Researchers develop 3D printed teeth capable of fighting 99% of oral bacteria
Researchers at the University of Groningen in the Netherlands headed by Andreas Herrmann have come-up with 3D printed teeth material that kills bacteria. This revolutionary new teeth design is 3D printed using an antimicrobial plastic using stereolithographic process which eliminates a major problem of tooth decay and saves your teeth from any major damage. Effectively this material helps greatly in killing 99% of bacterium Streptococus mutans which is the major cause of tooth decay.
This material has antimicrobial quaternary ammonium salts which are positively charged and disrupt the formation of negatively charged bacteria that are eliminated as soon as they contact the tooth. On top of it all, the material is not harmful to human cells in any way which is a major concern since it comes in direct contact with mouth cells.
The new material can be used in replacement of teeth, orthodontic braces or one day may even be used in dental hygiene products like toothpaste or mouthwash. Researchers are hard at work in strengthening the material so that it can be used as a complete replacement for existing tooth. Currently they have developed a salt and polymer mix which is put into a 3D printer and then hardened with UV light in the desired shape.
They put the mix in saliva and bacteria for six days to achieve this result and further testing is needed before this new material can be used of dental applications. The research seems to be heading in the right direction and soon we’ll see its application in medical science and over-the-top dental medications.
