Disposable plastic impression trays are made from rigid plastic that provides stability for precise impressions and smooth plastic edges for greater patient comfort. These plastic impression trays are made of a strong, rigid material that aids in the generation of consistent, distortion-free impressions. Compatible with a wide range of impression materials, impression trays offer a system of holes and perforations to optimize flow and retention of materials. The disposable, pre-shaped trays can be easily trimmed or flame softened to adjust for a custom fit. Non-slip grips offer easy, clean removal.
