Orthodontics &Craniofacial Research, EarlyView.ABSTRACT Objective This study aimed to analyse the three‐dimensional forces acting on maxillary teeth with aligners activation of en‐masse retraction based on the different attachment positions in vitro. Methods Three groups were designed for the same 0.25 mm en‐masse retraction forces with three different attachment positions.

Orthodontic Open-Coil Spring Deactivation Forces Differ with Varying Activation Levels [PDF]
, 2018 Coil springs are used in orthodontics to deliver forces to move teeth. However, the optimal amount of activation to produce predictable, continuous deactivation forces, for the purpose of orthodontic tooth movement, is unclear.

Applied materials engineering for orthodontic wires
Australasian Orthodontic Journal, 1989 Abstract In Australia, the history of materials engineering for orthodontic wires is generally related to the development of the Begg appliance. Therefore, until recently, it has helped in the search for light resilient forces produced by fine high-tensile stainless steel wires.
