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.

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.

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 ...

Prediction of orthodontic tooth movement
American Journal of Orthodontics, 1976Orthodontics 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 ...

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 ...

Tooth eruption and orthodontic movement
British Dental Journal, 1992Teeth 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.
