MECHANICAL ANALYSIS OF ORTHODONTIC WIRES

Diyala Journal of Engineering Sciences, 2012
Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth.
