inn implantation is carried out at a temperature between -120° C arid 800° C.
7. Method according to any one of the previous claims, in which the endo-osseous implants or the prostheses undergo a thermal treatment at a temperature of between approximately 250° C and 80° C after the process of ion implantation.
8. An endo-osseous implant or medical prostheses.
where at least the surfaces to be in contact with bone are treated, obtainable by means of the method of whatever of the previous claims.
9. Endo-osseous implant or medical prostheses according to claim 8, in which said implant ar prostheses has an enhanced degree of osseointegration, and/or a reduced degree of ionic lixiviation to the physiologic medium in contact with the implant or the prostheses .
