Abstract
In this chapter, the design and manufacture of a new prosthesis for an ocular cavity is reported. The required models were obtained with a computed axial tomography (CAT) in conjunction with computed aided design (CAD) and engineering codes. Three hundred and three[p' tomography slices were taken in digital format (DICOM). Each slice was processed with Scan IP and Pro/ENGINEER. The main objective of this study is to create a digital model, which can be fixed as a cranial implant, by using of a quick prototyping printer system (dust). This prosthesis was implanted on a patient of the Hospital of the Institute of Security and Social Services for State Workers of the State (ISSSTE). For this purpose, craniumplasty was the surgery technique that was followed. This technological development was based on the obtainment of quick prototypes, which is applied in orthopedics. The clinical case discussed in this chapter is related to a 24-year-old individual. He was treated in the area of maxillofacial and plastic surgery. The traumatism was derived from an impact of bullet on the ocular right region of the cranium. Calcium hydroxyapatite, which is highly biocompatible, was used for this purpose. It is very important to mention that this procedure avoided the employment of bone tissue taken from the ribs of the cranial region. As a result of this research, a 3D personalized orbicular cranium model could be presented in order to be fixed in the patient.
