Smiling student uses 3D printer to make plastic braces on the cheap

Orthodontics don't tend to mix too well with self-sustaining undergraduate students, whose budgetary extravagances might extend to the odd double serving of instant noodles. But faced with crooked teeth and access to a 3D printer, digital design student Amos Dudley has taken matters into his own hands, straightening out his smile with a set of DIY plastic aligners.

Graphene shows promise for super strong dental fillings

A team of researchers from four institutions located in Romania and St. Kitts have worked together to determine whether graphene could be used to create more durable dental materials. They worked to test how toxic different forms of the material were to teeth, with promising results.Read More

3D Printing

3D printed teeth kill bacteria

Creating replacement parts for various bits of the human body is one of the many areas in which 3D printing has huge potential. Dental implants are on that list, too, and if new research out of the University of Groningen in the Netherlands comes to fruition, 3D-printed replacement teeth could come with the added bonus of being able to destroy 99 percent of bacteria that they come into contact with.Read More
