Toothbrushes 3D technology

Using three-dimensional technology, engineers in Spain have developed a toothbrush that cleans teeth for each person's mouth.

At first glance, Blizzid's 3D toothbrush looks like a full-length denture, but it is said to clean the teeth completely for six seconds, Livescience reported.

Before making a personalized brush, the manufacturer uses a digital dental scanner to determine the optimal position of the 600 brush hairs by simulating biting and chewing movements. These bristles are similar to normal toothbrushes, but they are smooth and tapered to reach the bottom of the gingival margin and better teeth.

They then use a dental scanner to create a computer-aided design (CAD) model, which transforms into a real object using a 3D printer using stereolithography , a method in which plastics Liquid is formed by ultraviolet laser.

"To brush your teeth with a 3D brush, the user just bites down on it and grinds for 6 seconds. This chewing motion is effective, in that the brush is at a 45 degree angle or perpendicular to the foot. teeth and brush back and forth in larger circles than conventional brushes, " says 3D brush makers.
