    Study Notes

    General Surgical Instruments

    • Forceps, elevators, bone chisels, mallets, and curettes are used in oral surgery and may be handled with a pen grasp, inverted pen grasp, palm and thumb grasp, or with a position that requires no rest.

    Four Basic Hand Instruments

    • Mouth mirror, explorer, spoon excavator, and tweezers are essential for oral health care.

    Finger Positions

    • The rest position is assumed with the third and fourth fingers stabilizing the instrument, and the thumb rests on the teeth or gums for support
    • The finger guard position is assumed by the fingers of the non-operating hand to protect the working area.

    Essential Parts of a Hand Instrument

    • The handle or shaft is the part that is grasped by the clinician.
    • The shank connects the shaft to the blade or nib.
    • The blade or nib is the functional end of the instrument.

    Basic Instruments Grasps

    • There are four main grasp types: pen, inverted pen, palm-and-thumb, and a position that requires no rest.

    • Three types of dental chairs are: standard, exodontist's, and child's chair.

    The Dental Unit

    • The dental unit is a fixed appliance responsible for various functions:
      • Cuspidor/spittoon: A receptacle to receive saliva, fluids, and debris.
      • Saliva ejector: A mouthpiece to keep the operating field dry.
      • Tumbler holder: Holds the patient's glass or tumbler.
      • Air syringes: Gives off air blasts to the tooth being treated.
