Adjusting Force Vectors During Maxillary Retraction with Miniscrew Anchorage

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...



Mesialization of Mandibular Molars with Clear Aligners in a Young Class II, Division 2 Patient

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.



Treatment of an Adult Patient with Vertical Maxillary Excess Using Miniscrew Fixation

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...



"Surgery-First" Approach with Invisalign Therapy to Correct a Class II Malocclusion and Severe Mandibular Retrognathism

Volume 53 : Number 7 : Page 397 : Jul 2019

The “surgery-first” approach appeals to adults who wish to avoid a temporary worsening of their facial appearance during presurgical orthodontics. Drs. Chang, Steinbacher, Nanda, and Uribe show how postsurgical aligner therapy can further enhance the esthetics and acceptability of treatment for such patients.



Forced Extrusion of an Endodontically Treated Lower Incisor Prior to Extraction

Volume 57 : Number 8 : Page 459 : Aug 2023

In this case, a periodontally comprised lower central incisor is orthodontically extruded before its extraction, preserving alveolar bone for a lingually blocked-out incisor to replace it. Prior endodontic treatment allows progressive incisal grinding of the extruded incisor to avoid occlusal trauma.



Nonsurgical Treatment of an Adult Skeletal Class III Patient with Compensated Dentition

Volume 55 : Number 11 : Page 701 : Nov 2021

Although orthodontic camouflage is possible in moderate adult skeletal Class III cases, decompensation may disrupt the dental-periodontal equilibrium. Drs. Rahima, El-Beialy, and Mostafa demonstrate the use of short Class III elastics to avoid complications associated with conventional intermaxillary elastics.



Nonextraction Treatment of an Open Bite with a Preadjusted Lingual Appliance and Intermaxillary Elastics

Volume 50 : Number 10 : Page 0 : Oct 2016

This case report describes retreatment of an adult open-bite patient using a preadjusted lingual appliance and intermaxillary lingual elastics, combined with logopedic therapy. Diagnosis and Treatment...



Autotransplantation of a Fully Developed Maxillary Premolar to a Missing Mandibular Premolar Site

Volume 47 : Number 3 : Page 199 : Mar 2013

Agenesis of one or more teeth is among the most common developmental anomalies encountered by orthodontists.1 The reported incidence of permanent-tooth agenesis varies from 1.6% to 9.6%--excluding thi...



Nonextraction "Surgery First" Treatment of a Skeletal Class III Patient with Severe Maxillary Crowding

Volume 47 : Number 5 : Page 297 : May 2013

Recently introduced "surgery first" treatment protocols achieve immediate facial improvement for orthognathic patients by eliminating the presurgical orthodontic treatment phase.1-5 Because prediction...



Treatment of Chronic Adult Periodontitis in a Patient with Negative Overjet and Multiple Tooth Loss

Volume 50 : Number 4 : Page 0 : Apr 2016

Orthodontic treatment is complicated in adults with periodontal disease, requiring advanced biomechanical techniques, an understanding of the patient's specific biological situation, and an interdisci...



Translation of a Tooth Across the Suture to Replace a Fused Upper Central Incisor

Volume 56 : Number 6 : Page 353 : Jun 2022

The authors show a multidisciplinary case in which a central incisor and its fused supernumerary are extracted, and the contralateral incisor is moved across the midline into its place. An available supernumerary lateral incisor is then moved into the position of the relocated central incisor.



Anterior Repositioning Appliance for Relief of TMD in Conjunction with Definitive Orthodontic Treatment

Volume 57 : Number 11 : Page 683 : Nov 2023

An orthotic is used to treat disc displacement with reduction while the occlusion is stabilized by orthodontic fixed appliances and Class III elastics. The orthotic is progressively equilibrated and cut back as the lower posterior teeth are extruded.



Treatment of a Patient with Apparent Primary Failure of Eruption Using a Modified Hyrax Expander and Miniplate Anchorage

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.



Miniplate Anchorage for Correction of Skeletal Anterior Open Bite in an Adult

Volume 54 : Number 3 : Page 175 : Mar 2021

Treatment of anterior open bite is more challenging in non-growing patients. This report documents the correction of an adult patient’s skeletal open bite using T-shaped miniplates installed in the zygomatic pillars and in the external mandibular cortical bone.



Miniscrew-Assisted Treatment of a Transposed and Horizontally Impacted Upper Central Incisor

Volume 51 : Number 8 : Page 461 : Aug 2017

The authors describe the successful correction of a rare upper lateral-central incisor transposition associated with dilaceration and horizontal impaction of the central incisor. Cone-beam computed tomography is used for diagnosis and a miniscrew with a special accessory wire for indirect anchorage.



Two-Stage Treatment of Skeletal Class III Malocclusion with Arch-Width Discrepancy and Lower Incisor Agenesis

Volume 53 : Number 5 : Page 291 : May 2019

Dr. Li Cao and colleagues describe the case of a growing Class III patient with two missing lower incisors who was treated with a two-stage approach, involving a protraction facemask followed by upper first-premolar extractions and orthodontic camouflage therapy.



Retreatment of a Skeletal Class III Malocclusion Using Mandibular Extra-Alveolar Mini-Implants

Volume 55 : Number 9 : Page 561 : Sep 2021

Extra-alveolar skeletal anchorage in the mandibular buccal shelf can allow the entire mandibular dentition to be distalized, avoiding the need for extractions, Class III elastics, or other compensatory strategies, as a case report illustrates.



Treatment of Skeletal Class II Open Bite with the Triple Intrusion System

Volume 52 : Number 8 : Page 427 : Aug 2018

The authors introduce a reliable method for treating an adult open-bite patient with maxillary vertical excess and a retrognathic mandible. This case report illustrates a triple intrusion system that uses a multipurpose implant, posterior maxillary cap splints, and palatal miniscrews to enable maxillary posterior retraction and mandibular anterior rotation.



Surgical-Orthodontic Treatment of a Patient with Severely Asymmetrical Skeletal Class III Dentofacial Deformity

Volume 54 : Number 7 : Page 210701 : Jul 2021

The authors demonstrate how accurate evaluation of an asymmetrical skeletal Class III can enable comprehensive surgical-orthodontic treatment to correct the skeletal discrepancies in all three planes of space, producing optimal occlusal function, facial esthetics, and long-term stability.



Maxillomandibular Advancement with a "Surgery First" Approach and Invisalign for Treatment of Obstructive Sleep Apnea

Volume 56 : Number 1 : Page 49 : Jan 2022

This adult Class III patient with moderate-to-severe OSA was unable to tolerate continuous positive airway pressure. The authors show how his situation was resolved with maxillary and mandibular osteotomies, followed by clear aligner therapy with miniscrews for attachment of elastics.
