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

An Innovative Tucker for the SmartClip System
Volume 50 : Number 8 : Page 503 : Aug 2016
Orthodontists commonly repurpose worn ligature cutters into debonding pliers. This Pearl describes a creative method for modifying a bracket tweezer into an instrument that can be used to seat the arc...

An Easy Activation Technique for a Twin Block Appliance
Volume 50 : Number 10 : Page 620 : Oct 2016
In the absence of maxillary advancement screws, reactivation of a Twin Block appliance often requires the cumbersome and time-consuming addition of acrylic to the maxillary component. This Pearl highl...

Effective Derotation of Canines and Premolars
Volume 50 : Number 11 : Page 700 : Nov 2016
Canines and premolars often erupt in malrotated positions, making proper bracket placement and wire engagement challenging. This Pearl describes the use of buccal and lingual buttons with segmented el...

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.

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.

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.
