Eraser Plier

Eraser Plier

The Eraser Plier (Article# LS8-139) is built from surgical-grade stainless steel with a satin finish across the body and handles. Its defining feature is a pair of broad, flat opposing jaw faces, wider than standard aligner pliers, engineered to distribute even compressive force across the targeted thermoplastic aligner surface. A box-joint pivot connects the two elongated handle arms, providing stable, controlled jaw closure. Both flat beak surfaces are precision-smoothed to contact and compress aligner indentations without scoring, tearing, or distorting the surrounding plastic material.

The instrument operates entirely at room temperature, requiring no tip heating prior to use, unlike forming pliers in the same system. The Aligner Pliers Eraser reduces the depth of an existing pressure point or removes it entirely by pressing the flat jaw faces squarely against the affected aligner surface. The stainless-steel construction resists corrosion across repeated sterilization cycles, and the instrument is fully autoclavable at standard steam sterilization temperatures, supporting multipatient clinical reuse without degradation of the jaw geometry.

Orthodontists use the Eraser Plier during clear aligner therapy to correct inaccurately placed indentations created by dimple, vertical, horizontal, or tear-drop punch pliers. When a force point has been placed at the wrong tooth position, or when a previously needed activation is no longer required at a given treatment stage, the clinician positions the flat jaws over the affected indent and applies firm, even pressure to flatten the thermoplastic back toward its original contour, restoring correct aligner fit without reordering a replacement tray.

Leader Surgical equips orthodontic practices with instruments that solve real chairside problems, and this Plier stands as proof of that practical approach, saving clinicians time and patients the inconvenience of delayed treatment from avoidable tray remakes.

What is the primary use of an Eraser Plier?
It is used to remove or flatten unwanted indentations, bumps, or dimples in clear aligners. These indents are often created by other detailing pliers, such as teardrop or vertical pliers, that may no longer be necessary or were incorrectly placed.
