Proteoglycans and Orthodontic Tooth Movement

Journal of Orthodontics, 2001
Proteoglycans represent an important and diverse family of extracellular matrix components within the connective tissues of the periodontium. This review focuses on the function and metabolism of the various proteoglycans in periodontal tissues, such as alveolar bone and periodontal ligament, and considers their potential fate in response to an ...

Medication and orthodontic tooth movement

Journal of Orthodontics, 2019
As any pharmaceutical substance may influence the events associated with orthodontic tooth movement, it is of importance for the clinician to be able to recognize any prospective patient’s history and patterns of medicinal consumption. This review presents the effects of various commonly prescribed medications on the rate of orthodontic tooth movement.

Leukotrienes in orthodontic tooth movement

American Journal of Orthodontics and Dentofacial Orthopedics, 1989
Prostaglandins (PGs) and leukotrienes (LTs) are products of arachidonic acid conversion. PGs have an established role in mediating orthodontic tooth movement. The role of LTs in modulating or mediating orthodontic tooth movement was investigated in this study.

Piezoelectric Tooth Aligner for Accelerated Orthodontic Tooth Movement

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
In this paper, we propose a device that can induce vibration to potentially accelerate the rate of orthodontic tooth movement and thus reduce the duration of the orthodontic treatment. This is accomplished by harmonically exciting a polyvinylidene fluoride (PVDF) piezoelectric actuators to generate vibration and hence generate cyclic loading at 30 Hz ...

Osteoclast polarization and orthodontic tooth movement

Orthodontics & Craniofacial Research, 2009
Structured AbstractAuthors –  Holliday LS, Ostrov DA, Wronski TJ, Dolce CIntroduction –  Osteoclasts polarize when they contact activation signals that are associated with bone. Polarization is required for bone resorption and involves highly specialized mechanisms that represent attractive targets for the development of osteoclast‐specific therapeutic

Prediction of orthodontic tooth movement

American Journal of Orthodontics, 1976
Orthodontics is rapidly advancing from the stage of fortuitous success to one of planned success. When appliance design is based on simple concepts of equilibrium, prediction of desirable and undesirable tooth movement becomes possible. The flow chart that has been presented allows the clinician to systematically treat dental discrepancies more ...

Tooth eruption and orthodontic movement

British Dental Journal, 1992
Teeth have been moved in man for centuries and the process of tooth eruption has occurred presumably since he evolved. The cellular and molecular mechanisms which are involved in these two phenomena are amongst the most intriguing questions in dental research today.

Internal Resorption Complicating Orthodontic Tooth Movement

British Journal of Orthodontics, 1984
A case report is presented of an orthodontic patient who suffered internal resorption and a consequent ‘pink spot’ affecting a maxillary central incisor. Its management is outlined. The aetiology and possible cellular events responsible are discussed.

NSAID Impairment of Orthodontic Tooth Movement

Annals of Pharmacotherapy, 2001
OBJECTIVE: To evaluate the impairment of orthodontic tooth movement caused by nonsteroidal antiinflammatory drugs (NSAIDs). DATA SOURCES: Biomedical literature accessed through MEDLINE (1966–January 2000), EMBASE (1980–January 2000), and International Pharmaceutical Abstracts(1970–January 2000). Key search terms included NSAIDs, orthodontics, and tooth

Osteoblast differentiation during orthodontic tooth movement

Orthodontics & Craniofacial Research, 2019
AbstractObjectivesTo analyse the expression of osteoblast differentiation markers and osteoclast activity in the periodontal ligament (PDL) following 2, 4 and 7 days of orthodontic tooth movement (OTM) in an animal model.Setting and Sample PopulationEighteen C57BL/6 wild‐type mice.Material and MethodsFor the OTM model, orthodontic force was applied to ...
