Background: Increasing evidence implicates biofilms, consisting of species such as Porphyromonas gingivalis (Pg), in the etiology of peri-implantitis. Multiple approaches to ablate biofilms on failing implants have been proposed and include use of lasers, most recently the erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser. The purpose of this study is to establish an in vitro single-species biofilm model on implant surfaces and determine power settings of the Er,Cr:YSGG laser that remove biofilm without causing physical damage to disks.

Article Synopsis
  • The rising demand for orthodontic treatments is increasing the need for acrylic resins in removable appliances and retainers, which can lead to higher risks of oral infections due to bacterial and fungal biofilms.
  • A new antibacterial and antifungal material, quaternary ammonium methacryloxy silicate (QAMS), was developed by modifying silicate with methacryloloxy functionalities and is copolymerized with polymethyl methacrylate in resin.
  • The QAMS-enhanced acrylic resins showed effective antimicrobial properties against specific bacteria and fungi while also offering improvements in toughness and resistance to water, making them a significant advancement for reducing infections during orthodontic appliance use.
