The Effect of Perturbations on Resistance to Sliding in Second Order Moments Using Conventional Ligated Brackets Versus Passive Self Ligated BracketsDownload
Abstract Objectives: A novel frictional and perturbation device was used to investigate the role of vibrations on resistance to sliding (RS) in conventional and passive ligated brackets Methods: 150 3M Victory Series twins (0.022 slot) and 150 Damon Q brackets (0.022 slot) were tested using an...
The Effect of Conventional Elastomers on Force and Moment of a Self-Ligating Orthodontic Bracket with Second-Order Angulation in the Dry and Wet States evaluated through a new 3D Friction DeviceDownload
Objective: A new three-dimensional friction device was used to investigate the effect of conventional elastomers on force and moment of a self-ligating orthodontic bracket with second-order angulation during a simulated retraction. Methods: An 0.018x0.025-in stainless steel archwire was drawn...
Many of the undesirable side effects that occur during orthodontic treatment can be attributed directly to a lack of understanding of the physics involved in a given adjustment of an orthodontic appliance. A large number of variables in orthodontic treatment are not within our control, such as...
