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.

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 ...

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...

A Multidisciplinary Approach to the Management of Long-Face Syndrome and Bilateral Microtia
Volume 47 : Number 9 : Page 537 : Sep 2013
The term "long-face syndrome" was developed to combine the dental, skeletal, and facial characteristics of patients previously classified under such descriptions as "skeletal open bite", "iidiopathic ...

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...

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.

A Protocol for Torque Selection with Passive Self-Ligating Brackets
Volume 54 : Number 7 : Page 392 : Jul 2020
Drs. Balut, Hernández, Soto, and Pérez recommend positive, negative, or standard torque values to minimize the undesirable side effects of anterior self-ligating brackets in treating various types of Class I, Class II, Class III, and open-bite cases.

Aligner Treatment of Transposed Maxillary Canines and Lateral Incisors
Volume 55 : Number 1 : Page 34 : Jan 2021
Aligner therapy can now be employed to accommodate forced eruption of transposed canines and lateral incisors, using auxiliaries such as elastomeric traction applied directly to the trays. The authors present a typical treatment involving a 13-year-old female patient.

2022 Eugene L. Gottlieb JCO Student of the Year: Dr. Shelby Steffenhagen
Volume 56 : Number 5 : Page 264 : May 2022
A student from the University of Texas Health San Antonio School of Dentistry is named the seventh winner of this award. In a short question-and-answer session, Dr. Steffenhagen tells her story and discusses her views on current orthodontic treatment.

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.

Direct Printing of Clear Aligners
Volume 57 : Number 8 : Page 450 : Aug 2023
As illustrated by Drs. Kim and Graf, a new photocurable clear resin enables direct 3D printing of customized clear aligners. The authors discuss the design of vertical, sagittal, and transverse tooth movements; the use of divots instead of attachments; and the importance of proper aligner fit.

Extrusion of Ankylosed Maxillary First Molars Using a Boneborne Vertical Distractor
Volume 58 : Number 2 : Page 110 : Feb 2024
A vertical periodontal ligament distractor is described by Dr. Schmid-Herrmann and colleagues for use in patients with ankylosed upper first permanent molars. The appliance consists of two Beneplates welded together, an open expansion screw, and a cantilever arm to erupt the ankylosed tooth after luxation.

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.

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...
