Diagnosis of Anomalous Teeth with Cone-Beam Computed Tomography
Volume 46 : Number 3 : Page 156 : Mar 2012
Tooth anomalies in the permanent dentition are rare and often incidental findings in routine orthodontic care. Occasionally, however, an anomaly may have a considerable impact on orthodontic treatment...

Generalized Idiopathic External Root Resorption
Volume 27 : Number 9 : Page 0 : Sep 1993
Root resorption is not in itself an unusual finding; a slight amount of root resorption may be present in all secondary teeth.1 Although a patient may complain that a tooth has suddenly loosened, it c...

Mini-Implant for Orthodontic Anchorage
Volume 11 : Number 11 : Page 763 : Nov 1997
Osseointegrated titanium implants have been used successfully to replace missing teeth, but their use for orthodontic anchorage has been limited by space.1-7 Conventional dental implants can only be p...

The Miniplate with Tube for Skeletal Anchorage
Volume 7 : Number 7 : Page 407 : Jul 2002
Anchorage control has always been a difficult and unpredictable challenge for orthodontists.1 Unlike headgear, which relies on patient compliance to achieve tooth movement,2 implants provide true stat...

A New Fixed Interarch Device for Class II Correction
Volume 37 : Number 1 : Page 36 : Jan 2003
Fixed devices are increasingly being used for molar distalization in Class II treatment because they eliminate the need for special patient compliance. These appliances fall into two main categories: ...

Use of Bonded Power Arms in Cases with Missing Upper Lateral Incisors
Volume 38 : Number 10 : Page 539 : Oct 2004
There are two basic options for treating patients with missing maxillary lateral incisors. The first is to close the spaces and substitute the canines for the lateral incisors; the second is to redist...

A Removable Class II Appliance for Simultaneous Distalization and Expansion
Volume 39 : Number 10 : Page 613 : Oct 2005
Treatment of a case of Class II malocclusion with maxillary arch constriction and anterior crowding generally involves expanding the arch, distalizing the molars, and aligning the anterior teeth.1-4 T...

A Space Maintainer for Growing Patients with Avulsed Central Incisors
Volume 46 : Number 1 : Page 27 : Jan 2012
Avulsion of the central incisors is not uncommon in children and adolescents who have experienced dental trauma. Although reimplantation is the ideal treatment, the longer the tooth is out of the alve...

Gradual Grinding of a Talon Cusp During Orthodontic Treatment
Volume 46 : Number 2 : Page 111 : Feb 2012
Dens evaginatus is a developmental aberration of a tooth resulting in formation of an accessory cusp that has been described as an abnormal tubercle, elevation, protuberance, excrescence, extrusion, o...

THE EDITOR'S CORNER
Pushing the Extraction Envelope
Volume 49 : Number 5 : Page 297 : May 2015
It seems that the great extraction debate is an inherent artifact of the specialty of orthodontics. I took up the subject in JCO as recently as December 2014, when Drs. Daniel J. Rinchuse, Lauren Sigl...

The Shoulder Spring for Eruption of Impacted Canines
Volume 51 : Number 10 : Page 657 : Oct 2017
The authors present a simple device for forced eruption of impacted canines without special patient compliance. Unlike previous techniques, it avoids using the lateral incisors for anchorage, reducing the possibility of root resorption and the need for additional palatal root torque.

Correction of Severe Crowding in Teenage Patients Using the Invisalign System
Volume 54 : Number 7 : Page 383 : Jul 2020
A young patient with upper and lower anterior crowding can now be treated without extractions using only clear aligners. Drs. Ojima, Dan, Kumagai, Watanabe, and Nanda demonstrate an approach involving upper arch expansion and molar distalization in a 12-year-old female.

Anatomical Limits for Distalization of Lower Posterior Molars with Micro-Implant Anchorage
Volume 53 : Number 5 : Page 305 : May 2019
Based on conventional lateral cephalograms, the anterior border of the ascending ramus has been considered the limit for lower molar distalization. Drs. Kim, Jang, and Park use computed tomography to provide visual evidence of a more realistic anatomical limit.

A Fixed Labial/Lingual Technique for Rapid Bite Opening
Volume 25 : Number 10 : Page 0 : Oct 1991
Lower incisor brackets are frequently sheared off by biting forces in deep-bite cases with minimal overjet. Previous methods of preventing this bracket loss have involved considerable time and expense...

Effects of First Bicuspid Extractions on Facial Height in High-Angle Cases
Volume 27 : Number 11 : Page 0 : Nov 1993
Some disagreement exists concerning the effect of bicuspid extractions on the vertical dimension. It has been suggested that orthodontic forward movement of the posterior teeth after bicuspid extracti...

Twist Ligation: A Technique to Reduce Archwire Binding
Volume 30 : Number 3 : Page 0 : Mar 1996
Differential anchorage is necessary when sliding mechanics must be applied asymmetrically. There is probably a linear relationship between stress (force per unit area) and tooth movement.1 However, be...

Orthodontic Treatment: Art or Science?
Volume 34 : Number 6 : Page 371 : Jun 2000
Most orthodontists prefer to think of themselves as scientists, and yet much of orthodontic therapy is closer to art than to science. While many aspects of diagnosis, treatment planning, treatment, an...

Molar Distalization with a Modified Distal Jet Appliance
Volume 34 : Number 7 : Page 419 : Jul 2000
The Distal Jet* is a fixed palatal appliance that is most commonly used to distalize the maxillary molars, either unilaterally or bilaterally. Advantages of the Distal Jet include improved esthetics,...
