Biomechanical Modeling of Canine Retraction

open access: green, 2012
Objective: To create a comprehensive finite element model capable of analyzing the biomechanics of canine retraction. Methods: A half maxilla virtual model with an extracted first premolar was created from human computed tomography data. Accurate brackets and an 0.018 archwire were placed to model canine retraction under 0.5N and 1.0N of retraction ...

Optimizing anterior and canine retraction

American Journal of Orthodontics, 1976
Vertical loops or modified vertical loops are basically frictionless springs which are used for canine and anterior tooth retraction. The design and selection of a proper loop or retraction spring should be based on a number of scientific criteria.

Canine retraction with J hook headgear

American Journal of Orthodontics, 1980
Several methods have been described for accomplishing distal movement of canines without losing posterior anchorage. An accepted method in canine retraction is the use of headgear with J hooks. Since it incorporates extraoral anchorage, it is most effective in maximum-anchorage cases.

Maxillary canine retraction, periodontal surgery, and relapse

American Journal of Orthodontics, 1980
Extraction spaces closed during the course of orthodontic therapy tend to re-open, whereas orthodontically rotated teeth are prone to relapse. One of the major causes of spaces opening between teeth is the supra-alveolar soft tissues which do not always adapt to the new tooth positions.

Canine retraction: A photoelastic study

American Journal of Orthodontics, 1975
0 rthodontists have always been aware of the need for root control when a tooth is being moved through bone. I-3 However, of the early men, Case seemed to understand best the mechanics of root control, and he devised sophisticated appliances that attempted to shift coronally applied forces apically. He also denounced the many orthodontists who held the
