GENERAL FEATURES OF DENTAL INSTRUMENTS

FIGURE 3.1

Working end(s) of instruments

  • Are the functional parts of the instrument
  • Can have a variety of functions including cutting, packing, carving, placing and condensing
  • Are adapted to the function of the particular instrument
  • May be bevelled (i.e. the working end is cut at an angle)
  • An instrument can be single-ended (one working end) or double-ended (two working ends)

Shank of an instrument

  • The part between the working end and the handle
  • Can be straight or angled
  • The function of the instrument determines the angle and flexibility of the shank

Handle of an instrument

  • Is the part of the instrument that the operator grasps
  • Provides stability and leverage
  • Design is related to the function of the instrument
  • Examples:
    • The handle of an upper extraction forceps may be curved to facilitate a palm grasp for the operator
    • The handle of a rubber dam clamp forceps is rounded to fit in the palm of the operator’s hand
    • A serrated handle allows a better grip
    • A large handle allows a palm grasp
