A Removable Acrylic Inclined Plane for Anterior Crossbite Correction
Volume 54 : Number 4 : Page 247 : Apr 2020
This removable appliance is an alternative to a composite bite turbo for nudging an upper permanent incisor out of crossbite during the early mixed dentition. If a lower incisor also needs to be moved, a finger spring can be embedded in the acrylic.

An Esthetic Removable Inclined Plane
Volume 54 : Number 5 : Page 275 : May 2020
An anterior crossbite can be resolved with a fixed inclined biteplane, but those devices have drawbacks in terms of hygiene, speech, and mastication. This removable, vacuformed alternative uses a full dental arch as anchorage to correct a crossbite during Phase I treatment.

Crimpable Hooks to Control Pressure from Forsus Push Rods
Volume 54 : Number 11 : Page 711 : Nov 2020
Constant mesial pressure from the push rod of a Forsus Fatigue Resistant Device can debond the lower bracket and increase treatment time. This Pearl describes a simple archwire hook that can be crimped onto the base archwire to relieve such pressure.

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.

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.

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.
