Preventing Peri-implantitis: The Quest for a Next Generation of Titanium Dental Implants

“…Yet to be widely accepted/explored, 3D metal printing could play a role in the future manufacture of dental implants . In the field of 3D printing, some interesting developments are being made where patient specific implants could soon be possible. , 3D laser interference nanolithography is another emerging technique, which has the potential to create hierarchical nanostructures on complex curvatures such as on dental implants and abutments which would enhance the mechanical and bactericidal characteristics. , Next generation, smart dental implants (SDI) are also on the rise to combat peri-implant diseases. − Recently, piezoelectric barium titanate embedded dental crowns have been developed for photobiomodulation (PBM) or low-level light therapy (LLLT) which allows the implant to harvest energy from dynamic human oral mechanical motions . The motions power the embedded light emitting diodes (LEDs) placed around the corners of the dental crown.…”

Fully implantable wireless batteryless vascular electronics with printed soft sensors for multiplex sensing of hemodynamics

“…Overall, the development of vascular electronics for arterial sensing has been limited by strict requirements for implantation and operation, including offering sufficient wireless capabilities with a flexible, miniaturized, and low-profile system that affixes itself within an artery and is compatible with minimally invasive catheter implantation. Advances in stretchable and flexible electronics offer a means of forming wireless arterial sensors (13)(14)(15)(16)(17)(18)(19). One recent work targeted vessel anastomosis and demonstrated a cuff-type, flexible pulse sensor that is sutured outside of an artery with a wireless antenna extending outward (17).…”

Three-Dimensional Printable, Highly Conductive Ionic Elastomers for High-Sensitivity Iontronics

“…The rapid growth of flexible electronic devices such as electronic skins, − friction nanogenerators, , and strain sensors − has received unprecedented attention in the fields of human–machine interactions, , soft robotics, and biomedicine. , To meet the needs of more people, flexible electronic devices with multiple functions such as high transparency, flexibility, stretchability, stability, and ion conductivity are required. In recent years, ionic conductors have gradually been widely researched instead of electronic conductors.…”
