Moving teeth orthodontically through the dense trabecular bone and cortical areas may require a reduction in the intensity and/or concentration of the applied forces. In part, the orthodontic applied forces are dissipated and reduced by bone deflection, which normally occurs by a slight degree of elasticity of bone tissue in normal conditions. In areas of dense trabecular and in cortical bone this deflection should be insignificant or nonexistent. If there is no reduction in the intensity of the forces in these mentioned regions, the entire force will focus on the structure of the periodontal ligament, increasing the risk of death of cementoblasts, hyalinization and root resorption. Further studies could assess the prevalence of these consequences in populations selected for this purpose, so that would no longer be randomly observed notes.
