Stem cell heart surgery may spell the end for transplantation
British scientists have developed a new technique that can rebuild a severely damaged heart, and one day, might replace the need for transplantation. ANI
A new insight into the turbulent atmosphere of Venus
New images taken by instruments on board ESAs (European Space Agencys) Venus Express have provided insight into the turbulent atmosphere of our neighbouring planet. ANI
ESA tests laser to measure atmospheric CO2
A recent ESA (European Space Agency) campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide (CO2) in the atmosphere. ANI
University of Bristol researchers will fix copies of real human teeth on a set of robotic jaws this year to test how materials would wear in the mouths of individual people.
London, January 4 : University of Bristol researchers will fix copies of real human teeth on a set of robotic jaws this year to test how materials would wear in the mouths of individual people.
Dento-Munch, which mimics the full movement of the human jaw, has been created by engineer Kazem Alemzadeh. The lower robotic jaw is able to make up and down, forward and backwards, and left and right movements.
Alemzadeh is now thinking of creating accurate copies of human teeth for Dento-Munch to chew with.
He will scan standard plaster casts of teeth made by dentists using an office projector, a digital camera, and some custom software. The detailed 3D digital copies will then be used to machine replicas later loaded into the jaw.
The 3D scanning system to be used by Alemzadeh is called Dento-OS. It uses an approach known as structured light, wherein a pattern of light and dark bands is projected onto the surface to be scanned.
"It has got to be as real as possible. We also will capture the motion of chewing to test how materials would wear in the mouths of individual people," New Scientist magazine quoted Alemzadeh as saying.
Motion of chewing captured by the researchers will be used to record jaw movements using attached fluorescent spots tracked by cameras.
Alemzadeh believes that his technique will be highly accurate in registering chewing motions.
