Facemask Treatment With and Without Maxillary Expansion in Dizygotic Twins

Volume 55 : Number 2 : Page 107 : Feb 2021

Simultaneous interceptive treatment was performed in these twin sisters with Class III malocclusions and anterior crossbites. Facemasks and removable intraoral appliances were used in both, but slow maxillary expansion was added in only one twin. The authors compare the results.



Open-Coil Mousetrap for Labially Impacted Canine Recovery

Volume 58 : Number 3 : Page 169 : Mar 2024

The authors use a closed surgical “tunnel” technique with a “mousetrap” loop and additional open-coil springs to promote vertical eruption of an impacted maxillary canine. Their technique is designed to mimic spontaneous eruption and provide more natural gingival relationships.



Comprehensive Treatment of Severe Cleft Lip and Palate

Volume 53 : Number 6 : Page 357 : Jun 2019

Drs. Ribeiro, Lurentt, Pary, and Suedam detail the treatment of an adult female who had undergone surgery for cleft lip and palate as a child, but had not received clinical care during craniofacial growth. Orthodontic expansion is followed by orthognathic surgery, bone grafting, and secondary plastic surgeries.



Buccal Corridor Changes for Improvement of Smile Esthetics

Volume 54 : Number 2 : Page 111 : Feb 2020

As observed by Dr. Moura and colleagues in this case, the possibility of dentoalveolar expansion with fixed appliances should be considered when correcting a transverse deficiency, because it may also narrow the buccal corridors without surgical or orthopedic intervention.



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.



Management of Alveolar Bone Exostosis after Orthodontic Treatment

Volume 55 : Number 4 : Page 210401 : Apr 2021

This patient developed upper and lower buccal alveolar bone exostoses after premolar extractions and anterior retraction. The upper bony protuberance is removed with minor osseous surgery, and post-treatment follow-up shows normal healing and good orthodontic results.



Orthodontic Eruption of an Impacted and Dilacerated Maxillary Central Incisor

Volume 54 : Number 12 : Page 201201 : Dec 2020

Impacted upper incisors in the early mixed dentition are challenging to treat, especially when associated with dilaceration. This case is managed by orthodontic space opening, followed by traction of the impacted incisor into the arch and then conventional four-second-premolar extraction treatment.



Correction of Unilateral Complete Buccal Crossbite with Miniscrew Anchorage

Volume 50 : Number 8 : Page 0 : Aug 2016

Complete buccal crossbite, which can be a challenging malocclusion to treat, has a prevalence of 1-1.5%.1 A patient with a unilateral complete buccal crossbite involving several teeth typically displa...



Open-Bite Treatment with Aligners and Selective Posterior Intrusion

Volume 53 : Number 1 : Page 39 : Jan 2019

Drs. Dayan, Aliaga-Del Castillo, and Janson describe a method of selective posterior intrusion for correction of anterior open bite using only clear aligners. This 31-year-old Class III patient was treated in 18 months without temporary anchorage devices or elastics.



Nonsurgical Treatment of a Severe Skeletal Anterior Open Bite

Volume 51 : Number 2 : Page 0 : Feb 2017

The etiology of anterior open bite is generally multifactorial, involving a combination of skeletal, dental, and functional effects. Potential causes have been listed as unfavorable growth patterns, digit-sucking habits, enlarged lymphatic tissue, heredity, and oral functional matrices. The most common characteristics of anterior open bite are incisor protrusion and overeruption, but other features may include excessive gonial, mandibular, and occlusal plane angles; a short mandibular body and ramus; excessive lower anterior facial height; reduced lower posterior facial height and upper anterior facial height; a retrusive mandible; a Class II tendency; divergent cephalometric planes; a steep anterior cranial base; and inadequate lip seal. Some studies have found a correlation between a weak orofacial musculature and a long face and consequent anterior open bite.



Surgical-Orthodontic Correction of Long-Face Syndrome

Volume 40 : Number 5 : Page 0 : May 2006

Long-face syndrome is a vertical facial dysplasia that can be associated with various anteroposterior dental relationships, but is most commonly related to a Class II skeletal discrepancy.1-4 The chie...



Nonextraction Treatment of Ectopic Maxillary Canines

Volume 56 : Number 5 : Page 20220501 : May 2022

The 2022 JCO Student of the Year details her diagnosis and treatment planning for a 15-year-old patient with a complicated Class II malocclusion, including ectopically erupting upper canines and a retained upper deciduous canine. Post-treatment results are analyzed with an eye toward potential future improvements.



Reverse Engineering for Post-Treatment Analysis of a Surgical-Orthodontic Case

Volume 56 : Number 10 : Page 20221001 : Oct 2022

An adult Class II patient with a hyperdivergent profile is treated with four premolar extractions, orthodontics, and bimaxillary osteotomies. Fifteen years later, a virtual simulation compares the results with those that could have been achieved with no extractions or two premolar extractions.



Crossbite Correction with Copper Ni-Ti Archwires and Lingual Brackets

Volume 30 : Number 2 : Page 0 : Feb 1996

Treatment of a single-tooth anterior crossbite can be a challenge for the clinician. If the tooth is in deep overbite, a bite plate is often used to avoid interference from the opposing arch. However,...



Complex Surgical-Orthodontic Case with a Transposed Cuspid and Mandibular Asymmetry

Volume 33 : Number 2 : Page 75 : Feb 1999

The following case report shows a patient with a transposed maxillary right first bicuspid and canine who was successfully treated with combined orthodontic and surgical therapy. Shortly after removal...



One-Appointment Correction of a Scissor Bite with 2D Lingual Brackets and Fiber-Reinforced Composites

Volume 40 : Number 7 : Page 0 : Jul 2006

This article describes a quick and simple method to correct a scissor bite using 2D lingual brackets, a nickel titanium wire segment, and fiber-reinforced composites (FRCs) for anchorage reinforcement...



Bone Formation and Gingival Improvement After Correction of Orthodontic Relapse

Volume 53 : Number 10 : Page 615 : Oct 2019

A 19-year-old female experienced gingival recession after unintentional activation of a bonded lingual retainer. Cone-beam computed tomography shows that orthodontic repositioning of the involved lower incisor promoted buccal bone regeneration and thus avoided the need for a gingival graft.



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.



Correction of Complete Upper Canine-Premolar Transposition with Palatal Miniscrew Anchorage

Volume 50 : Number 6 : Page 0 : Jun 2016

Transposed teeth, found in .3-.4% of the population, have been attributed to either genetic predisposition or a disturbance of eruption guidance. The maxillary arch is affected more frequently than the mandibular arch; the most common transpositions, in descending order, are canine-first premolar, canine-lateral incisor, canine in the site of the first molar, lateral incisor-central incisor, and canine in the site of the central incisor. In females, who are affected more often than males, transpositions occur more frequently on the left, whereas there is no side predilection in males. Associated dental anomalies include missing teeth, peg-shaped incisors, and supernumerary teeth.



Long-Term Stability of Two-Phase Class II Treatment with the Carriere Motion Appliance

Volume 53 : Number 8 : Page 481 : Aug 2019

The author reports a skeletal Class II case in which the Carriere Motion Appliance was used to establish a Class I platform during Phase I, thus improving the efficiency of Phase II correction with fixed appliances. Stability of the results is demonstrated five years after treatment.
