RESUMO
Three-dimensional (3D) printing technology has advanced for applications in the field of reconstructive surgery. This study reports the application of a comprehensive methodology to obtain an anatomical model, using computed tomography and 3D printing, to treat a patient with cancer who designed a prototype oculopalpebral prosthesis for the reconstruction of the affected area of the face (left eye). A personalized prototype was obtained, which adapted to the face of the person, and improved the aesthetics and quality of life. The applied techniques helped to make definitive prostheses using materials that could be permanent. The training and tests carried out in this study favored the understanding and assimilation of the technology and the possibility of applying it to patients in need of facial prosthetic rehabilitation.
RESUMO
Historically, facial prosthetics have successfully rehabilitated individuals with acquired or congenital anatomical deficiencies of the face. This history includes extensive efforts in research and development to explore best practices in materials, methods, and artisanal techniques. Presently, extraoral maxillofacial rehabilitation is managed by a multiprofessional team that has evolved with a broadened scope of knowledge, skills, and responsibility. This includes the mandatory integration of different professional specialists to cover the bio-psycho-social needs of the patient, systemic health and pathology surveillance, and advanced restorative techniques, which may include 3D technologies. In addition, recent digital workflows allow us to optimize this multidisciplinary integration and reduce the active time of both patients and clinicians, as well as improve the cost-efficiency of the care system, promoting its access to both patients and health systems. This paper discusses factors that affect extraoral maxillofacial rehabilitation's present and future opportunities from teamwork consolidation, techniques utilizing technology, and health systems opportunities.
RESUMO
Background: Prosthetic restorations are made to adapt or attach missing human parts in order to restore function and appearance. Maxillofacial defects connote a greater impact on patients, since the face cannot be concealed, and all the senses of the human body are expressed in it. Therefore, in order to restore the patient's quality of life, they are the ones that require the best possible adaptation to the characteristics of the patients. Methods: For the maxillofacial prostheses to fit patients, they must be personalized for each patient. The NGO "Mais Identidade" is a multidisciplinary team that specializes in the rehabilitation of patients with maxillofacial trauma. They use digital manufacturing as a tool to manufacture personalized maxillofacial prostheses for patients. With the help of the NGO, the following research is conducted with the purpose of evaluating different methods of additive manufacturing, 3D printing, in order to select the equipment that suits the needs of the method used in the manufacture of maxillofacial prostheses. To this end, eyelid models will be manufactured in different additive manufacturing equipment, and these will be evaluated according to their economic, physical, and aesthetic characteristics.
