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...
