Intermittent Force in Orthodontic Tooth Movement

Journal of Dental Research, 2001
A single orthodontic activation lasting one hour can initiate tooth movement. The purpose of this study is to examine tooth movement, osteoclasts, and root resorption in rats following several one-hour activations. Rats (n = 144) were randomly assigned to intermittent (multiple activations of 1 hr/day), continuous, and sham appliances.

Accelerated orthodontic tooth movement: Molecular mechanisms

American Journal of Orthodontics and Dentofacial Orthopedics, 2014
Accelerating orthodontic tooth movement can significantly reduce treatment duration and risks of side effects. The rate of orthodontic tooth movement is chiefly determined by the remodeling of tissues surrounding the roots; this in turn is under the control of molecular mechanisms regulating cellular behaviors in the alveolar bone and periodontal ...

Clear Aligners Generations and Orthodontic Tooth Movement

Journal of Orthodontics, 2016
Clear aligner technology has evolved over the last 15 years, with these appliances continually being modified to increase the range of tooth movements that they can achieve. However, there is very little clinical research available to show how these appliances achieve their results.

Studying Orthodontic Tooth Movement in Mice

Journal of Visualized Experiments
Orthodontic tooth movement (OTM) represents a dynamic process in which the alveolar bone undergoes resorption at compression sites and deposition at tension sites, orchestrated by osteoclasts and osteoblasts, respectively. This mechanism serves as a valuable model for studying various aspects of bone adaptation, including root resorption and the ...

Tooth transplantation and orthodontic movements

International Journal of Orthodontic Rehabilitation, 2020
Dental autotransplants have been performed successfully for many years, but little has been written about its relationship with orthodontics. This article is a review which analyses and highlights all the details about the orthodontic movement in autotransplanted teeth according to their root development.

Neurologic Regulation and Orthodontic Tooth Movement

2015
Pain and discomfort are prevalent symptoms among the vast majority of patients with fixed orthodontic appliances and is the most disliked aspect of treatment. The periodontium is a highly innervated structure that also provides the necessary trophic factors, such as nerve growth factor, which promote neuronal survival, maintenance and axonal growth ...

Orthodontic tooth movement and HMGB1

Journal of Oral Biosciences, 2018
Abstract Background High mobility group box 1 (HMGB1) has been recognized as a DNA binding protein that modulates transcription, and is secreted by activated dendritic cells, macrophages, and necrotic cells. Alveolar bone resorption in the compression zone and bone formation in the tension zone of the periodontal ligament (PDL) ensure that it is ...

microRNA-21 Contributes to Orthodontic Tooth Movement

Journal of Dental Research, 2016
microRNAs could be mechanosensitive and emerge as critical posttranscriptional regulators in the bone-remodeling process. During orthodontic tooth movement (OTM), the application of mechanical force induces alveolar bone remodeling, but whether microRNAs respond to orthodontic force and contribute to OTM is unknown.

Orthodontic Tooth Movement: A Historic Prospective

2015
The earliest report on orthodontic tooth movement in the English literature was published in 1911. Oppenheim carried out studies on baboons to determine what histologic changes occurred during tooth movement. Reitan and many others carried out research into the nature of tooth movement.

Role of CCR2 in orthodontic tooth movement

American Journal of Orthodontics and Dentofacial Orthopedics, 2012
Cytokines and chemokines regulate bone remodeling during orthodontic tooth movement. CC chemokine ligand 2 (CCL2) is involved in osteoclast recruitment and activity, and its expression is increased in periodontal tissues under mechanical loading. In this study, we investigated whether the CC chemokine receptor 2 (CCR2)-CCL2 axis influences orthodontic ...
