                   Technology Reduces Time in Dentist's Chair

   Medical robots help surgeons perform delicate operations more safely
   and with greater dexterity than with instruments manipulated by hand.
   These sophisticated tools also help doctors work more quickly. One such
   machine reduces the time it takes to manufacture dental crowns to just
   a couple of hours. VOA's George Putic has more.
