Fiber-Reinforced Composite Space Maintenance for Anterior Implant Therapy
Volume 41 : Number 6 : Page 0 : Jun 2007
Dental implants, like ankylosed teeth, do not follow the growth of the facial bones. Considering the risk of apical displacement, therefore, implants are contraindicated until the completion of maxill...

Use of 3D Metrology Software to Analyze Aligner Treatment Outcomes after Lower-Incisor Extractions
Volume 57 : Number 12 : Page 747 : Dec 2023
Extraction of a single lower incisor and interproximal reduction can facilitate clear aligner treatment for the relief of severe crowding. Drs. Giulieri, Weir, and Freer use a 3D modeling program to assess the accuracy of such treatment, as compared with the predicted results.

Distal Movement of Lower Molars with Miniplate Anchorage
Volume 49 : Number 10 : Page 0 : Oct 2015
The permanent teeth most likely to become impacted are the upper and lower third molars and the upper canines, followed by the lower premolars. Impaction of lower first permanent molars is rare, with an estimated prevalence of .01%. Treatment options include extraction, with or without osseointegrated implant placement, dental luxation, or orthodontic loading; orthodontic treatment with intra- or extraoral devices; and orthodontic extrusion with screws or plates as temporary skeletal anchorage. Because normal eruption of the lower first and second molars is essential for development and coordination of the dental arches and the facial skeleton, a conservative treatment plan aimed at proper positioning of these teeth in the mandibular arch should be considered whenever possible.

The Lingual Arch in the Mixed Dentition
Volume 7 : Number 2 : Page 111 : Feb 1973
A large percentage of patients referred for orthodontic treatment are in the mixed dentition. When they are referred in the early mixed dentition, the orthodontist usually suggests postponement of com...

Treatment of Multiple Ankylosed Teeth Using a Piezoelectric Device
Volume 47 : Number 11 : Page 656 : Nov 2013
Ankylosis is a fusion of alveolar bone with the cementum and/or dentin that may occur either before or after tooth eruption.1 The molars, particularly the mandibular second deciduous molars, are most ...

Interdisciplinary Treatment of Gingival Recession
Volume 50 : Number 2 : Page 0 : Feb 2016
Gingival recession may be localized or generalized, but always involves at least one tooth surface. It occurs more often in the mandibular arch than in the maxillary arch. Gingival displacement can become a critical complication, leading to esthetic complaints, root sensitivity, loss of periodontal attachment, difficulty in performing oral hygiene, and increased risk of root caries. Exposed root surfaces are also more prone to abrasion from brushing.

Volume 50 : Number 9 : Page 0 : Sep 2016
Pathological migration of anterior teeth, which is related mainly to bone loss, is common among periodontally compromised patients.1,2 Its overall prevalence is reportedly between 30%2 and 55.8%.1 Ext...

Differential Diagnosis and Treatment of Condylar Hyperplasia
Volume 53 : Number 1 : Page 29 : Jan 2019
Planning treatment for a patient with condylar hyperplasia requires careful investigation of the etiology. In this case, technetium 99m imaging indicated that the patient could be treated first by mandibular distraction and orthognathic surgery, avoiding the need for condylectomy.

Introduction to LightForce Part 1: 3D-Printing the Next Generation of Fixed Appliances
Volume 57 : Number 9 : Page 500 : Sep 2023
Additive manufacturing represents the most recent evolution of CAD/CAM technology in orthodontics. Drs. Waldman, Moshiri, and Bonebreak-Jackson describe how LightForce 3D-printed polycrystalline alumina brackets and LightPlan cloud-based software enable fully customized treatment. A typical case is presented.

Open-Bite Treatment Using Maxillary and Mandibular Miniplates
Volume 49 : Number 6 : Page 398 : Jun 2015
The development of temporary anchorage devices (TADs) has offered new options for treating orthodontic problems such as anterior open bite by means of molar intrusion, Class II malocclusion by maxilla...

A Simple Prediction Method for "Surgery First" Treatment of Skeletal Class II Malocclusions
Volume 58 : Number 7 : Page 428 : Jul 2024
Drs. Khattab, Lutfi, Alzarif, Almallah, and Alawad present a simple acrylic trial splint that simulates the results of mandibular-advancement surgery, avoiding the need for complex technology in treatment planning. The splint then serves as a surgical wafer during the procedure.

Orthodontic Traction of Impacted Upper Canines Using the VISTA Technique
Volume 51 : Number 2 : Page 0 : Feb 2017
Upper canines have the longest and most complicated period of tooth development. Because they begin mineralization before the first molars and incisors and take twice as long to completely erupt, they are more susceptible to changes in the normal eruption pathway, leading to the common clinical problem of impaction. The prevalence of impacted upper permanent canines is approximately 1-3% -- more than for any other teeth except the third molars. Palatal impaction is two to three times more common than buccal impaction.

Volume 56 : Number 10 : Page 567 : Oct 2022
The sliding jig presented by Drs. Pithon, Vieira, Souza, and Freitas is designed to move teeth laterally with support from mini-implant anchorage, thus avoiding unwanted side effects. A complex case is shown in which an incisor was moved across the midline.

Class III Correction Using Clear Aligners, Sectional Wires, and Miniscrew Anchorage
Volume 57 : Number 1 : Page 54 : Jan 2023
Dr. Arveda and colleagues demonstrated a technique in which clear aligners are trimmed to allow placement of a partial fixed labial appliance with anchorage from a retromolar miniscrew. A case involving extraction of a single lower incisor illustrates their method.

Atypical Extractions in Adult Treatment
Volume 49 : Number 5 : Page 312 : May 2015
