A Numerical Simulation of Orthodontic Tooth Movement Produced by a Canine Retraction Spring
Orthodontics Canine retraction Finite element method
2009/9/14
Tooth movements produced by a canine retraction spring were calculated. Although a gable bend and an anti-rotational bend were incorporated into the spring, the canine tipped and rotated initially. Re...

Nickel-titanium spring properties in a simulated oral environment
Nickel-Titanium Spring Mechanics
2009/1/12
A study of nickel-titanium springs was undertaken to determine whether their mechanical properties are affected by prolonged exposure to a static, simulated oral environment. Stainless steel springs...
An analytical evaluation of a new spring design for segmented space closure
Geometric nonlinearities Segmental spring Translational unit Anchorage unit Applied force Effective force Limit of activation Activator
2009/1/12
Contemporary segmented-arch space-closure springs require activation techniques that have the side effect of producing a significant amount of geometric nonlinearity. This nonlinearity makes these s...
Specialized Spring Design in Segmented Edgewise Orthodontics：Further Verification of Dedicated Software
Spring design Dedicated software Experimental-analytical comparison
2008/12/29
A software program for use in the investigation of specialized springs used in the segmented arch technique has previously been developed and an example of its clinical application has been shown....
A Cephalometric Study of the Class II Correction Effects of the Eureka Spring
Class II Noncompliant interarch force Intrusion
2008/12/26
The effect of the Eureka Spring (ES) appliance was investigated on 37 consecutively treated, noncompliant patients with bilateral Class II malocclusions. Lateral cephalographs were taken at the st...
Experimental Force Definition System for a New Orthodontic Retraction Spring
Retraction springs Segmental arch Anchorage unit
2008/11/27
A new geometry of orthodontic retraction spring was experimentally studied through an electronic device (platform for measuring forces), using strain gauges that were adapted to cantilever beams. The ...
Curvature Versus V-Bends in a Group B Titanium T-Loop Spring
T-loops Moment to force ratios Group B anchorage TMA Loop software
2008/10/30
Objective: To compare the system of forces acting on curvature and preactivated V-bends in titanium T-loop springs (TTLSs) made of 0.017- × 0.025-inch TMA (titanium molibdenium alloy) wire.Materials a...
