Attaching an Elastomeric Chain to a Soldered Lingual Arch
Volume 57 : Number 11 : Page 693 : Nov 2023
An elastomeric chain cannot normally be attached to a lingual arch without the addition of soldered hooks. In this alternative method, a link of chain is pulled through the other end to wrap around the arch for eruption of an impacted canine.

Simultaneous Canine Alignment and Extrusion with a Cantilever and Step Bend
Volume 59 : Number 7 : Page 465 : Jul 2025
Traditional methods of repositioning canines during leveling and alignment may require several bracket readjustments. This Pearl eliminates the need for bracket repositioning with a simplified double-archwire technique that combines a step bend with a cantilever for simultaneous canine alignment and extrusion.

Modified Transpalatal Arch for Simultaneous Intrusion and Retraction
Volume 52 : Number 8 : Page 439 : Aug 2018
Miniscrews are commonly placed in the buccal dentoalveolus, mesial to the maxillary first molars, to anchor simultaneous intrusion and retraction of the anterior teeth. This simple Pearl takes us back to a tried-and-true alternative: a modified transpalatal arch with soldered buccal arms in place of miniscrews.

Measuring Digital Torque with a Smartphone
Volume 53 : Number 9 : Page 537 : Sep 2019
Smartphones now have built-in features for calculating angles and tilt. The author shows how to attach a ribbon arch plier to a spare phone case to measure the exact amount of torque being added to an archwire, using a free smartphone app.

Easy Reactivation Loops for Forsus Devices
Volume 53 : Number 10 : Page 602 : Oct 2019
The author presents a simple technique involving the use of looped .017" × .025" stainless steel wire, bent with a bird-beak plier, as an alternative to metal shims for reactivation of Forsus Fatigue Resistant Devices.

The "Sashette" Attachment for Correcting Severely Rotated Upper Central Incisors
Volume 59 : Number 10 : Page 678 : Oct 2025
Dr. Nicozisis introduces a variation on his “sash” attachment designed specifically for upper central incisors. Placing these smaller attachments in the incisal third reduces visibility while improving rotational control during clear aligner treatment.

Etching Mask for Invisalign Attachments
Volume 54 : Number 3 : Page 173 : Mar 2020
A duplicate attachment template tray is ordered from Align Technology and then modified with a scalpel to remove the composite wells. The modified tray is used as a mask to control etchant placement and thus limit the amount of flash, simplifying the bonding appointment.

Inclusion of Lingual Tongue Spurs in Clear Aligners
Volume 54 : Number 7 : Page 429 : Jul 2020
Metal tongue spurs for correction of a tongue-thrust habit are difficult to incorporate in aligner treatment. This Pearl shows how to stack lingual attachments in the virtual setup and then sharpen the unfilled wells to create tongue spurs in the aligner trays.

The Miniscrew-Anchored Cantilever: A Simple Molar Distalizer
Volume 54 : Number 12 : Page 773 : Dec 2020
A device for “noncompliance” Class II treatment is easily constructed by attaching an .040" cantilever wire between a miniscrew and a molar headgear tube. Distal force is obtained from a nickel titanium closed-coil spring, while the direct skeletal anchorage prevents unwanted side effects on the anterior teeth.

Minimizing Side Effects During Canine Extrusion with Twin Brackets
Volume 55 : Number 9 : Page 559 : Sep 2021
Canine extrusion can cause unwanted intrusion of the adjacent lateral incisor and first premolar, especially when twin brackets are used. In this Pearl, a “floating O-ring” engages the archwire beneath the bracket, avoiding the generation of a vertical force vector on neighboring teeth.

Active Expander Arms for Anterior Crossbite Resolution
Volume 56 : Number 3 : Page 185 : Mar 2022
This Pearl demonstrate the addition of active .035" cobalt chrome anterior extensions to a rapid palatal expander for correction of an anterior crossbite associated with a skeletal Class III malocclusion. Other appliances can be applied simultaneously for alignment.
