Imagine creating a detailed matrix for a custom temporary in less than a minute without messy impression materials or trays. TempTabs —TrueBlue Thermoplastic Impression Tabs soften in hot water or flame to a blue translucent malleable material that conforms instantly to occlusal surfaces up to three units wide — no taste, no odor, no mixing and no distortion. As they cool, they harden into detailed, firm yet flexible opaque matrices for use with all provisional crown and bridge materials. More accurate, easier and less expensive than putty, alginate or wax. "Keys in" better than all other impression materials. And TempTab impressions are dimensionally stable — save them for re-use in case a temporary crown should break. TempTabs may also be used for quick bite registration and to add rigidity to flexible three-way impression trays. Each oval tab is 1"L x 5/8"W x 1/8"D. 72 tabs per box.
