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.
