American Journal of Orthodontics, 1984
Orthodontic forces can be treated mathematically as vectors. When more than one force is applied to a tooth, the forces can be combined to determine a single overall resultant. Forces can also be divided into components in order to determine effects parallel and perpendicular to the occlusal plane, Frankfort horizontal, or the long axis of the tooth ...

γδT Cells Are Essential for Orthodontic Tooth Movement
Journal of dentistry research, 2021Sustained mechanical forces applied to tissue are known to shape local immunity. In the oral mucosa, mechanical stress, either naturally induced by masticatory forces or externally via mechanical loading during orthodontic tooth movement (OTM), is ...

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.

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 ...

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.

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 ...

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.

Clinical Dentistry Reviewed, 2017
The current concept of “pressure-tension” tooth movement is based upon reductionist explanations of parsed physiological processes that do not provide a cohesive understanding of clinically relevant tooth movement. The biology underlying accelerated orthodontic techniques have refocused attention on disruptions of tensional integrity of ...
