Mathematical formalisms used in the orthodontic dynamics

This paper presents an orientation towards the medical engineering of the orthodontic dynamics. Mathematical formalisms, considered most representative, have selected. They are used in the actual detailed study of rather simple orthodontic processes. It is a enumeration of mathematical relations, limited in content and form, with the purpose of highlighting only the representative aspects of the calculation technique. A compromise has been used, for the simplest presentation of both medical phenomena and mathematical details associated to these phenomena. A unitary, synthetic and simple enumeration of the “medical phenomena - calculus technique binomial” was also wanted, as it gradually becomes a highly interest aspect in medicine, in general, and in the orthodontic dynamics, in particular.
