introduction: corticotomy-facilitated orthodontics provides a means for rapidly moving teeth purportedly with little damaging effects to the periodontium and with greatly reduced treatment time. the aim of this study was to enhance the orthodontic tooth movement by reducing the cortical bone layer (resistant to bone re-sorption relative to spongious bone) following erbium, chromium doped yttriu...

Background and Aim: Estrogen affects the metabolism in females. This study aimed to assess the effect of absence of estrogen on orthodontic tooth movement in rats. Materials and Methods: In this animal study, 55 rats were randomly divided into four groups. Group 1 (n=10) had intact ovaries. In group 2 (n=15), ovaries were intact but the rats were subjected to stress due to tooth preparation. I...

tramadol is a synthetic analgesic of opioids which has more flexible mechanisms of action than typical opioids. since it has been reported in previous study that typical opioids like morphine can affect the bone homeostasis, it is worthwhile to examine the effects of tramadol on tooth movement. in this study we investigated effects of tramadol on orthodontic tooth movement in rats.30 male wista...

The bone remodeling process involved in orthodontic tooth movement consists of bone resorption on the compression side and bone formation on the tension side of the teeth. Osteoclasts play an important role in bone remodeling and are necessary for orthodontic tooth movement. Receptor activator of nuclear factor-κB ligand (RANKL) is essential for osteoclast formation and differentiation. Several...

Alveolar augmented corticotomy is effective in accelerating orthodontic tooth movement, but the effect only lasts for a relatively short time. Therefore, the purpose of this study was to investigate the underlying biology of the immediate periodontal response to orthodontic tooth movement after a corticotomy with alloplastic bone grafts. The results demonstrated that measurable tooth movement b...

Surgical technique to accelerate the rate of orthodontic tooth movement has been recognized in many case reports. It is a clinically successful method used for mature patients, where time of orthodontic treatment may be important in preferred groups of patients. The alveolar bone remodeling and PDL are the significant factors in orthodontic tooth movement, and bone turnover is identified to enl...

There is no consistent relationship between malocclusion and periodontal disease but certain characteristics of malocclusion can promote a pathologic environment conducive to periodontal disease. One of the dramatic means available to improve the local environmental factors is through orthodontic tooth movement. The pretreatment periodontal conditions can include excessive tooth mobility, advan...
