Aligner Treatment of Transposed Maxillary Canines and Lateral Incisors
Volume 55 : Number 1 : Page 34 : Jan 2021
Aligner therapy can now be employed to accommodate forced eruption of transposed canines and lateral incisors, using auxiliaries such as elastomeric traction applied directly to the trays. The authors present a typical treatment involving a 13-year-old female patient.

CASE REPORT
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.

Extrusion of Ankylosed Maxillary First Molars Using a Boneborne Vertical Distractor
Volume 58 : Number 2 : Page 110 : Feb 2024
A vertical periodontal ligament distractor is described by Dr. Schmid-Herrmann and colleagues for use in patients with ankylosed upper first permanent molars. The appliance consists of two Beneplates welded together, an open expansion screw, and a cantilever arm to erupt the ankylosed tooth after luxation.

A Combined Fixed-Removable Approach to the Treatment of Impacted Maxillary Canines
Volume 9 : Number 3 : Page 162 : Mar 1975
There was a time in Europe when it was generally considered that all orthodontic movements could be effected by removable appliances alone. With the evolution of multibanded techniques, it has been sh...

Cephalometric Evaluation of Skeletal Open- and Deep-Bite Tendencies
Volume 26 : Number 6 : Page 0 : Jun 1992
The influence of mandibular growth rotation in the development of deep or open bites before, during, or after orthodontic intervention has been the subject of extensive investigations over the past 40...

Statically Determinate Transpalatal Arches
Volume 28 : Number 10 : Page 0 : Oct 1994
Passive transpalatal arches, used for reinforcement of anchorage, can be either soldered to molar bands or bent to fit passively into lingual sheaths or brackets.1-7 However, transpalatal arches can a...
