Abstract
The purpose of this report is to describe a milling procedure for the fabrication of skull models from 3-D CT data. Data from computer tomographic cuts are transferred to a computer and stored. Model fabrication takes place using high quality styrodur that is shaped with a high speed milling device. This allows the modeling of an individual life size skull in its skeletal as well as in its soft tissue contours. Smaller bone pieces and areas can be enlarged separately up to eight times normal size for better visualization. Planning and simulation of craniofacial surgery in three dimensions is possible, and bone implants or alloplastic biomaterials can be modeled for implantation.
