Technique models: an endodontic teaching aid.

Many endodontic techniques are difficult to explain and to understand because the student finds them difficult to visualize. The technique model described above enables the student to visualize the relationship between the canals and surrounding anatomical structures. This model also enables the teacher to prepare and compose a step-by-step procedure; many times this is impossible to do in a clinical case. The technique model is a vivid, simple, and inexpensive way to demonstrate various endodontic procedures, and can be an invaluable tool in endodontic education.
