Shape changes due to functional appliances.
Functional appliances are now routinely used in orthodontic treatment to correct anteroposterior skeletal discrepancies, based on the assumption that existing functional patterns can be modified to yield a new morphological pattern. However, the mechanisms by which this correction occurs remain in dispute as current measurement procedures, primarily mathematical, do not adequately describe shape changes. This paper introduces a new measurement method, Fourier descriptors, to clinical dentistry.
