PEARLS
The Hybrid Aligner Approach for Extrusion and Rotation of Posterior Teeth
Volume 55 : Number 1 : Page 69 : Jan 2021
Partially erupted upper second molars are difficult to correct with clear aligners alone. This Pearl shows how posterior fixed appliance segments can be used in conjunction with aligners to derotate the second molars and promote posterior occlusion and settling.

A Multipurpose Auxiliary for Intrusion or Retraction with Infrazygomatic Crest Screws
Volume 55 : Number 11 : Page 697 : Nov 2021
When a miniscrew is inserted in its ideal orientation in the infrazygomatic crest, an elastomeric chain tends to slip off. This Pearl shows how to fabricate a simple hook from stainless steel wire for attachment of a chain or a nickel titanium coil spring.

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.

PEARLS
Volume 56 : Number 9 : Page 535 : Sep 2022
Rapid maxillary expansion sometimes produces an unwanted unilateral buccal crossbite. This Pearl uses functional turbos bonded to the lower molars to keep the mandible centered during palatal expansion, thus avoiding the development of a skeletal asymmetry.

Molar Protraction Tube with Multiple Hooks
Volume 57 : Number 3 : Page 187 : Mar 2023
The MP-Tube utilizes a long buccal hook with four steps to apply the protraction force closer to the center of resistance of the molars. Specifications of the tube are included, and the technique is demonstrated in a typical case.

Skeletally Anchored Running-Loop Technique for Mandibular First-Molar Uprighting
Volume 57 : Number 5 : Page 287 : May 2023
Agenesis or loss of a lower second premolar can lead to mesial tipping of the adjacent first molar. This Pearl describes a running-loop spring, supported by indirect miniscrew anchorage and posterior fixed appliances, that can upright and intrude the first molar without side effects.

Second-Molar Crossbite Correction with a Hairpin-Spring Appliance
Volume 50 : Number 5 : Page 0 : May 2016
Lower second molars commonly erupt into a lingual crossbite or "scissor bite". Traditional treatment involves banding or bonding a lingual attachment and running crossbite elastics to the upper second molars, but that method is cumbersome and dependent on patient compliance. This month's Pearl describes a hairpin-spring appliance that can efficiently correct a second-molar crossbite without the need for brackets or elastics.

A Modified Retainer for Class II or III Functional and Surgical Patients
Volume 51 : Number 4 : Page 229 : Apr 2017
Retainers that control anteroposterior correction after orthodontic treatment, such as a bionator or Damon* splint, are often challenging for patients to wear because they restrict mobility. This Pear...

THE EDITOR'S CORNER
Volume 51 : Number 5 : Page 257 : May 2017
Like almost every U.S. orthodontist, JCO maintains a Facebook page as one means of connecting with its customer base—in your case, patients; in ours, readers. The format doesn’t necessarily lend itself to dispensing clinical information, although we have recently begun posting helpful videos related to our published Pearls. We tend to get the most likes and shares from our monthly profiles of finalists for the Eugene L. Gottlieb JCO Student of the Year Award (the most recent winner was announced in the March 2017 issue), no doubt because of these students’ extended networks of relatives and colleagues. But the 50th-anniversary year of the journal has brought us an opportunity for a new and unique Facebook venture.

Efficient Correction of a Rotated Premolar with an Occlusal Tube
Volume 54 : Number 9 : Page 559 : Sep 2020
This simple alternative to buccal and lingual buttons and elastic chains involves placing a molar tube on the occlusal surface of the rotated premolar and inserting a continuous nickel titanium archwire. Procedures for placement and removal are described.

Flexible Bite Turbos for Lingual Appliances
Volume 54 : Number 10 : Page 631 : Oct 2020
This Pearl shows how to make temporary anterior bite turbos from a light-cured composite resin with high elasticity, which can be applied directly over the brackets to prevent occlusal interference. The technique is especially useful with customized lingual appliances such as InBrace.

Lateral Incisor Bracket Positioning for Phase I Treatment
Volume 55 : Number 4 : Page 227 : Apr 2021
This month’s Pearl shows how to modify bracket positioning on the upper lateral incisors during Phase I treatment to avoid premature distal root tip in the path of the erupting canines, thus preventing the development of an unsightly midline diastema.
