Tooth movement – clinical implications
International Orthodontics, 2010The tissue-based phenomena and the tissue interactions responsible for tooth displacement can be modulated by varying the intensity of the applied forces or by means of medicated molecules absorbed by the patient or prescribed by the orthodontist. However, harmful side-effects such as inflammatory root resorption or replacement resorption (ankylosis ...

The Journal of the American Dental Association, 1960
The three types of endogenous tooth movement are (1) the continuous eruption of teeth, (2) migration due to inherent weakness of the attachment apparatus, and (3) the adaptive movements of the teeth. Adaptive tooth movement is controlled by: (1) the contact relationships between adjacent and opposing teeth, and (2) the interaction of the components of ...

Medication and orthodontic tooth movement
Journal of Orthodontics, 2019As 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.

Osteoimmunology in orthodontic tooth movement
Oral Diseases, 2014The skeletal and immune systems share a multitude of regulatory molecules, including cytokines, receptors, signaling molecules, and signaling transducers, thereby mutually influencing each other. In recent years, several novel insights have been attained that have enhanced our current understanding of the detailed mechanisms of osteoimmunology.

Minimal forces in tooth movement
American Journal of Orthodontics, 1967Abstract 1. 1. The popularity and efficiency of light forces (that is, forces of small magnitude) in orthodontics suggest an analysis of the minimal forces produced by certain areas of the oral musculature and their influence on tooth position. 2. 2.

Proteoglycans and Orthodontic Tooth Movement
Journal of Orthodontics, 2001Proteoglycans 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 ...

Piezoelectric Tooth Aligner for Accelerated Orthodontic Tooth Movement
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018In 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 ...

Tooth movement in experimental malocclusion
Archives of Oral Biology, 1962Abstract In five human subjects, the occlusal surface of the right lower first permanent molar was raised by means of a removable metal cap approximately 0.5 mm thick. In every case the cap was an anatomical replica of the occlusal surface of the chosen tooth and was worn continuously without discomfort for 23–41 days.

Experimental tooth ankylosis and horizontal tooth movement in the pig
Archives of Oral Biology, 1981Abstract Experimental ankylosis was produced by 4 different techniques in deciduous premolar teeth of growing pigs. The most successful method was by thermal injury to the apex of the root. Measurements of the forward movement of the teeth were made on stone casts of the jaws taken prior to the production of ankylosis and after 16 weeks. Measurements

Biomechanical Principles of Tooth Movement
Dental Clinics of North America, 1981The major mechanical signals or stimuli in orthodontic therapy are the stress and the resultant strain or deformation in the periodontal supporting tissues. These signals are translated into biologic cellular activities by some yet unclear mechanisms. Direct action by the stresses and strains upon the cells as well as by secondary effects produced by ...
