Patent number: 11000627Abstract: The present invention relates to a process of treating an implant, comprising a step of treating the surface of the implant with at least one phosphonic acid compound or a pharmaceutically acceptable salt, ester or amide thereof under sonication at a temperature of about 50° C. to about 90° C. This process is highly advantageous in that it allows the formation of a monolayer of the phosphonic acid compound on the implant surface, having a particularly dense surface coverage which, in turn, results in an improved implant biocompatibility and improved osseointegration.Type: GrantFiled: February 13, 2017Date of Patent: May 11, 2021Assignee: NANO BRIDGING MOLECULES SAInventors: Sabrina Buchini, Richard Curno, Björn-Owe Aronsson, Péter Péchy

Patent number: 5697997Abstract: A method for preparing implant surfaces using gas discharge plasma including conveying the implants to a vacuum chamber. The implants are treated with an inert gas plasma to remove existing surface contamination and oxide layers from the implant surfaces. The implants are treated with an oxidizing plasma or by means of thermal oxidation to reoxidizing the implant surfaces. The implant treatment steps are carried out in a closed space, including a controlled atmosphere and produce a highly accurate and reproducible microstructure, composition, purity, and sterility in the implants.Type: GrantFiled: May 9, 1996Date of Patent: December 16, 1997Assignee: Nobel Biocare ABInventors: Bjorn-Owe Aronsson, Patrik Johansson, Bengt Kasemo, Jukka Lausmaa
