A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
A new tool being developed by the University of Copenhagen and 3Shape will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.
"Our simulation is able to let an orthodontist know where braces should and shouldn't exert pressure to straighten teeth. Currently, these interventions are based entirely upon the discretion of orthodontists and involve a great deal of trial and error.
"As transparent aligners are softer than metal braces, calculating how much force it takes to move the teeth becomes even more complicated. But it's a factor that we've taught our model to take into account, so that one can predict tooth movements when using aligners as well," says Torkan Gholamalizadeh.
"Right now, we have a database of digital patients that, besides simulating aligner designs, can be used for hip implants, among other things. In the long run, this could make life easier for patients and save resources for society," says Kenny Erleben. "The virtual model can answer what's happening in the real world, and do so instantly. For example, one can ask what would happen if you pushed on one tooth and get answers with regards to where it would move and how it would affect other teeth. This can be done quickly, so that you know what's happening. Today, weeks must pass before finding out whether a desired effect has been achieved," says Professor Kenny Erleben.

How fear unfolds inside our brains | ScienceDailyThe stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats -- such as in PTSD -- have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circuitry that cause generalized fear experiences.
