Methods: Enlarged plaster teeth (scale 10:1) were scanned rotary and from a single plane using LPX-1200 Picza Laser Scanner. Resulted files were imported in LeiosMesh, where the point clouds from the teeth surfaces were cleaned and assembled. These points were used to extrapolate the shape of the objects, in order to create continuous surfaces by reconstruction. The collected data were used to construct three dimensional models using Rhinoceros NURBS modeling program. The models were reduced to the natural size in order to obtain a normal size of the teeth. Surfaces and solids were generated. These solids were used as a support for further modeling of prosthetic restorations. Resulted objects were exported in ANSYS finite element analysis software, to be used for structural simulations.
Results: Generated stresses were calculated numerically and plotted graphically. Results were displayed as colored stress contour plots to identify regions of different stress concentrations.
Conclusions: Three-dimensional reconstructions after 3D scanings, in order to obtain accurate models, can be used for numerical simulations of the teeth and dental restorations. (ID_1264)
