(ED NOTE: This post may not seem relevant to our aim of enlightening readers on the latest developments  in Digital Healthcare, but that is not so.  First, it shows the potential of an up-and-coming technology, like 3-D printing, and scanning to accomplish delicate health-related tasks, i.e. health of teeth.  And secondly,poor oral hygiene has been linked to an increase in incidence of oral cancers.)

One of the great advantages of 3D Printing is the ability to design and create customized versions of everyday objects. Engineers from Blizzident have invented a new kind of toothbrush that is tailor-made to fit into a person’s mouth using 3D scanning and 3D printing.

According to the company, By simply biting and grinding, Blizzident automatically cleans all teeth perfectly within six seconds, and you can even floss and clean your tongue at the same time.

How it works:

All Blizzident-bristles are tailored to your own teeth. They are placed on the surface of your teeth in a 45 degree angle. They are also aligned exactly along your gumline in a 45 degree angle. Additionally there are interdental bristles between all your teeth.

How to get a Blizzident:

To make the brush, the dentist takes an impression of all your teeth (with biting position) or scans them directly (thus creating a digital 3D model directly) and then uploaded to Blizzident. The makers need to find out the optimal placement of 600 bristles by simulating biting and chewing movements and then create a computer aided design (CAD) model of the brush accordingly. The brush is then printed out using 3D printing, to be precise here, stereolithography technology, which employs a vat of liquid ultraviolet curable photopolymer “resin” and an ultraviolet laser to build parts’ layers one at a time.

How to use a Blizzident:

To brush with the Blizzident, you simply bite down on it and grind your teeth for about six seconds. The biting motion achieves the same effect as the two common teeth cleaning motions — the Modified Bass technique, in which the brush is positioned at a 45-degree angle to the teeth and moved back and forth, and the Fones technique, in which the brush is held at right angles to the teeth and moved circularly.

The tailor-made 3D printed toothbrush is now available online for $/€299. Prices of direct scan or impression+digitizing range between $75 and $200, but the company says this invention could actually save people money in dental costs, as well as saving time spending on brushing and flossing teeth. the Blizzident lasts one year, you can then buy a refurbished one for 89.- $/€ and a completely new one for 159.- $/€.
