Putty Pack for Prevention of Soft-Tissue Overgrowth Around Surgical Miniplates
Volume 49 : Number 8 : Page 516 : Aug 2015
One of the main reasons why clinicians tend to prefer miniscrews over miniplates for skeletal anchorage is the development of soft-tissue overgrowth around miniplate insertion sites, due to chronic ir...

Esthetic Provisional Restoration after Space Closure in Patients with Missing Upper Lateral Incisors
Volume 50 : Number 6 : Page 0 : Jun 2016
Orthodontic space closure in a patient with a missing upper lateral incisor requires a mesial shift that will bring the canine and first premolar into esthetic focus. Additive or subtractive restorative measures such as odontoplasty or enamel reduction will then be needed to alter the visible tooth surfaces. Many cases require individualized adaptation of tooth shapes and colors.

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.

Relapse Correction Using a Modified Spring Aligner and Expansion Screw
Volume 53 : Number 6 : Page 334 : Jun 2019
The authors describe a simple modification to a lower retainer, using a 7mm anteroposterior jackscrew, that can alleviate moderate lower anterior crowding due to relapse. The expansion screw not only provides substantial activation, but is easy to fit and insert.

Etching Mask for Invisalign Attachments
Volume 54 : Number 3 : Page 173 : Mar 2020
A duplicate attachment template tray is ordered from Align Technology and then modified with a scalpel to remove the composite wells. The modified tray is used as a mask to control etchant placement and thus limit the amount of flash, simplifying the bonding appointment.

A Modified Pontic Appliance for Treatment of Impacted Maxillary Canines
Volume 55 : Number 8 : Page 460 : Aug 2021
A patient with an impacted upper canine and retained predecessor may be reluctant to have the deciduous tooth extracted because of the resulting unesthetic edentulous space. Drs. Harrison and Park describe a versatile pontic appliance that can be used for temporary camouflage.

Combination of Clear Aligners and Beneslider for Correction of Severe Midline Deviation
Volume 55 : Number 11 : Page 675 : Nov 2021
Drs. Wilmes, Schwarze, Vasudavan, and Drescher show how unilateral upper molar distalization can correct a Class II subdivision malocclusion, using a palatally anchored device to prevent anchorage loss during clear aligner therapy. A typical adult case illustrates the technique.

Uprighting Mandibular Second Molars with Twin Brackets
Volume 57 : Number 2 : Page 121 : Feb 2023
To upright an impacted second molar, an open-coil spring is commonly placed between the first- and second-molar tubes. This Pearl shows how a twin second-premolar bracket can be substituted for the first-molar tube to improve access for placement of the 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.

CASE REPORT
Volume 57 : Number 7 : Page 397 : Jul 2023
In cleft patients, a maxillary transverse deficiency is often more pronounced in the anterior region. A report of a skeletal Class III case shows how a banded fan-type palatal expander can promote differential expansion and avoid unwanted posterior side effects.

Selective Bracket Bonding for Correction of Mesial Rotations
Volume 57 : Number 9 : Page 511 : Sep 2023
In this Pearl, a relatively well-aligned tooth is initially left unbracketed to allow placement of an open-coil nickel titanium spring that can rotate two adjacent crowded teeth in opposite directions. An example demonstrates quick resolution of a patient’s anterior crowding.

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.
