Abstract
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.
Highlights
The orthodontic movement depends on the application of forces to the tooth promoting compression of the periodontal ligament
The bone has a great variability in the trabecular bone density, as well as in its cortical thickness and morphology of the bone crest
Trabecular bone density The density of trabecular bone varies according with the skeletal region
Summary
Advancements in the knowledge of induced tooth movement: Idiopathic osteosclerosis, cortical bone and orthodontic movement. 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. The bone has a great variability in the trabecular bone density, as well as in its cortical thickness and morphology of the bone crest This extreme variability, when extreme, may influence significantly in more or less symptoms during orthodontic movement as well as the risk of root resorption. Avanços no conhecimento da movimentação dentária induzida Osteoesclerose idiopática, corticais ósseas e o movimento ortodôntico. An area can typically presents with bone as dense as the anterior region of the mandible, without which we must call it as it represents a bone sclerosis of trabecular variability given a functional demand. In regions of the mandibular angle or later the upper and lower third molars, including the tuberosity of the maxilla, there are patients with very loose areas or with normal bone rarefactions
