Figure 5-23.Cogswell A and B root elevators.
Miller #73 and #74 elevators, shown in figure 5-24,
have curved, thin working ends with smooth, rounded
tips. These elevators are designed to elevate a tooth or
large root fragment. The Seldins #1L and #1R, shown
in figure 5-25, have sharp-tipped working ends with an
abrupt 90-degree angle. The Seldins, sometime
referred to as East- West elevators, are designed for use
on molar roots. The Cryer #25 and #26 are similar to
the #1L and #1R Seldins; however, the working ends
are angled at angles greater than 90 degrees (fig. 5-26).
APICAL ROOT TIP PICK ELEVATORS
This group of elevators are used to remove fractured
root tips lodged deep in the root socket. These
elevators are often called root picks. Elevators that
make up this group are the #5 and #6 West, and the #9
apical, #9L, and #9R. The working ends on these
elevators are very thin, sharply pointed, and small. The

#5 and #6 West, shown in figure 5-27, have much
shorter shanks and are designed to remove extremely
small apical fragments. The #9L and #9R are set at left
and right angles to the handles (fig. 5-28). The handles
are also small in diameter but longer than those on
other elevators discussed earlier.
The facial bone that forms the cheek is called the
zygoma or malar bone. An injury to this bone often
causes a depressed fracture. If this occurs, the dentist
will use a malar elevator to raise the bone to its normal
