Chewing Robot' could revolutionise dental research

A 'Chewing Robot' which mimics the human jaw and teeth could revolutionise dental research, it has emerged. Published: 7:00AM BST 30 Jun 2009 The mechanical mandible allows experts to study the wear-and-tear on dental fittings like crowns and bridges without using costly human subjects. Fittings are made from well-known metals, polymers and ceramics – but their dental wear properties are often poorly understood.

By the time a new material has been tested, it is often obsolete. This is where the Chewing Robot – created by the University of Bristol and the Department of Oral and Dental Science – comes in. The movements and

While they do stretch the metaphor a bit, the group's TLEMsafe system does provide surgeons with a complete 3D map of the lower body, which can actually be personalized for each individual patient, giving surgeons a reference and means to practice before any actual surgery takes place -- and, yes, even an "automated navigation system" during surgery. Coincidentally, some researchers from the University of Colorado have also just announced that they've
