The 3D printed denture can clean itself

Thanks to the advancement of 3D printing technology, these new false teeth can kill up to 99% of the bacteria in the mouth without human support.

3D dentures have the ability to self-kill bacteria

If you are not good at dental hygiene, it is very easy to have fillings, even dentures, in the worst case. And then, if you continue to not take care of your new teeth, they can also be broken very quickly.

But, have you ever thought, the dentures you replaced, in the future will be able to self-sterilize? This may happen soon, thanks to medical advances, as well as 3D printing technology.

Scientists in the Netherlands have recently succeeded in creating a false tooth from a bactericidal plastic, thanks to 3D printing technology . This tooth can completely destroy harmful bacteria in the mouth without human support.

"This material can kill bacteria at the time they come into contact with them, but on the other hand, is completely harmless to humans" - Andreas Herrmann, from Groningen University, one of the study members. This project, said.

This tooth is printed from a mixture of Polymers with an antiseptic salt.

Using new materials to replace polymers is still one of the challenges for 3D printing technology. However, the success of adding chemical substances like salt to kill bacteria on these false teeth proved to be a huge step forward for the medical industry.

"We have completed a number of new product models and are ready to test them in the future, including self-sterilizing dentures, orthopedic surgery pads, as well as other replacement parts. Moreover, this bactericidal plastic can also be used for many purposes other than medicine, such as packing food, filtering water, or even making toys for children ".

To test the effectiveness of this resin, the researchers soaked the denture in a mixture of saliva and Streptococcus mutans - the main cause of tooth decay. As a result, 99% of the bacteria are destroyed almost immediately.

"In order to put this type of tooth into practice in practice, we still need to do more tests, especially to check their compatibility with popular toothpaste" - Herrmann share more. His colleagues are very confident about the application of these dentures in the near future: "It is a medical product that will soon be widely applied in dental clinics".
