Active Nickel Titanium Lingual Retainer for Minor Tooth Movement
Volume 51 : Number 5 : Page 308 : May 2018
Incisor crowding can relapse even when lingual retainers are bonded or when patients are dedicated in wearing removable retainers. This Pearl reviews the use of an “active” nickel titanium lingual retainer to achieve minor recorrections without the need for compliance.

Measuring the Torque on the Terminal End of an Archwire
Volume 52 : Number 0 : Page 346 : Jun 2018
An orthodontist sometimes needs to add buccal root torque to the finishing archwire to resolve a hanging palatal molar cusp. This Pearl shows how a standard plastic protractor can be modified to precisely determine the amount of torque on the terminal end of the wire.

Bonded Attachment for Severely Rotated Teeth
Volume 52 : Number 9 : Page 476 : Sep 2018
When a tooth is severely rotated, the lack of accessible surface area can make it difficult to bond an attachment. The Jadex eyelet, fabricated at the chair from stainless steel ligature wire, is easily bonded to achieve quick derotation.

Modified Bite-Block Rapid Maxillary Expander
Volume 53 : Number 1 : Page 53 : Jan 2019
Rather than bonding the acrylic pads of a bite-block expander to the teeth, the authors band this appliance to the second deciduous molars. A pivotal opening allows the patient to perform oral hygiene.

Avoiding Yellow Discoloration of Clear Elastomeric Modules
Volume 53 : Number 2 : Page 115 : Feb 2019
Unsightly yellowing of clear elastomeric ligatures from food products such as mustard or curry is a common concern among patients wearing ceramic brackets. The authors propose using pale lavender ligature ties, which turn a neutral off-white when combined with yellow.

Composite Build-Up of Infraoccluded Second Deciduous Molars
Volume 53 : Number 5 : Page 290 : May 2019
Lack of a successor to a lower second deciduous molar can cause supraeruption of the opposing upper premolar. This Pearl shows how to add flowable resin to the infraoccluded deciduous molar to restore function and esthetics during the retention phase.

Inserting Auxiliary Springs into the Acrylic of Rapid Palatal Expanders
Volume 53 : Number 6 : Page 355 : Jun 2019
This Pearl shows how to add a removable finger spring to a standard Haas expander by embedding a tube into the acrylic. The spring can then be used to correct simple problems such as anterior crossbite or midline shift during the passive stabilization period after expansion.

An Alternative Technique for Miniscrew-Assisted Rapid Palatal Expander Fabrication and Placement
Volume 53 : Number 11 : Page 669 : Nov 2019
The authors’ vacuformed plastic surgical guide allows a boneborne MARPE to be employed without the extension arms, which reportedly cause some dental expansion. A simple procedure for fabrication and placement of the appliance is described and illustrated.

Intruding a Single Overerupted Tooth with a Modified Clear Removable Tray
Volume 59 : Number 12 : Page 808 : Dec 2025
As an alternative to more complicated approaches for intrusion of a single tooth, a clear tray is modified with scissor cuts, allowing the patient to hook a small elastic on the lingual side of the tray, stretch it across the occlusal surface, and hook it on the buccal side.

Simple and Secure Ligation Technique for Anterior Intrusion Using a Miniscrew
Volume 54 : Number 2 : Page 121 : Feb 2020
In this Pearl, an elastomeric chain is engaged from a palatal miniscrew head to two gingivally oriented loops on the main archwire. The resulting upper incisor intrusion can rapidly close a midline diastema without the need for frequent reactivation.

Volume 55 : Number 8 : Page 497 : Aug 2021
A ligature cutter is commonly used instead of a distal-end cutter to trim a short protruding wire. The authors show how to make a safety mechanism from acrylic and wax to catch the trimmed wire pieces, preventing any swallowing or soft-tissue injury.

Posterior Functional Bite Turbos for Sagittal Correction
Volume 54 : Number 7 : Page 435 : Jul 2021
This Pearl describes the application of functional resin turbos on the upper and lower premolars to help correct a Class II malocclusion. When used in conjunction with fixed appliances and elastics, their effect is similar to that of a Twin Block.

An Efficient and Effective Technique for Uprighting Mesially Erupting Lower Second Molars
Volume 51 : Number 3 : Page 179 : Mar 2017
Orthodontists can never have enough techniques in their armamentaria for uprighting mesioangular lower second molars. In this Pearl, as an alternative to a Halterman appliance, the authors use a beta ...

A Simple Glue-Tray Guide for Precise Miniscrew Insertion
Volume 51 : Number 6 : Page 361 : Jun 2017
This Pearl demonstrates a guide for more accurate insertion of miniscrews, using a transfer tray made from glue as described in an indirect-bonding technique. The simple glue tray provides three-dimensional orientation and stabilizes the manual driver during placement, with the precise location of the miniscrew confirmed by a periapical radiograph.

Root-First Lingual Canine Retraction with Power Arms
Volume 51 : Number 7 : Page 427 : Jul 2017
Uprighting canines is challenging with lingual appliances because of the narrow brackets and short interbracket distances. This Pearl describes a lingual technique that can be effectively employed after premolar extractions, using a special Incognito canine bracket with an auxiliary tube in combination with lingual power arms and palatal mini-implants.

Derotation of an Upper Molar Using Cantilever Mechanics
Volume 56 : Number 8 : Page 483 : Aug 2022
A maxillary first molar sometimes erupts with a mesial-in rotation. This simple cantilever spring is inserted in the molar tube from the distal to rotate a single molar mesial-out, using anchorage from the main archwire on the same side.
