Orthodontic torque expression is the result of axial rotation of rectangular archwires within a rectangular bracket slot. This study investigates the effect of bracket material on torque expression. Torque exerted by a rotating archwire on each bracket will be measured as well as the relative...
The design and testing of an orthodontic torque simulator that reproduces the effect of archwire rotation on orthodontic brackets is described. This unique device is capable of simultaneously measuring the deformation and loads applied to an orthodontic bracket due to archwire rotation. Archwire...
The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile – digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The...
The Crowsnest Pass area, located in the Rocky Mountain foothills of the Canadian Cordillera, provides an exceptional example of a thin-skinned thrust belt from which the deformational history can be determined. Use of LiDAR (light detection and ranging) data, acquired by high-resolution remote...
Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...
Braces are commonly used to correct misalignments or malocclusions in the mouth. One particular orthodontic treatment utilizes archwire rotation to control the anterior inclination of a tooth and motion is achieved through the interaction of a rectangular archwire within the rectangular bracket...
Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine...
Deformation of the orthodontic bracket upon wire engagement may result in torque dissipation within the bracket rather than transmission to the tooth and its supporting structures. The purpose of this study was: 1) quantify the amount of torque expression and 2) quantify any deformation as a...
