Abstract
Biomodels are physical reproductions of anatomical structures of regions or organs of the human body used for diagnosis and surgical planning. The use of tomographic images for generating 3D models and manufacturing of biomodels has been awakening a great interest in the medical area. Besides the creation of biomod models, it is possible, with the use of images, to generate representative computer models, thus enabling several simulations and biomechanical analysis of the region or organ of interest, aiming at the manufacture of customized prosthesis or orthesis. In this work we present the project of a customized implant of the TMJ (Temporomandibular joint), mechanically ordered and manufactured in titanium alloy (Ti6Al4V) by the additive manufacturing process of DMLS (Direct Metal Laser Sintering). Through the model created for the TMJ region, computer simulations of stresses and deformations were performed on the mandible virtually implanted in the patient, considering severe stresses of human mastication applied to the frontal teeth (incisors) of the mandible. With the data from the computer simulations the prosthesis was optimized and analyzed through a conventional analytical design process to verify the fatigue failure resistance. The implant was fabricated in titanium alloy by additive manufacturing and was realized physical simulations of the coupling of the prosthesis in the biomodel of the mandible fabricated by three-dimensional printing of polymeric material.
