patient's chin. As an assistant, you must anticipate the
dentist's needs and be ready when signaled by the
dentist to pass the next instrument and receive the used
one in a smooth motion.
Double-handled instruments, such as scissors,
hemostats, and forceps, along with single-ended
instruments with bulb-type handles, such as
elevators, are transferred somewhat differently as
discussed in previous chapters. As figures 5-46 and
5-47 illustrate, when passing these types of
instruments, grasp the working end and place the
handle into the palm of the dentist's hand. The
working end of the passed instrument should be
pointed toward the correct arch. When the dentist
finishes with the instrument, you will receive the
instrument by grasping the working end.
SURGICAL AIR DRILL
Many different makes and models of surgical air
drills are used in oral surgery. A common surgical air
drill used in the Navy is shown in figure 5-48. It is a
high-speed hand piece used in oral surgery procedures
to remove bone and section teeth. The drill enables the
dentist to accomplish these procedures quickly and
reduces the trauma to oral tissues. It operates by a hand
control lever while other makes and models operate by
a foot pedal.
Bur guards (fig. 5-49) are used with the air drill.
Surgical burs are then inserted into the drill after the
bur guard is in place. Bur guards are available in three
lengths: medium, long, and extra long. They are
designed to protect the dentist and the patient from the
long shaft of the burs. Selection of a bur guard is
directly dependent on the length of the bur to be used.
