The article refers to the development of several computer programs designed to fulfil the role of teaching aids in relation to the technological aspects of dentistry. The hardware used was a BBC Master computer, this being a deliberate choice, to demonstrate that it is not necessary to have state of the art computer technology in order to produce very satisfactory computer aided technical instruction packages. All the programs were written in BBC Basic. Computer graphics illustrate and simplify dynamic concepts involved in dental technology. The programs having been developed in house proved to be inexpensive, in addition the program structure allows for easy upgrading. An extract from one of the procedures that serves to make up the modules is included to demonstrate the simplicity of the programming and the modular concept of program development.
