The researchers 3D printed dentures filled with microscopic capsules that periodically release Amphotericin B, an antifungal medication. The study showed that the 3D printed, drug-filled dentures can reduce fungal growth and actually prevent infection, unlike current treatments like antiseptic mouthwashes, baking soda and microwave disinfection. Not only does 3D printing allow for the incorporation of medicines, it allows for the rapid chair-side production of customized dentures, which can take days or weeks using conventional methods. The researchers 3D printed the dentures with acrylamide, which is the current go-to material for dentures. The study looked to determine whether the 3D printed dentures were as strong as conventional ones, and if they could effectively release the medication. Although the 3D printed dentures’ strength was found to be 35 percent less than the conventional ones, they never broke. In the future, the researchers plan to reinforce the strength of the dentures with glass fibers and carbon nanotubes.
