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 position.
