[A new edentulous model maintained at body temperature].

We have produced a new edentulous model, which is maintained at the human body temperature, for higher grade model practice and pre-clinical education. A soft material, its thickness based on the value of the oral mucosa, covers the surface of this model. It takes 4 minutes to reach the body temperature after turning on the switch, and it consumed about 9 watts per hour. This new model is useful for teaching clinical characteristics of impression materials in which the setting time is influenced by the temperature. Improvements are under consideration to fit some thermal and pressure sensors to the buccal and labial parts to make a more sophisticated patient simulator.
