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.

Volume 56 : Number 11 : Page 649 : Nov 2022
Any vulnerable segment of a flexible archwire can be protected with a made-to-measure section of rigid stainless steel tubing. This Pearl can thus avoid archwire breakage and consequent emergencies, while also improving comfort for the patient’s buccal mucosa.

Cross-Arch Elastics for Tongue Isolation in Bonding Lower Lingual Retainers
Volume 56 : Number 12 : Page 737 : Dec 2022
Proper isolation is the most important concern in bonding a lower lingual retainer, but can sometimes be difficult to achieve with standard retractors. This simple Pearl uses cross-arch elastics to trap the tongue, thus ensuring an open field for the procedure.

CAD/CAM Sheath for Attaching a Cantilever Spring to a Metal-Printed Rapid Palatal Expander
Volume 87 : Number 2 : Page 119 : Feb 2023
Although metal-printed expanders have become increasingly popular, their rigid framework is a disadvantage. This digitally designed sheath is printed into the metal frame to enable simultaneous traction of an impacted canine with an adjustable beta titanium cantilever spring.

Lingual Step-In Bend for Use with Piggyback Mechanics
Volume 57 : Number 4 : Page 248 : Apr 2023
An impacted canine is often extruded with a nickel titanium piggyback wire. A vertical bend in the base archwire will avoid interference with the erupting tooth; if the canine is in the lower arch, an additional lingual bend avoids contact with the opposing teeth.

Open-Coil Activation of Impacted Canines
Volume 57 : Number 10 : Page 625 : Oct 2023
A superelastic open-coil spring and power thread are employed to erupt an ectopic maxillary canine in a controlled direction. The elastic thread is tied to the distal end of the compressed coil spring, and as the spring opens, the canine is activated vertically and distally.

A Modified Bracket Position for a Rotated Tooth
Volume 57 : Number 11 : Page 644 : Nov 2023
Horizontal or vertical positioning of a bracket on the tooth surface will affect the final alignment of that tooth. This Pearl illustrates how to place a central-incisor bracket on the mesial aspect to promote mesial-out rotation during initial alignment.

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.

Bonding Attachments Directly to Teeth
Volume 3 : Number 8 : Page 399 : Aug 1969
The placement of orthodontic attachments (buttons, hooks, and other attachments) directly to the teeth without the necessity of fabricating bands has long been the orthodontist's dream. For the past t...

Volume 55 : Number 10 : Page 627 : Oct 2021
These acrylic bite turbos rest on the occlusal surfaces of the molars and connect to the lingual sheaths on the molar bands. As the authors illustrate, they can easily be inserted and removed by the clinician at the chair.

Early Derotation of Palatally Impacted Canines
Volume 57 : Number 12 : Page 759 : Dec 2023
After open exposure of a palatally impacted canine, the tooth will erupt medially, but occasionally will also be malrotated. This Pearl reviews the use of buccal and lingual buttons and elastic chains to derotate the canine while moving it into the arch.

A Windowed Temporary Crown for a Peg-Shaped Lateral Incisor
Volume 52 : Number 10 : Page 559 : Oct 2018
Spaces created prior to restoration of a peg-shaped lateral incisor are traditionally maintained with closed-coil springs. This Pearl shows an esthetic alternative: a temporary crown with a window that allows a bracket to remain bonded to the incisor surface during retraction and space closure.

Mini-Implants as Bone Maintainers
Volume 53 : Number 8 : Page 479 : Aug 2019
Vertically positioned miniscrews with pontics have long been used for tooth replacement in adolescent patients. This Pearl offers a variation of that technique, describing the insertion of a horizontal miniscrew beneath a Maryland bridge to halt the progression of alveolar ridge atrophy.

A Crimpable Stopper for Tooth Rotation
Volume 54 : Number 6 : Page 369 : Jun 2020
Bonding a bracket to a severely rotated tooth is difficult because of the lack of space. Dr. Masters proposes a crimpable archwire stopper as an alternative to a bonded eyelet for derotating a lower canine, as demonstrated in an adult patient.
