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.
