Uso de planejamento virtual e biomodelo para reconstrução esquelética tridimencional da calota craniana

Abstract

Reconstruction of the skullcap is a mandatory surgical procedure in all patients who have suffered traumatic loss of segments of the skull. There are great challenges to redo or remodel an anatomical region with peculiar characteristics and contours. There are several treatment possibilities for the resolution of flaws in the skullcap that begins with the bone autograft, reaching the use of biocompatible materials for closure with a good aesthetic outline of the lesions. The objective of this work was to develop a protocol for a virtual manufacture of customized and biocompatible skull caps for printing on titanium. For this, we created a flowchart that starts with the initial assessment of patients with traumatic skullcap failures, performing computed tomography with pre-defined parameters and transferring these images to free software that work with the information from the DICOM to STL tomographic images. Through these programs it is ¨treatments¨ of the reconstructed images to isolate the cranial fault and then a solid virtual object is created, which symbolizes the cranial defect exactly. The cap then receives a mesh that has on its surface units required by free software in this work. Therefore, a customized virtual prototype is created for the treatment of acquired defects in the skullcap.
