Correction of Anterior Crossbite and an Unesthetic Smile Arc in an Adult Patient
Volume 45 : Number 1 : Page 31 : Jan 2011
Borderline and mild skeletal Class III relationships in adult patients are usually treated by orthodontic camouflage. Reasonably good results have been achieved with nonsurgical treatment of anterior ...

Treatment of Severe Anterior Crowding with the Invisalign G6 First-Premolar Extraction Solution
Volume 53 : Number 8 : Page 459 : Aug 2019
This new system was designed by Align Technology to ensure root parallelism during canine retraction and to maintain vertical control by maximizing posterior anchorage during space closure. A sample case involving four first-premolar extractions is presented by Drs. Zhu, Li, and Lai.

Delayed Extraction of the Mesial First-Molar Root as a Means of Accelerating Space Closure
Volume 53 : Number 8 : Page 470 : Aug 2019
When a lower first permanent molar needs to be extracted, the adjacent second and third molars are often protracted to close the space. Drs. Lee and Park compare two patients to demonstrate how hemisection of the first-molar root can speed up protraction and reduce the risk of alveolar bone atrophy.

Treatment Effects of a Fixed Functional Appliance in Non-Growing Class II Patients
Volume 54 : Number 9 : Page 525 : Sep 2020
The AdvanSync 2 appliance attaches only to the first molars, allowing it to be inserted during the leveling and alignment phase. Its use is demonstrated by Drs. Izhar, Dahiya, Singh, and Goyal in two Class II, division 1 patients in the later stages of growth.

Optical Properties of Seven Types of Clear Aligners Before and After In Vitro Aging
Volume 56 : Number 3 : Page 149 : Mar 2022
Using a spectrophotometer, Dr. Cremonini and colleagues compare the transmittance and absorbance percentages of clear aligner trays from All In, Air Nivol, Arc Angel, Invisalign, F22, and Nuvola before and after aging for 14 days in artificial saliva.

An Efficient Palatal Approach for Correction of Unilateral Skeletal Crossbite and Anterior Open Bite
Volume 56 : Number 4 : Page 221 : Apr 2022
This unilateral mini-implant-assisted rapid palatal expander (MARPE), as described by Drs. Banankhah and Uribe, has an attached tongue crib for open-bite treatment. Palatal temporary anchorage devices are placed on the non-crossbite side to help achieve unilateral skeletal expansion.

Volume 56 : Number 8 : Page 473 : Aug 2022
Dr. Boanger shows how maxillary incisors can be intruded as a block with progressive step-up bends in a sectional wire, using indirect anchorage from buccal mini-implants. The intrusive force produces incisor proclination for arch lengthening, and a buccal root-torquing bend then provides axial control.

An Intrusion Screw System for Miniscrew-Assisted Maxillary Molar Intrusion
Volume 56 : Number 9 : Page 508 : Sep 2022
Intrusion of overerupted molars is difficult to achieve in adult patients with conventional mechanics. Dr. Derton and colleagues use segmental posterior archwires to control torque with skeletal support from three miniscrews: two buccal interradicular and one palatal.

Space Closure with Single Miniscrews in Patients with Upper Lateral-Incisor Agenesis
Volume 57 : Number 2 : Page 20230201 : Feb 2023
Agenesis of the maxillary lateral incisors is a common developmental anomaly, with a prevalence of 1-3%. Caucasians represent about 20% of these cases,1-4 and females seem to be affected more than mal...

Use of 3D Metrology Software to Analyze Aligner Treatment Outcomes after Lower-Incisor Extractions
Volume 57 : Number 12 : Page 747 : Dec 2023
Extraction of a single lower incisor and interproximal reduction can facilitate clear aligner treatment for the relief of severe crowding. Drs. Giulieri, Weir, and Freer use a 3D modeling program to assess the accuracy of such treatment, as compared with the predicted results.

CASE REPORT
Volume 58 : Number 5 : Page 293 : May 2024
In this patient, the third molars are used instead of miniscrews to anchor orthodontic retraction using lingual appliances and Class III elastics. The lower third molars are first mesially sliced to create space for retraction, and eventually are extracted.

Improved Biomechanical Control with Spark Aligner Approver Root-Visualization Software
Volume 58 : Number 8 : Page 466 : Aug 2024
Spark Aligner Approver’s root-visualization feature allows dental root shapes to be considered when planning aligner treatment. Dr. Pinter demonstrates the use of this software to determine whether relative or absolute extrusion of the upper incisors is indicated and to stage the required movements.

Herbst Appliance with Four-Miniscrew Anchorage for Mandibular Advancement after the Pubertal Peak
Volume 58 : Number 8 : Page 505 : Aug 2024
In this article, Drs. Manni, Boggio, Caldara, Gastaldi, and Cozzani treat a 17-year-old patient with a Class II, division 1 malocclusion using a miniscrew-assisted rapid palatal expander, along with a skeletally supported Herbst appliance modified to limit lower-incisor inclination.

Controlled Space Closure with a Preadjusted Appliance System
Volume 24 : Number 4 : Page 0 : Apr 1990
Preadjusted appliances, following the original concept of the Andrews Straight-Wire Appliance,1 became increasingly common in the 1980s. By 1986, they were reportedly used more than twice as much as a...

Thoughts on Stripping of Anterior Teeth
Volume 5 : Number 9 : Page 510 : Sep 1971
