| Resumo: | This paper describes a system that integrates methods for three-dimensional reconstruction and rapid prototyping techniques, enabling the creation of medical models (biomodels) through tomographic data. These models can be manufactured through processes that are useful in many medical applications such as manufacturing of prostheses, assist in the diagnosis and treatment plan, or even for guiding surgical procedures. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) are two commonly used techniques to capture information of human anatomy. The Rapid Prototyping (RP) is a relatively recent to produce objects with complex shapes technique, being obtained directly through three-dimensional digital data. These solid models are built by adding layers of material, layer by layer. Currently, various manufacturing processes are commercially available, such as modeling and Material Fused Deposition and Stereolithography and Selective Laser Sintering. The research was based on a study of a clinical case of a patient Norte-Riograndense Contra o Câncer (LNRCC), located in Natal / RN, patient in study showed mutilations in the region of the premaxilla, and opening poor mouth resulting from surgery to remove cancer lesions. This article describes the procedures for the acquisition of medical images in DICOM format, the conversion of these files in STL format engineering and finally to make the prosthesis via 3D prototyping |
