smart dental implants

Sumary of Smart dental implants:

  • One is a nanoparticle-infused material that resists bacterial colonization.
  • Interfaces and a 2020 paper in the journal Advanced Healthcare Materials, Hwang and colleagues lay out their platform, which could one day be integrated not only into dental implants but other technologies, such as joint replacements, as well.
  • “But once a biomaterial is implanted, it’s not practical to replace or recharge a battery.
  • We are using a piezoelectric material, which can generate electrical power from natural oral motions to supply a light that can conduct phototherapy, and we find that it can successfully protect gingival tissue from bacterial challenge.
  • ” In the paper, the material the researchers explored was barium titanate (BTO), which has piezoelectric properties that are leveraged in applications such as capacitators and transistors, but has not yet been explored as a foundation for anti-infectious implantable biomaterials.
  • Instead, the material generates enhanced negative surface charge that repels the negatively charged cell walls of bacteria.
  • “We wanted an implant material that could resist bacterial growth for a long time because bacterial challenges are not a one-time threat,” Hwang says.
  • The power-generating property of the material was sustained and in tests over time the material did not leach.
