Goals and objectives
Despite enthusiasm for the educational potential of the World Wide Web, few dental educators use the new opportunities offered by this medium beyond the presentation of textual information. Based on this observation, we have decided to design our own interactive Web-based 3D crown preparation course. The course objective is to provide dental students with fundamental didactic and technical knowledge to begin preclinical skill development for full crown preparations. The course incorporates a variety of interactive features including images which allow students to examine the dimensions and contours of the burs in comparison to the dimensions and the shape of the crown preparation. QuickDraw 3D allows the direct manipulation of 3D graphical models by the users.
