Visualization and Modelling in Dental Implantology

Data Sources

Conventional (CT) and cone beam computer tomography (CBCT) are generally used for 3 dimensional dental imaging. Recent results have controversial results regarding optimization of image characteristics (artifacts reduction versus density resolution) by using CT and CBCT technologies (Humpries et al, 2006, Katsumata et al, 2007). In our studies the patient imaging data are read in from both CT and CBCT sequences and stored as volumetric model (Xoran Technologies: i-CAT 3D Dental Imaging, GE Medical Systems: HiSpeed NX/i). Reslicing algorithm is frequently included to generate slice view in arbitrary cutting plane orientation. Bone surface models are created by isosurface raytracing algorithm or marching cubes algorithm. Mesh surfaces can be imported for adding gips model topography and realistic model of implants. The surface models can be clipped to see interaction of surfaces with volumetric data and visualize the details of interocclusal relationships.
