Abstract

La présente invention concerne un procédé permettant de construire un modèle de prévisualisation orthopédique et un modèle d'implant. Ledit procédé permet à des médecins d'affiner le modèle craniofacial par le biais d'un dispositif d'affichage, tout en permettant à des patients de prévisualiser l'effet de la chirurgie esthétique craniofaciale, réduisant ainsi considérablement les litiges entre médecins et patients, et permet de préparer l'implant le plus approprié pour le patient selon les modèles, ce qui permet d'améliorer considérablement la satisfaction vis-à-vis de l'intervention chirurgicale. Le procédé utilise le balayage craniofacial pour obtenir un contour craniofacial interne et un premier contour craniofacial externe, puis utilise le balayage craniofacial pour obtenir un second contour craniofacial externe, forme un contour de chevauchement par chevauchement du premier contour craniofacial externe et du second contour craniofacial externe de manière à construire un modèle craniofacial et à former une zone de contour d'ajustement entre le contour craniofacial interne et le contour de chevauchement, et forme ensuite une cavité entre la zone de contour d'ajustement et le contour craniofacial interne par étirement de la zone de contour d'ajustement, et crée un modèle craniofacial ajusté en fonction de la zone de contour d'ajustement, du contour craniofacial interne et de la cavité et crée finalement un modèle d'implant par capture des données tridimensionnelles de la cavité.
