Abstract
An orthodontic appliance is often a combination of forces which have the task to provoke a reaction in the dento-alveolar structures. Unsufficient knowledge of the relation between the forces and the biological medium upon which they act, can provoke pathologic reactions. It is advisable therefore to apply forces which can be objectively registered. At the same time it is necessary to know the anatomic structures upon which we act, and the pattern of their reaction. Many authors have measured — by different methods — the dynamic forces acting upon the teeth through the pressure of the tongue, lips and cheeks. But small number of them measured the artificial forces which are daily applied in the orthodontic practice.
The authors of this paper give a survey of various constructions and methods of such measurements, as well as some basic information thus obtained.
