Visualisation and reconstruction in dentistry

Visualisation in the field of dentistry has not, thus far, reached the same development as other medical fields. Potential applications of visualisation techniques in this area, however, are many, ranging from educational displays to training for delicate procedures. This paper reports on the investigation of techniques for handling 3D models of teeth, aiming at the investigation of dental structures. An algorithm was implemented for this purpose, which reconstructs 3D teeth models from 2D contour slices. Results employing various data sets are presented, including the output of VRML models for exploration.
