[Vertical control and orthopedic therapy].

Control of the vertical development of the face is a key element in assuring the success of orthopedic treatment, as much for its effects on anterior vertical dimension as for its influence on correction of the sagittal discrepancy between the jaws. An effective management of this control demands respect for the equilibrium between posterior and anterior face, as described by Schudy. The authors review the details of the application of orthopedic therapy on the different elements of this equilibrium and then, present the modalities of vertical control appropriate to each appliance.

[Orthopedic approach to asymmetry].

Asymmetry being a clinical manifestation of various pathologies, the orthopedic attitude greatly varies from one practitioner to another. Thanks to a better knowledge of the etiopathogenesis, the orthopedic approach in some particular cases reveals very effective, either alone or together with other therapeutics. In mandibular laterodeviations most often consecutive to a maxillary contraction, the best treatment is to expand maxilla which will allow a mandibular centric repositioning.
