Personal implants for reconstruction of craniofacial harms become more and more important due to their better performance than modelling titanium mesh or alloplastic material during surgical operation. This is due to the good fit in the implant area, reduced surgical time and better cosmetic results. The creating of such implants is a challenging task. In this article structured process workflow with clearly defined steps was introduced. All of the steps were evaluated with solving of clinical case. In this first article the reconstruction from CT-data and 3D modelling of custom implants for the purpose of cranioplasty were reviewed in details.
