Classification et analyse des déplacements squelettiques craniofaciaux par la méthode des superpositions structurales

During implant studies of facial growth, the recognition of stable anatomical structures has given rise to the development of a so- called structural cephalometric superimposition method. By combining this concept with studies on modelling of the shape of the facial skeleton, four categories of skeletal displacement have been identified. In order to demonstrate clinically these different forms of displacement it is necessary to adapt the method by recognizing a new general superimposition stage in order to show the individual involvement of the various craniofacial constituents in global skeletal displacements.
