robotlyra:swampgallows:malformalady:Researchers at the University of Groningen in Holland are developing 3D-printed teeth from an antimicrobial plastic. The 3D printed teeth could solve a lot of these problems, as they would remain white and pristine regardless of care. The teeth will be made of antimicrobial quaternary ammonium salts integrated into dental resin polymers. When positively charged, the salts can cause bacterial membranes to burst and die. The researchers created the blend with a 3D printer and hardened it with ultraviolet light. They printed sample materials including replacement teeth and braces. As part of the research, they coated the objects with saliva and Streptococcus mutans for 6 days. The bacteria is common in the oral cavity and enables tooth decay.
