Numerical simulation of canine retraction by sliding mechanics
American Journal of Orthodontics and Dentofacial Orthopedics, 2005Bone remodeling laws have been used to simulate the movement of a single tooth, but the calculations for simulating the movement of several teeth simultaneously are time-consuming. The purpose of this article is to discuss a method that allows the simulation of more complex tooth movements.A 3-dimensional finite element method was used to simulate the ...

Dentoalveolar distraction osteogenesis for rapid orthodontic canine retraction
Journal of Oral and Maxillofacial Surgery, 2002We present a technique to reduce the overall orthodontic treatment time by means of dentoalveolar distraction osteogenesis.Eleven patients who were planned to undergo orthodontic treatment with bilateral first premolar extractions and subsequent bilateral canine tooth distalization underwent osteotomy around the canine tooth.

Retraction of Canines Using Bonded Tube-brackets
British Journal of Orthodontics, 1983Investigations using a Force Analyser were carried out to test the characteristics of retractor springs fitted to a removable appliance and designed for insertion into a tube-bracket, bonded to the buccal surface of a canine. The retractors were shown to produce a counter—rotation couple when activated on the typodont.

The effects of different sectional arches in canine retraction
The European Journal of Orthodontics, 1994The purpose of the present study was to compare the effects of Gjessing's canine retraction arch with a sectional arch including a reverse closing loop, which are both used for canine retraction in extraction cases. Our study involved both the maxilla and the mandible independently. After upper first premolar extractions and levelling of the teeth with

An Evaluation of Different Methods of Canine Retraction
British Journal of Orthodontics, 1977A Variety of different methods (17 in all) of retracting a canine tooth using fixed appliances with edgewise brackets are discussed in detail. The methods have been divided into two groups involving sliding the tooth along the archwire and moving the tooth with the archwire. The advantages and disadvantages of each method have been outlined.

[The ideal forces for canine retraction].
Orthodontike epitheorese : epiotemoniko periodiko tes Orthodontikes Etaireias tes Ellados, 1991In this study we analyze the factors, which are able to determine the ideal forces for teeth movement and especially canine retraction. These factors are the following: 1. Way of movement. 2. Anatomical situation. 3. Biological situation. 4. Personal factors. 5. Duration of movement. 6. The force control.

Changes over time in canine retraction: An implant study
American Journal of Orthodontics and Dentofacial Orthopedics, 2009The objective of this study was to analyze rates of canine movement over the first 2 months of continuous retraction, when rate changes are expected.Ten patients with bone markers placed in the maxilla and the mandible had their canines retracted over a 2-month period. Retraction was accomplished with beta-titanium alloy T-loop springs. Standardized 45
