Abstract
Abstract A method of preparing an implant body in order to optimize the healing time of said implant, comprising bringing the implant body for a limited period of time into contact with a hydrogen peroxide solution at least on the surfaces intended to come into contact with surrounding tissue when implanted, the treated surfaces being cleaned by rinsing. The treatment of the implant surface with hydrogen peroxide can be supplemented with incorporation of biomolecules, such as peptides, proteins and steroids, and also other substances such as inorganic ions and crystals. The compounds to be coupled to the implant surface may promote the healing and/or binding of the surrounding tissue.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
75 words
A method of preparing an implant body for implantation, said implant consisting of titanium or being coated with titanium, comprising contacting the implant body with a hydrogen peroxide solution at least at the surfaces intended to come into contact with surrounding tissue when implanted, for a time sufficient to form a surface layer of hydrated oxide with peroxide and superoxide incorporated in a polymeric structure, and then rinsing said surfaces without removing said surface layer.
Claim 2
Independent Claim
75 words
A method of preparing an implant body for implantation, said implant consisting of titanium or being coated with titanium, comprising contacting the implant body with a hydrogen peroxide solution at least at the surfaces intended to come into contact with surrounding tissue when implanted, for a time sufficient to form a surface layer of hydrated oxide with peroxide and superoxide incorporated in a polymeric structure, and then rinsing said surfaces without removing said surface layer.
Claim 3
Dependent Claim
16 words
A method as claimed in claim 1, wherein said hydrogen peroxide solution is a 1-30% solution.
Claim 4
Dependent Claim
19 words
A method as claimed in claim 2, wherein said implant surfaces are immersed in said 1-30% hydrogen peroxide solution.
Claim 5
Dependent Claim
21 words
A method as claimed in claim 2, wherein said implant surfaces are painted or sprayed with said 1-30% hydrogen peroxide solution.
Claim 6
Dependent Claim
27 words
A method as claimed in claim 2, wherein, after rinsing, the implant body is stored in an inert environment until it is to be used for implantation.
Claim 7
Dependent Claim
13 words
A method as claimed in claim 5, wherein said inert environment is water.
Claim 8
Dependent Claim
19 words
A method as claimed in claim 2, wherein water or a salt solution is used as the rinsing liquid.
Claim 9
Dependent Claim
25 words
A method as claimed in claim 2, wherein the duration of contact for the implant body with the treating liquid is at least 1 minute.
Claim 10
Dependent Claim
15 words
A method as claimed in claim 8, wherein said duration of contact is 1-30 minutes.
