| Dental ChairsWhat does it doDental chairs provide a platform from which a dentist can safely and comfortably perform oral surgery and examination with all the necessary instruments and functions close at handHow it worksTypical dental chairs are hydraulically operated so they can be raised, lowered and also laid down to a horizontal position. Incorporated into the chair are High and low speed dental drills, air and water sprays (syringes) to wash debris from the area being worked on and also a suction system to remove water and debris. High speed dental drills are usually air driven turbines, whereas low speed drills need more torque and are generally electric motor driven. Dental drills also have water sprays to cool the area, which is being cut away. Water that is used for irrigation is normally distilled or at least filtered to avoid unnecessary contamination. A water and amalgam separator is also used to prevent solids from clogging the drainage systemUnits of measurementPressure: for example mmHg & kPa | |
