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.

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

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

Double-Ligation Technique for Rotated Teeth
Volume 50 : Number 4 : Page 258 : Apr 2016
Ligating a rotated tooth with a stainless steel wire is particularly difficult. The goal is to place the pigtail on the most rotated side to fully seat the wire into the bracket slot, but the problem ...

Measuring Bonded Lingual Retainers
Volume 51 : Number 5 : Page 294 : May 2017
Multistranded lingual retainers are commonly “eyeball” measured for length during bonding, which can result in a retainer that is too long or too short. The time needed to cut a new retainer wire exte...

Extraction of Gingivally Retained Deciduous Teeth Using Orthodontic Elastics
Volume 51 : Number 8 : Page 480 : Aug 2017
The authors provide a creative method for loosening a retained deciduous tooth by placing an orthodontic elastic around its cementoenamel junction. The deciduous tooth is simply “squeezed” loose from its gingival attachment in a few days, with no discomfort and minimal bleeding. This technique works for small or large retained teeth.

Forsus Reactivation with Composite Beads
Volume 51 : Number 10 : Page 677 : Oct 2017
The Forsus Fatigue Resistant Device commonly requires the addition of crimpable metal shims to the push-rods for reactivation. This Pearl shows how composite beads can serve as a simple alternative to the shims, using materials readily available in the office.

Remote Retainer Fabrication Using Teledentistry
Volume 51 : Number 11 : Page 706 : Nov 2017
The author details how a replacement retainer was prescribed by an office in Virginia for a patient attending a wedding in Arizona, using digital scanning and teledentistry. The same technique can be applied to a distant Invisalign patient who is in need of refinement aligners.

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.
