ABSTRACT:
A new type of dental impression device is disclosed, which aides in producing more accurate impressions. The device is a spring loaded device which holds a panel flat against the teeth. This panel is custom fabricated to fit against the teeth just below the height of contour. It temporarily yields a flattened surface, masking all of the irregular surfaces beneath it. The dental impression material may then be removed without the distortion caused by the associated stretching over the curves of the teeth.
