Which machine is used to make mouth guards and temporary bridges?

The machine used for making mouth guards and temporary bridges is the vacuum former. This device utilizes heat and vacuum pressure to shape thermoplastic materials over a model, allowing for accurate reproduction of the desired dental appliance. The process of heating a plastic sheet and then forming it to the contours of a dental cast under vacuum creates a precise and custom fit, which is essential for both comfort and functionality in mouth guards and temporary bridges.

Other machines mentioned may serve different purposes; for example, a dental vacuum is typically used for suction during procedures, and a mouth guard maker, while it sounds specific, does not denote a distinct machine separate from the vacuum former. The Omnivac is likely associated with suction and not specifically designed for shaping materials like mouth guards or temporary bridges.
