The sagittal and anterior position of the hyoid bone is at the origin of the changes in orientation of the palatine laminae. A posterior-anterior movement of this bone allows the tongue to liberate the posterior part of the oral cavity; the palatine laminae rotate forwards and downwards. The opposite case is verified in the same way; the naso-palatine canal(More)
101 children, each of them with two teleradiographies, were selected. The first X-ray was taken at the time of the mixed dentition, the second one, when the permanent dentition was established. The purpose of the research is to show the oscillations of the palatine and mandibular planes, and their link to the movements of the first permanent molars. The(More)
The growth's study, from skull's radiographics, needs the use of superposition's structures. Three X-ray radiographics pictures from the front, from profile and from under are retalling by a soft. This orthogonalization's step has been realized for every child at two different ages. The reconstruction of the "clivus" straight and "pterygoïde" straights from(More)
