Figure 3. Preformed .032 Nance Crib is placed in .036 lingual sheaths of the upper molar bands. Due to the molar tipping, the wire is away from the palatal rugae.

Figure 4. The area where the Nance button will be placed is thoroughly dried. Ideally, the acrylic button is placed at the most vertical portion of the palatal vault.

Figure 5. A small ball of light-set acrylic (approximatetly one cm in diameter) is placed under the retentive bends in the Nance crib.

Figure 6. A three pronged plier is used to bend the crib down into the soft acrylic. The bends are made on the right and left sides as close as possible to the lingual molar sheaths. Bending the crib into the acrylic prevents creating a void underneath the button.

Figure 7. The acrylic button is first flattended, shaped and rounded with moist finger pressure. It can be further contoured for comfort using a Teflon spatula (product of Dentsply Corp.).

Figure 8. The acrylic is set using a light source in four 20-second increments. To prevent heat buildup, wait five seconds between each burst of light.

Figure 9. The Quick-Nance in place immediately following removal of the Pendex Appliance.

Figure 10. Quick-Nance in place with the upper arch bonded. The upper molars have been overcorrected, stops are bent mesial to the buccal tubes and a short-term, high-pull headgear is being worn to further bolster anchorage while the upper buccal segments are retracted.
