  • Biocompatible component
    Patent number: 10052404
    Abstract: The invention provides a biocompatible component having a surface intended for contact with living tissue, wherein the surface comprises particles of metal oxide, said particles having an average particle size of less than 100 nm.
    Type: Grant
    Filed: May 10, 2012
    Date of Patent: August 21, 2018
    Assignee: Dentsply Sirona Inc.
    Inventors: Elisabet Ahlberg, Ingela Mattisson, Johanna Löberg
  • Medical device having a surface comprising nanoparticles
    Patent number: 9889237
    Abstract: A medical device has a surface intended for contact with living tissue, wherein the surface comprises nanoparticles comprising a non-toxic post-transition metal such as gallium and/or bismuth, said nanoparticles having an average particle size of 500 nm or less. The nanoparticles may provide an antimicrobial effect, and thus the risk for infection may be reduced.
    Type: Grant

  • BIOCOMPATIBLE COMPONENT
    Publication number: 20120288699
    Abstract: The invention provides a biocompatible component having a surface intended for contact with living tissue, wherein the surface comprises particles of metal oxide, said particles having an average particle size of less than 100 nm. A method for the production of such biocompatible component is also provided. It was found that the bioactivity of the biocompatible component was increased compare to a reference in that it induced earlier apatite nucleation in vitro. It is believed that by the biocompatible component may induce early hydroxyapatite nucleation in vivo and thus promote osseointegration of an implant.
