Reconstrção e impressao 3D do neurocranio de cao com o uso de tomografia computadorizada como ferramenta para auxiliar no ensino da anatomia veterinária [Reconstruction and three-dimensional printing (3D) of the neurocranium of a dog from computed tomography used as a tool for anatomy veterinary teaching]

The three-dimensional printer (3D) has been contributing to the learning of anatomy and applied areas of veterinary medicine using an interface that can enhance the knowledge of the anatomy of domestic species in a dynamic way. The present study aimed to use three-dimensional images generated by computed tomography (TC) to obtain digitized images and bone models of the dog skull using a three-dimensional printer. The 3D files were generated from images that were edited in Osirix Lite software. Parts of the bones and anatomical features of the skull were printed on 60% and 100% scales. The results allowed to generate digitalized images and three -dimensional impressions from the tomographies, and in this way a collection of images and printed models was created for studies of the anatomy of the canine species. In addition, the methodology clearly demonstrated the importance of using surgical planning in cases involving procedures involving bone structure impairment. Interactive material and 3D printing with high durability that could be made available for educational purposes has been produced.
