  • Method, device and computer product for making an individual model of a jaw-bone
    Patent number: 7383163
    Abstract: The invention relates to a method, a device and a computer software for making an individual model of a jawbone, which are particularly useful in the development of dental implants or pre-operative planning of implants. The method comprises the following steps: making a tomogram of a jawbone perpendicular to the longitudinal axis of the jawbone; determining the boundary of the jawbone and the surrounding tissue and the boundary between the compact and spongiosal portion of the jawbone; transforming said boundaries into a two-dimensional profile; and extruding the two-dimensional profile into a three-dimensional volume body model of the jawbone. The volume body model of the jawbone may be combined with the volume body model of an implant and then transformed into a finite element model.

  • Method, device and computer program product for generating a three-dimensional model
    Publication number: 20060098008
    Abstract: To create a three-dimensional model for a tangible existing object, the object in question is first digitized to generate a network model of the object. The network model is then divided into bilinear surface elements, which are finally reunited to form a surface or volume model. A finite element model can be created from said surface or volume model by CAD/FEM coupling. The generated models are not only accurate, but also their creation requires a relatively short computational time.
