«Pterygo-clivus triedre»: three dimensional analysis of stability or variations during growth
Keywords:
cephalometry, growth, three dimensional analysis, reconstruction 3DAbstract
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 orthogonazilation’s step has been realized for every child at two different ages. The reconstruction of the «clivus» straight and «pterygoïde» straights from three views gives the « pterygo-clivus triedre» which stability is studied for time.
