Construction of a tridimensional model based on computational tomographies

Objectives: Use tridimensional computational tomographies from historic patients and existent bibliographic models to reconstruct a unique model, using visualization, design and 3D modeling software, that allows future anatomic alterations, and homologues real conditions for a posterior analysis with computational aid.
Methods: Selections of computational CBTC tomographies, for the generation of tridimensional surfaces and sectioning of units of greater solid material density, that allows to homologue anatomic structures according to real and literary parameters, through the insertion of geometric dimensions from different patients in a normalized model, whose superficial mesh allows posterior biomechanical analysis. Also, an insertion of soft tissue units coming from bibliographic existing models is employed, reconditioned and resized for the assembly of the normalized model with the structures obtained from the tomographies.
Results: A tridimensional model that’s compose with anatomic units such as the jaw, the maxilla, soft palate, upper and lower teeth, hyoid bone and the tongue, that allows the integration of new structures and conditions.
Conclusions: A first model has been reconstructed, which assemblies a number of anatomic units on it. This model signifies the generation of the first biomechanical analyzes using it as a base geometry, or its incorporation in visualization software for tridimensional planning. This model also presents simplifications that are expected, in a future, to be diminished, like the inclusion of a greater number of bone structures and soft tissue.
