Orthodontic Traction of Impacted Upper Canines Using the VISTA Technique
Volume 51 : Number 2 : Page 0 : Feb 2017
Upper canines have the longest and most complicated period of tooth development. Because they begin mineralization before the first molars and incisors and take twice as long to completely erupt, they are more susceptible to changes in the normal eruption pathway, leading to the common clinical problem of impaction. The prevalence of impacted upper permanent canines is approximately 1-3% -- more than for any other teeth except the third molars. Palatal impaction is two to three times more common than buccal impaction.

Volume 56 : Number 10 : Page 567 : Oct 2022
The sliding jig presented by Drs. Pithon, Vieira, Souza, and Freitas is designed to move teeth laterally with support from mini-implant anchorage, thus avoiding unwanted side effects. A complex case is shown in which an incisor was moved across the midline.

Class III Correction Using Clear Aligners, Sectional Wires, and Miniscrew Anchorage
Volume 57 : Number 1 : Page 54 : Jan 2023
Dr. Arveda and colleagues demonstrated a technique in which clear aligners are trimmed to allow placement of a partial fixed labial appliance with anchorage from a retromolar miniscrew. A case involving extraction of a single lower incisor illustrates their method.

Measuring Symptom Severity with the TMJ Scale
Volume 25 : Number 1 : Page 0 : Jan 1991
Patients with temporomandibular disorders (TMD) usually seek care in response to specific symptoms. Although pain in the face or head is the most frequent chief complaint,1 a wide variety of symptoms ...

Improving Incisor Torque Control with Nickel Titanium Torque Bars
Volume 33 : Number 4 : Page 224 : Apr 1999
Although rectangular archwires in edgewise bracket slots are an effective means of providing static tooth control, they are an inefficient method of delivering continuous and progressive torquing forc...

The Mini-Distalizing Appliance: The Third Dimension in Maxillary Expansion
Volume 37 : Number 9 : Page 467 : Sep 2003
Since its introduction more than a decade ago, the Pendulum* appliance has undergone numerous changes that have greatly improved patient comfort, ease of placement, stability, and overall treatment re...

Tooth Movement with Essix Mounding
Volume 38 : Number 8 : Page 435 : Aug 2004
The Essix* system of tooth-moving mechanics is based on the philosophy that the orthodontist should have enough control over a case to make in-course corrections at the chair throughout treatment.1-3 ...

Atypical Extractions in Adult Treatment
Volume 49 : Number 5 : Page 312 : May 2015
Adult treatment sometimes dictates an atypical or "strategic" extraction plan, especially in a patient with periodontal problems.1-7 Although the decision to extract a permanent canine with periodonta...

Treatment of Pseudo-Class III Malocclusion with a Modified Reverse Twin Block and Fixed Appliances
Volume 49 : Number 7 : Page 470 : Jul 2015
Pseudo-Class III malocclusion refers to a patient with an anterior functional shift of the mandible resulting from premature contact between lingually inclined maxillary incisors.1-4 Moyers described ...

Multidisciplinary Management of Post-Ankylosis Malocclusion and Mandibular Deformity
Volume 51 : Number 12 : Page 809 : Dec 2017
Ankylosis of the TMJ can lead to severe functional, dental, facial, and esthetic problems that will require a multidisciplinary approach to resolve. The authors present a protocol involving orthodontic alignment and distraction osteogenesis for treatment of adults with long-standing TMJ ankyloses.

THE CUTTING EDGE
Integrating CBCT and Virtual Models for Root Movement with Clear Aligners
Volume 54 : Number 3 : Page 159 : Mar 2020
Dr. D’Alessandro and colleagues describe a 3D data fusion method for creating orthodontic models from optical surface scans and CBCT images. This combined imaging is then used to construct clear aligners with “divots,” providing couples to control root positions in all three planes of space.

"Surgery First" Approach for Obstructive Sleep Apnea Treatment
Volume 56 : Number 1 : Page 34 : Jan 2022
Orthognathic surgery is a reliable solution for more severe cases of sleep apnea. As Dr. Pereira and colleagues illustrate, the “surgery first” approach is appealing to these patients because it enables more rapid relief of OSA symptoms. A typical adult case is shown.

3D-Printed Hybrid Keyless Expander for Maxillary Expansion and Protraction
Volume 59 : Number 3 : Page 180 : Mar 2025
Mr. Keles and Drs. Keles, Kayalar, Ozcan, and Akyalçin introduce a hybrid version of the Keles Keyless Expander that combines their key-free jackscrew with a customizable, metal-printed frame that can be used for the attachment of miniscrews and to support a facemask.

Lower-Molar Distalization with Mini-Implant Anchorage in Asymmetrical Class II Cases
Volume 51 : Number 2 : Page 0 : Feb 2017
About half of all Class II malocclusions are asymmetrical. If the upper molar is mesially displaced, the maxillary midline will deviate toward the Class I side, and treatment will require either extraction of one upper premolar or distal molar movement on the Class II side. In 61% of asymmetrical Class II cases, however, where the lower molar is distally displaced, the maxillary midline will match the medium sagittal plane, but the mandibular midline will deviate toward the Class II side. If the profile is convex, asymmetrical extractions (two upper premolars and one lower premolar on the Class I side) are generally used for correction. Another option is to extract four premolars, but this will extend treatment time.

Congenitally Missing Lateral Incisor Treatment
Volume 19 : Number 4 : Page 258 : Apr 1985
When treating patients with congenitally missing maxillary lateral incisors, the orthodontist must decide whether to close the spaces or open them and place fixed bridges. Several authors have suggest...

Management of Pathological Tooth Migration in Patients with Advanced Periodontal Disease
Volume 47 : Number 9 : Page 520 : Sep 2013
Chronic periodontitis is characterized by a loss of clinical attachment due to destruction of the periodontal ligament and loss of the adjacent supporting bone.1 The condition may be localized, involv...

Correction of Lip Protrusion with Lingual Brackets and Palatal Anchorage
Volume 47 : Number 10 : Page 614 : Oct 2013
Although absolute anchorage is crucial in the treatment of lip protrusion, especially when lingual appliances are used, most skeletal-anchorage devices have disadvantages in such cases. A dental impla...

Spring-Assisted Molar Intrusion in Clear-Aligner Treatment
Volume 51 : Number 5 : Page 270 : May 2017
Although fixed appliances with either continuous or segmented archwires are an effective method of intruding teeth, extrusion of the adjacent anchorage teeth is inevitable in most cases. In recent yea...

Unusual Extraction Combinations in Patients with Impacted Maxillary Canines
Volume 53 : Number 10 : Page 603 : Oct 2019
Surgical removal of an ectopically impacted upper canine and substitution by the first premolar can be an option in suitable adult patients. Dr. Al Shhab and colleagues show how the extraction of a lower first molar with poor prognosis can contribute to successful arch alignment in such a case.
