Introduction

Orthodontic diagnosis is, in general, essentially morphological and so is the treatment, since it is most often a matter of modifying the shape of the arches and their relationships to adjust them to a standard with the goal of a beautiful smile. The dental arches are primarily used for chewing: it is even their main function.

Materials and Methods

In this article, the author describes what systemic orthodontics (and therefore diagnosis) is, by addressing the fields of mastication, mandibular kinematics, and the various movements generated, among others. His remarks are illustrated by the study of a clinical case.

Discussion

The morphological modifications that our appliances impose on the arches must be adapted to an efficient physiological mastication because the stability of orthognathodontic corrections depends on it, including surgical corrections.

Conclusion

The adequacy between shape and mastication, which is concretized by the search for an optimal proprioception, must be our first objective. The treatment modifies the shape of the arches and their articulation to change the trajectories of the mastication cycles, which should allow a better distribution of the stresses on all the teeth and ensure the durability of the corrections.
