Dental thermoformers can be used in dental laboratories to imprint opposing bites as well as to fabricate other dental appliances such as sports mouth guards, bleach trays, and orthodontic devices. An alternative to a vacuum former, thermoformers heat rapidly using an infrared element and then use the heat to form material tightly around the contours of a dental model. Some systems require compressed air, so be sure to plan a suitable location in your laboratory. As with all dental equipment, be sure to choose a reputable vendor and research customer reviews before purchasing your dental thermoformer.
