<span>Although teaching institutions are continually moving towards electronic forms of delivering learning material, a study of first year adult distance chemistry students found that they had developed a successful learning profile based on their present printed learning material and were reluctant to consider the use of alternative methods of delivery. The reasons for this reluctance were explored by developing a Computer Aided Learning program, based on the students existing learning strategies, and offering it as an alternative to printed material. Although many volunteered to use the program only a third of these persevered with its use. Reasons for abandoning the program were generally associated with a fear that they may be wasting their time in having to learn a new method of study. However those that did use the computer program considered it to be a more efficient way of learning than from printed material.</span>

This study explores the application of computer-aided design and manufacture (CAD/CAM) to the process of electronically surveying a scanned dental cast as a prior stage to producing a sacrificial pattern for a removable partial denture (RPD) metal alloy framework. These are designed to retain artificial replacement teeth in the oral cavity. A cast produced from an impression of a patient's mouth was digitally scanned and the data converted to a three-dimensional computer file that could be read by the computer-aided design (CAD) software. Analysis and preparation were carried out in the digital environment according to established dental principles. The CAD software was then used to design the framework and generate a standard triangulation language (STL) file in preparation for its manufacture using rapid prototyping (RP) methods. Several RP methods were subsequently used to produce sacrificial patterns, which were then cast in a chromium-cobalt alloy using conventional methods and assessed for accuracy of fit. This work demonstrates that CAD/CAM techniques can be used for electronic dental cast analysis, preparation, and design of RPD frameworks. It also demonstrates that RP-produced patterns may be successfully cast using conventional methods and that the resulting frameworks can provide a satisfactory fit.
