The fundamentals of tooth movement
International Orthodontics, 2010Advances in the field of molecular phenomena have led to a fuller understanding of the mechanisms at work in tooth movement. The forces applied by orthodontic devices are converted into cellular signals via the deformation of the bony walls and the inflammatory reaction they trigger.

1. Tooth movement relative to the alveolar bone can be precisely described only by superimposing on fixed points in the bone. Implants are the best known way today. Over short-term studies laminagraphy and the use of bony trabeculations are also useful.

Orchestration of tooth movement
American Journal of Orthodontics, 1983Recent advances in the art and mechanics of delivering orthodontic forces have achieved greater precision and control of tooth movement. The exact mechanism by which these forces orchestrate tooth movement is not thoroughly understood. An accurate understanding and precise control over the factors responsible for initiating and carrying out the tissue ...

A n earlier study of force and rate of orthodontic tooth movement provided enough data to challenge the clinical usefulness of the theories of optimal force and differential force.2 Unfortunately, certain artifacts (namely, tipping tooth movement) which confounded the optimal force theory were also present in our previous data.

Prostaglandins and tooth movement
The European Journal of Orthodontics, 1984The effect of flurbiprofen, a prostaglandin cycloxygenase inhibitor, on tooth movement was studied using New Zealand white rabbits. Under general anaesthesia, springs were ligated between the lower first molars and incisors resulting in approximation of these teeth.

Critical Reviews in Oral Biology & Medicine, 1991
This article reviews the evolution of concepts regarding the biological foundation of force-induced tooth movement. Nineteenth century hypotheses proposed two mechanisms: application of pressure and tension to the periodontal ligament (PDL), and bending of the alveolar bone.

T he tooth-supporting structures of bone and connective tissue provide not only the bioelastic but also the bioplastic foundations upon which the dentition functions. Study of tooth function, then, in its widest sense, involves bioelastic phenomena and consideration of those compressive and tensile forces which exceed, in duration and magnitude, the ...

Leukotrienes in orthodontic tooth movement
American Journal of Orthodontics and Dentofacial Orthopedics, 1989Prostaglandins (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.

Tooth movement into edentulous areas
The Journal of Prosthetic Dentistry, 1971Abstract Movement of teeth into edentulous spaces created by the loss of teeth within a dental arch was reported from three aspects: (1) movement of the tooth mesial to the space into the space, (2) movement of the tooth distal to the space into the space, and (3) movement of the tooth opposing the space into the space.

Kinematics of the tooth tapping movement
Journal of Oral Rehabilitation, 1977SummaryElectrical activity in the masseter muscles and tooth contact vibrations were recorded simultaneously from subjects tapping their teeth slowly into maximal intercuspidation and again with maximal frequency. High speed cinephotography was also used with four of the ten subjects.Three main parts could be distinguished on the obtained graphical ...
