Objective:
The aim of this study was to visualize and quantify root displacements in the bone base of a patient before orthodontic treatment and obtain an optimal set-up that would include information on both coronal and root movements.
Material And Method:
Data from a patient's scan records, the initial plaster model and scanned set-up are migrated into the Amira® software for advanced mesh and surface analysis. Using this software, each tooth of the initial 3D-reconstruction scan is isolated then superimposed over that of the initial model. The set-up is then positioned onto the initial model at second molar level and dragged onto the initial 3D reconstruction. Lastly, the roots are repositioned on the crowns on the set-up.
Results:
This study enabled the visualization and quantification of dental displacements (crowns and roots) from initial to expected final position in a three-dimensional space reconstruction.
Discussion-Conclusion:
This technique, carried out routinely thanks to the advent of cone beam tomography, can help optimize orthodontic treatments, notably by anticipating root proximity issues during set-up preparation.

Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
