[Surgery of asymmetry].

Endeavoring to present, within a few pages, an exhaustive work of all the surgical proposals, regarding the multitude of ethiopathogeneses, is quite utopic. The author considers the evaluation of the asymmetrical patient and underlines in the complementary examinations the advantage of 3D tomodensitometry. A chapter is devoted to presurgical orthodontic preparation aimed at counteracting the compensations, which affect the maxillary and mandibular alveolar support.

[Three-dimensional imaging and cephalometry of cranio-facial asymmetry].

The 75th meeting of the French Orthodontics Society will be held in Biarritz May 8-9-10-11 2002. The main topic for discussion will be: "facial asymmetry". During the meeting, authors will present study of facial asymmetries using a new innovative three-dimensional cephalometry.

[3-dimensional cephalometry in orthodontics. The current possibilities of Cepha 3DT software].

A 3D cephalometric analysis method from a scanner acquisition, has been developed thanks to a long collaboration between the CIRAD modeling Laboratory and Jacques Treil. The model of skeletal description is based on eight landmarks related to the neuromatrical axis of facial growth (heads of the mallei, supraorbital, suborbital, submental points); it has been abundantly described. The purpose of this work consists in presenting the dentoalveolar level of the analysis.
