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.

Improving the Bond Strength of Molar Tubes
Volume 56 : Number 10 : Page 595 : Oct 2022
This month’s Pearl shows how adding a small amount of composite over the occlusal portion of a molar tube can increase the surface area of the base and thus deflect force and enhance bond strength, preventing bond failures.

Indirect Rebonding Transfer Tray Following Magnetic Resonance Imaging
Volume 57 : Number 6 : Page 359 : Jun 2023
When a patient needs to have fixed appliances removed for an MRI, a single intraoral scan can be used to produce both a temporary Essex retainer and an indirect transfer tray, allowing the brackets to be replaced in the same positions.

The Piston Elastic for Uprighting an Ectopic Molar
Volume 57 : Number 7 : Page 407 : Jul 2023
Early correction of a mesio-angulated first permanent molar is crucial to avoid root resorption of the second deciduous molar. In this simple Pearl, a stiff wire segment pushes off the deciduous molar to distalize the permanent molar.

A Mini-Implant-Supported Canine Cantilever Spring
Volume 57 : Number 8 : Page 479 : Aug 2023
Early extrusion of a palatally impacted upper canine is enabled by a skeletally anchored cantilever arm. Two bracket-head miniscrews are inserted with their slots aligned for proper torque expression. The canine can be erupted within six months, independent of the adjacent teeth.

Effective Isolation and Bonding of Mandibular Second Molars
Volume 58 : Number 2 : Page 117 : Feb 2024
In this Pearl, Dr. Jarosz connects a saliva ejector to a cheek-and-tongue retractor to provide buccal and lingual isolation for bonding lower second molars. Bite turbos on the adjacent first molars prevent debonding of the molar tubes.

Correction of Occlusal-Plane Cant Using Spee-Anti-Spee Wires
Volume 58 : Number 5 : Page 289 : May 2024
A canted occlusal plane is a challenging problem that can affect facial esthetics. In this Pearl, after initial leveling and alignment, rectangular TMA archwires are configured with Spee and anti-Spee bends on opposite sides to compensate for the cant.

Customized Metal-Printed Appliance for Molar Derotation and Distalization
Volume 58 : Number 6 : Page 377 : Jun 2024
This Pearl illustrates a completely digital workflow in which computer-aided design and selective laser melting are used to print a customized appliance that can accomplish the challenging movements of upper first-molar derotation and distalization with ample anchorage.

Multiloop Surgical Archwire as an Alternative to Crimpable Lugs
Volume 58 : Number 12 : Page 775 : Dec 2024
In this Pearl, the authors present an alternative to using crimpable lugs on a surgical archwire for the attachment of heavy intermaxillary elastics. Bending an archwire with multiple interbracket loops eliminates the potential for detachment or lip irritation.

Use of Elastomeric Chain and Open-Coil Spring to Correct a Severely Rotated Premolar
Volume 59 : Number 2 : Page 107 : Feb 2025
To simplify the derotation of a severely rotated premolar, this Pearl introduces a technique involving the use of an elastomeric chain to compress an open-coil spring to one-third of its length, enabling the spring to exert a distal force on the posterior end of the chain.

Inverted Elastomeric Ligatures with Guards for Lower-Lip Hypertonicity
Volume 59 : Number 4 : Page 249 : Apr 2024
A hypertonic lower lip can press forcefully against the lower brackets, causing painful indentations in the mucosa. As a solution, this Pearl describes how to use upside-down elastomeric ligatures with guards to protect the soft tissue like a lip bumper.

Attachment Beauty Queen: The "Sash" for Rotation Correction of Upper Lateral Incisors
Volume 50 : Number 3 : Page 0 : Mar 2016
One the most challenging movements to make with is rotation correction of the upper lateral incisors. Conventional attachments are often unable to prevent the aligner from slipping off the facial surface of the tooth. In this Pearl, Invisalign expert Dr. Jonathan Nicozisis describes his "sash" attachment design. Having used it numerous times, I promise it will become your favorite technique for controlling stubborn malrotated lateral incisors. NEAL D. KRAVITZ, DMD, MS, Associate Editor for Pearls

Phase I Retainer with Pontics for Ectopic Canines
Volume 59 : Number 1 : Page 65 : Jan 2025
Treatment of palatally displaced canines may require Phase I expansion and removal of the anterior deciduous teeth, but many children are reluctant to proceed with the extractions. This Pearl describes a Phase I retainer with pontics that can be used to resolve their concerns.

Double Traction for Lower- First-Molar Space Closure
Volume 50 : Number 2 : Page 118 : Feb 2016
Protraction of a lower molar through an edentulous space is particularly challenging. Archwire bends alone are often unable to prevent tipping and rotation of the molar. This Pearl offers a simple technique that provides lingual support during lower-molar protraction, thus improving the efficiency of space closure and avoiding unwanted tooth movement. NEAL D. KRAVITZ, DMD, MS Associate Editor for Pearls
