EsTemp C&B  is a 1:1 ratio self-curing, bis-acrylic resin purpose-built for provisional crowns and bridges. It combines high compressive and flexural strength with a natural, high-gloss finish that doesn't require polishing, so provisionals look good and hold up for extended wear, including longer bridge spans. Low shrinkage and a low polymerization (setting) temperature help protect the prepared tooth and surrounding tissue during placement, and the cartridge is compatible with standard 1:1 automix dispensing guns already used for VPS impression material — no dedicated delivery gun to buy.
 
Key Benefits
High compressive strength — 300 MPa, outperforming the competitive bis-acrylic materials benchmarked by Spident's R&D team.
Durable enough for long-term provisionals — strong fracture resistance supports extended wear and longer-span bridges without the need for trimming or relining.
Naturally esthetic — Maintains high gloss retention after polishing and has stable shade with minimal visible discoloration, and provides a natural tooth-like appearance, even during provisional use.
Gentle on the prep —Dual-step initiation lowers the shrinkage and polymerization (setting) temperature
Works with equipment you already own — cartridge fits standard 1:1 VPS impression-material dispensers and mixing tips.
 
Indications
Provisional (temporary) crowns and bridges, including extended-wear and long-span cases
Chairside fabrication using the direct or indirect (impression-shell) technique
