Because of FlexiWedge's® unique design, care should be taken to pick the largest wedge that will go into place. If you find that the wedge backs out easily, you should select a larger size wedge. The flexible sidewalls of FlexiWedge® will adapt to concavities or any other surface irregularities. On the other hand, a wooden wedge (lower image) does not have the capability to adapt itself to these irregularities.
The technique for the placement of FlexiWedge® is quite different from wooden wedges. To place correctly, FlexiWedge® should be grasped on the inferior and superior aspect of the wedge handle with strong college pliers, hemostat, Howe pliers or similar-type instrument. Pliers must be strong enough to grasp and drive the wedge.
Driving force, plus a gentle up and down rocking motion, will ratchet the wedge into the correct position. Again, if you find that the wedge backs out easily, select a larger size wedge.
Improper Wedge Placement Important! Do not use cotton forceps to drive the wedge. When the handle of the cotton forceps is used, the wedge will simply bend.
Also, do not use your finger to place or drive the wedge, as this technique does not deliver enough force to drive the proper size wedge into place.
