Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) are the gold standard to deliver cross-sectional images of the human body. Furthermore, quite a few image reformatting software have been developed in order to obtain a correct pre operative diagnosis and treatment planning. Selective Laser Sintering (SLS) manufacturing is a relatively new technology that produces physical models through a selective solidification of a variety of fine powders. The technology has gained a great amount of attention, particularly in oral and maxillofacial surgery. We investigated shape accuracy of SLS derived medical models through optical techniques, such as the application of fringe projection techniques. Through the application of a full-field measurement technique, we try to avoid subjective decisions regarding the precise location of bony anatomical landmarks.
