A "Renewable" Archwire for Uprighting Impacted Lower Second Molars
Volume 50 : Number 4 : Page 0 : Apr 2016
An impacted lower second molar is relatively rare, with an incidence of .06-.3%, but when encountered can be the most challenging problem in an otherwise routine orthodontic treatment. Uprighting usually needs to be done as quickly as possible to restore chewing function, placing a premium on efficient mechanics. Unfortunately, since treatment commonly involves individual manipulation of bracket positions, frequent wire changes or bending, or placement of auxiliaries, an impacted lower second molar is difficult to correct with pre-programmed orthodontic appliances such as Invisalign, SureSmile, or Incognito.

Changes in the Condyle-Fossa Relationship in Patients with TMD after Occlusal Deprogramming
Volume 51 : Number 1 : Page 0 : Jan 2017
Common signs and symptoms of TMD include masticatory muscle pain, TMJ sounds, limited mouth opening, and deviations in mandibular movements. Treatment generally involves some combination of occlusal splints, physiotherapy, relaxation therapy, pharmacological intervention, arthroscopic surgery, education, and behavioral counseling. One randomized controlled trial indicated that an occlusal deprogramming splint is more effective than other methods in treating TMD, although another study produced contradictory results.

CASE REPORT
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.

CASE REPORT
Volume 51 : Number 7 : Page 419 : Jul 2017
A nonextraction approach is demonstrated in an adult high-angle patient with a skeletal Class malocclusion and severe crowding. By using low-friction, passive self-ligating brackets and bilateral temporary anchorage devices over 18 months of treatment, the authors are able to avoid any surgical intervention other than an advancement genioplasty.

Physiological Drifting of Ectopic Canines
Volume 51 : Number 8 : Page 481 : Aug 2017
If first premolars are extracted to make space for ectopic canines, rather than using loop or continuous-arch mechanics, the canines can be allowed to migrate naturally into the extraction sites. Two cases demonstrating this physiological drift are shown, and benefits of the approach are described.

A New Appliance for Efficient Molar Distalization
Volume 51 : Number 11 : Page 738 : Nov 2017
The Molar Thruster consists of a palatal acrylic covering with embedded Begg tubes, which are connected by bayonet wires to the palatal first-molar sheaths. Nickel titanium open-coil springs are compressed over the bayonet wires to deliver the distalizing force during the first phase of treatment.

Miniscrew Anchorage for Posterior Crossbite Correction in an Adult Patient
Volume 52 : Number 3 : Page 165 : Mar 2018
Drs. de Brito, Simões, and Machado resolve a unilateral posterior crossbite and lower anterior crowding in only 15 months. Buccal and palatal miniscrews are used initially to anchor elastic chain for molar intrusion. After leveling with fixed appliances, intermaxillary elastics are added to extrude the molars into occlusion.

Asymmetrical First Molar Extractions
Volume 53 : Number 2 : Page 107 : Feb 2019
Asymmetrical extractions can be a viable option in extraction cases with asymmetrical structural impairment of the first permanent molars. In this 22-year-old patient, the left first molars were extracted along with the right first premolars.

A Zygomatic Miniplate as Skeletal Anchorage for Correction of Severe Skeletal Anterior Open Bite
Volume 54 : Number 4 : Page 221 : Apr 2020
An adult patient presents with a severe anterior open bite of skeletal origin. Avoiding orthognathic surgery, the treatment plan involves upper posterior intrusion and upper anterior retraction, with zygomatic miniplates inserted in the upper quadrants for skeletal anchorage.

A Three-Stage Approach for Managing Impacted Maxillary Incisors in the Mixed Dentition
Volume 56 : Number 6 : Page 334 : Jun 2022
Drs. Greco, Pacifico, and Rombolà demonstrate a technique for recovering impacted incisors in early orthodontic treatment. Rapid maxillary expansion is followed by placement of a palatal arch for de-impaction and a fixed sectional appliance for refinement of the incisor positions.
