RESUMO

The use of Rapid Prototyping (RP) technology in medicine has been expanding every day. The medical models, or so-called biomodels, used for surgical planning, are made by PR processes, based on computed tomography medical image processing. This technique allows the surgeon to handle anatomical models of the patient, before running the reconstruction surgery. The RP technology associated with biomodelling has proved to be an exceptional tool for: surgical planning, customized prostheses manufacturing and surgery accomplishment, leading to better functional and aesthetic results, as well as, a reduction of risks and costs involved in this process. This work was developed within Promed Project - Rapid Prototyping in Medicine, at Center for Information Technology Renato Archer - CTI, who attended, between January 2000 and September 2008, a total of 982 patients in need of surgical reconstruction. This work presents a data survey on these patients, classifying them by: gender, age, origin, anatomical regions and biomodel applications. The results of this survey indicated that 98% of cases referred to craniofacial reconstructions, with 86% of these injuries covering one or more thirds of the face. Biomodels were mainly used in reconstructions of bucomaxilar rehabilitation (32%), neoplasias and dysplasias (18%), trauma fractures (13%) and facial disharmonies (9%). The integration of biomaterials and RP is examined in the context of this study, showing possibilities for the use of RP in the direct and indirect construction of customized prostheses, in obtaining scaffolds for anatomical reconstruction and tissue engineering. Examples of surgical planning with the aid of biomodels were included in the text, for elucidating the method of application of this technique
