“…With the use of a design support program and databases, basic data processing steps were automatically implemented, and the design time was, therefore, reduced to half a day. Finally, the implant is accurately designed, and only RP implant model is made from which the biocompatible implant is fabricated by RT techniques (Hieu et al, 2002b). Therefore, the total patient treatment cost is minimized.…”

“…In the field of cranioplasty, the skull template was not only used for the modelling of the personalized implant as the design support data, but also for making standardised (cranioplasty) implants (Hieu et al, 2002b). The application of standardised implants for the cranioplasty treatment is the cheap technical solution; it provides surgeons a new surgical aid tool for preparing the implants; especially it is very useful for defect cases where the cosmetics are not highly required such as the ones in the hair-covered area.…”

AbstractDesign methods for medical rapid prototyping (RP) of personalized cranioplasty implants are presented in this paper. These methods are applicable to model cranioplasty implants for all types of the skull defects including beyondmidline and multiple defects. The methods are based on two types of anatomical data, solid bone models (STereoLithography files -STL) and bone slice contours (Initial Graphics Exchange Specification -IGES and StrataSys Layer files -SSL). The bone solids and contours are constructed based on computed tomography scanning data, and these data are generated in medical image processing and STL slicing packages.

Development of Personalized Annuloplasty Rings: Combination of CT Images and CAD-CAM Tools

et al. 2009

Although the use of personalized annuloplasty rings manufactured for each patient according to the size and morphology of their valve complex could be beneficial for the treatment of mitral insufficiency, this possibility has been limited for reasons of time-lines and costs as well as for design and manufacturing difficulties, as has been the case with other personalized implant and prosthetic developments. However, the present quality of medical image capture equipment together with the benefits to be had from computer-aided design and manufacturing technologies (CAD-CAM) and the capabilities furnished by rapid prototyping technologies, present new opportunities for a personalized response to the development of implants and prostheses, the social impact of which could turn out to be highly positive. This paper sets out a personalized development of an annuloplasty ring based on the combined use of information from medical imaging, from CAD-CAM design programs and prototype manufacture using rapid prototyping technologies.

“…The power of these software packages together with their ability to manage information from medical images as a basis for design, means that at present, customized designs, specially for the medical device industry, can be designed in a matter of hours, while comparing alternative designs is also made easier (Hieu, 2002, Harryson, 2007. However, the use of customized designs, products, prostheses or implants has been historically sporadic, practically always the fruit of research projects.…”
