Eruption Control of Maxillary Second Molars with a Segmental Overlay Wire
Volume 46 : Number 1 : Page 45 : Jan 2012
Eruption of maxillary second molars at the end of fixed-appliance treatment can be difficult to manage once a rectangular stainless steel archwire has been placed (Fig. 1). A buccally erupting second ...

CLINICAL AID
A Self-Secured Spring Separator
Volume 46 : Number 12 : Page 747 : Dec 2012
Although molar banding remains an important aspect of fixed orthodontic treatment, placement of a thick metal band without proper tooth separation can lead to contraction of the alveolar bone, hyalini...

Immediate Pontic Fabrication Using Flowable Resin
Volume 50 : Number 3 : Page 0 : Mar 2016
In 2006, I described a technique for creating a chairside pontic by taking a bite-registration impression of the patient's adjacent or contralateral tooth. The method was presented as an alternative to reshaping a prefabricated denture tooth, which might not be readily available in an orthodontic office. This article describes another option for immediate chairside pontic fabrication, using flowable resin and a mixing pad.

CASE REPORT
Resolution of a Complex Malocclusion Using a Hybrid Aligner Approach
Volume 55 : Number 6 : Page 343 : Jun 2021
This adult patient was treated with sectional fixed appliances, miniscrew anchorage, and criss-cross elastics during the refinement stage, after clear aligners alone were unable to correct a unilateral posterior scissor bite.

A Digitally Planned Tandem Skeletal Expander and Hybrid Aligner Approach
Volume 57 : Number 1 : Page 32 : Jan 2023
This article describes a two-phase approach for treatment of transverse maxillary deficiency in adult patients, involving an initial stage of maxillary expansion with the Tandem Skeletal Expander followed by an orthodontic stage using clear aligner therapy. A typical case is presented.

Volume 57 : Number 9 : Page 512 : Sep 2023
The posterior lingual cortex of the mandible has been considered the anatomical limit for orthodontic distalization. Drs. Kim and Park show a case in which CBCT images indicate long-term alveolar bone recovery after cortical dehiscence caused by substantial distal movement.

CASE REPORT
Volume 58 : Number 4 : Page 20240401 : Apr 2024
This 17-year-old Class III patient showed signs of primary failure of eruption, but had no family history and tested negative for PTH1R mutations. Successful orthodontic treatment involved a banded expander followed by mandibular distalization using fixed appliances and skeletal anchorage.

ALIGNER CORNER
Volume 58 : Number 9 : Page 540 : Sep 2024
In this edition of the Aligner Corner, the authors outline a hybrid approach to deep-bite treatment that combines aligners not only with attachments, but also with conventional orthodontic appliances such as mini-implants, buttons, and elastics.

Retraction of Bicuspids into Edentulous Spaces
Volume 31 : Number 10 : Page 703 : Oct 1997
Retraction of first and second bicuspids into edentulous spaces can make a fixed restoration a feasible alternative to a distal-extension removable partial denture (RPD). Many patients do not wear par...

CASE REPORT
Use of SPEED Supercable with Sectional Mechanics
Volume 32 : Number 4 : Page 227 : Apr 1998
A maxillary permanent central incisor can fail to erupt because of a midline supernumerary or a retained deciduous incisor. When spontaneous eruption of the permanent incisor does not occur after remo...

Maxillary Molar Intrusion with the Molar Intrusion Arch
Volume 34 : Number 2 : Page 90 : Feb 2000
We have developed a new appliance for maxillary molar intrusion, the Molar Intrusion Arch (MIA), as shown in this article. Appliance Construction and Placement The most critical factor in the intrusi...

Combined Fixed-Functional Treatment of a Class II, Division 2 Malocclusion
Volume 35 : Number 9 : Page 581 : Sep 2001
An 11-year-old male presented with a bilateral dental and skeletal Class II relationship (with the mandible about 7mm retrognathic), combined with a complete anterior deep bite (Fig. 1). The patient's...

A Bite Orthotic for the Resting Period Between Two Phases of Treatment
Volume 36 : Number 2 : Page 92 : Feb 2002
Many skeletal Class II malocclusions are now treated during the mixed dentition, using such "non-compliance" systems as the Herbst* appliance, the MARA**, SAIF Springs***, or the Eureka Spring†. These...

Jumbo Separators for Partial Molar Impactions
Volume 37 : Number 1 : Page 33 : Jan 2003
Partial impactions of erupting permanent molars do not occur often, but when they do, they can cause long-term problems such as disruption of the occlusal plane, damage to abutment teeth, and creation...

Clinical Study of the Effect of No Prophylaxis and Reduced Etching Time on Bond Strength
Volume 37 : Number 2 : Page 99 : Feb 2003
The purpose of the present study was to compare a bonding method of tooth preparation using no pumice prophylaxis and reduced acid etching time to the more traditional method in vivo. In a previous in...

Clinical Management of Unilaterally Impacted Mandibular First and Second Molars
Volume 37 : Number 3 : Page 162 : Mar 2003
Orthodontic traction of impacted teeth can present mechanical challenges, especially when impacted molars are involved. Tooth impaction is uncommon, however, with an overall incidence of between 5.6% ...

Volume 16 : Number 11 : Page 745 : Nov 1982
Classical serial extraction procedures, especially if they include early removal of first bicuspids, and classical theory with regard to "E space" and mesial movement of molars are contrary both to my...

Clinical Effectiveness and Efficiency of Customized vs. Conventional Preadjusted Bracket Systems
Volume 47 : Number 4 : Page 261 : Apr 2013
The ideal bracket system would allow orthodontists to provide high-quality treatment in less time, with fewer appointments and reduced chair-time. Attempts to devise such a system began with Andrews's...
