Abstract

''método para digitalizar objetos dento-maxilo-faciais'', a presente invenção se refere-se a um método para capturar a forma de um objeto dento-maxilo-facial por dados de imagem volumétrica do objeto dento-maxilo-facial. o método compreende as etapas de: a) realizar uma segmentação dos sados de imagem volumétrica com pelo menos um parâmetro de segmentação calculado indicativo da distinção entre o objeto dento-maxilo-facial e o seu fundo e derivado de um procedimento de calibração, e b) capturar a forma do objeto dento-maxilo-facial a partir dos dados de imagem volumétrica segmentados.
