Volume 55 : Number 5 : Page 210501 : May 2021
This is the first in an online series of case reports from the three finalists for the 2021 JCO Student of the Year Award. Dr. Gross describes her successful treatment of an anterior open bite with dental protrusion and severe crowding.
Volume 48 : Number 1 : Page 0 : Jan 2014
The combination of an open bite with an asymmetrical skeletal Class III malocclusion poses a significant challenge to the orthodontist. Patients with dentofacial deformities often require an interdisc...
Volume 47 : Number 6 : Page 365 : Jun 2013
Unilateral mandibular condylar hyperplasia is a self-limiting, pathological condition causing excessive growth of the affected condyle and significant dentofacial asymmetry, with unfavorable effects o...
Volume 51 : Number 10 : Page 667 : Oct 2017
A young patient with a skeletal Class III malocclusion was successfully treated without surgery after extraction of the lower first molars. Precise mechanics are recommended to achieve optimal force control and long-term stability in such cases.
Volume 32 : Number 5 : Page 293 : May 1998
A dilaceration is a deformity of a tooth due to a disturbance between the unmineralized and mineralized portions of a developing tooth germ.1 The dilaceration, which can occur in either the crown or t...
Volume 32 : Number 7 : Page 417 : Jul 1998
The treatment protocol for patients with complete unilateral clefts of the lip and palate1 (UCLP) in our center at the University of São Paulo, Brazil, includes cheiloplasty, performed after the age o...
Volume 38 : Number 10 : Page 563 : Oct 2004
Osseointegrated implants have been successfully used as alternatives to bridges for replacement of congenitally missing teeth.1-11 Although normal and stable papillae are difficult to obtain between a...
Volume 43 : Number 12 : Page 0 : Dec 2009
The use of skeletal anchorage in orthodontic treatment has increased exponentially in recent years. One advantage of temporary anchorage devices (TADs) is that they apply orthodontic force without dis...
Volume 34 : Number 4 : Page 239 : Apr 2000
High-pull headgear is often used in the treatment of dolichofacial Class II patients because of a force system that can be described as follows: The center of resistance of the first molar is located ...
Volume 57 : Number 9 : Page 537 : Sep 2023
Forced eruption of a transmigrant ectopic canine is performed using a lower lingual holding arch with a cantilever arm. The closed elastic traction is activated distally and labially, away from the roots of the lower incisors, to avoid resorption.
Volume 49 : Number 4 : Page 273 : Apr 2015
The etiology of impaction is multifactorial1; causes may include genetic predisposition, mesiodens or multiple supernumerary teeth in the anterior maxillary region,2,3 odontogenic tumors such as odont...
Volume 52 : Number 4 : Page 227 : Apr 2018
Drs. Manni, Lupini, and Cozzani describe an innovative combination of Class II elastics and temporary anchorage devices. Their treatment takes advantage of the versatility of intermaxillary elastics in producing reliable sagittal and extrusive forces, while avoiding the side effects associated with anchorage loss.
Volume 57 : Number 7 : Page 419 : Jul 2022
In this camouflage treatment, the authors achieved clockwise rotation of the occlusal plane with a Forsus appliance and indirect anchorage from three maxillary miniscrews. Lower-incisor proclination was controlled by using negative-torque brackets and adding lingual crown torque to the archwire.

Various extraoral and intraoral fixed appliances have been used in Class II cases to distalize the upper molars without extractions. The main disadvantage of these appliances is anchorage loss, which may cause mesial tipping of the anterior teeth unless skeletal anchorage is added. There is also some controversy regarding the effectiveness of distalizing appliances once the second and third molars have erupted. This case report describes the use of heat-activated nickel titanium wires for molar distalization, referred to as the Loca-System, to correct a Class II malocclusion with skeletal asymmetry.
Volume 57 : Number 1 : Page 63 : Jan 2023
This adult patient presented with an ectopic upper left canine and an impacted upper right canine. After traction of the impacted canine with a cantilever spring and miniscrew anchorage, the case is completed with two stages of clear aligner therapy.
Volume 44 : Number 5 : Page 313 : May 2010
The frequency of second-molar impaction is reportedly only .08% in the maxilla and .01% in the mandible.1 When a second molar requires extraction because of ankylosis or unfavorable positioning, the t...
Volume 51 : Number 6 : Page 353 : Jun 2017
This case of an adult patient with bimaxillary protrusion is complicated by the need to extract posterior teeth due to extensive caries. Skeletally anchored molar protraction allows asymmetrical mechanics to be used for extraction space closure, making the authors’ technique a potential alternative to prosthetic restoration of the edentulous areas.
Volume 45 : Number 8 : Page 453 : Aug 2011
Whatever treatment method is used for maximum bodily retraction in extraction cases, the clinician's ability to control the mechanics will determine the outcome. One of the inherent limitations of ort...
Volume 55 : Number 10 : Page 617 : Oct 2021
Few studies have documented the use of clear aligners as an alternative to fixed appliances in extraction cases requiring substantial mandibular molar movement. This report demonstrates the use of Invisalign G6 attachments and Power Ridges in an adolescent patient.
Volume 8 : Number 8 : Page 423 : Aug 2003
Conventional methods of controlling molar eruption in patients with vertical maxillary excess, such as high-pull headgear,1,2 vertical chin cups,2,3 and removable and fixed appliances,4,5 cannot effec...
