Key Features and Technology

Dual-Cure or Self-Cure Chemistry
Most B&E Core Build-Up materials utilize either dual-cure (light-cure and chemical-cure) or pure self-cure chemistry. This is essential because light cannot penetrate deeply into the complex and shadowed areas of a prepared post space or deep pulp chamber. The chemical-curing component ensures complete and reliable polymerization throughout the entire core mass.

High Compressive Strength
The material is heavily filled and engineered for exceptional compressive strength and rigidity. Its mechanical properties closely mimic natural dentin, enabling it to withstand high occlusal forces and resist fracture under the final crown restoration.

Optimal Handling and Placement
B&E Core Build-Up materials are typically dispensed using an automix syringe or cartridge system, which guarantees a perfectly mixed, bubble-free material. This allows for direct and precise placement into the pulp chamber or around an intracanal post. The material exhibits a stackable, non-slumping consistency, making it easy to sculpt the core form without unwanted flow.

Cutability (Dentin-Like Consistency)
Once cured, the material is formulated to trim and cut with rotary burs in a manner similar to natural dentin. This prevents ditching and grooving, ensuring smooth, accurate margin preparation and seamless transition between the natural tooth structure and the core.

Shade Options
B&E typically offers multiple shade options for enhanced clinical versatility:

• Natural/Aesthetic Shades (e.g., A2, A3): Ideal for all-ceramic or composite crowns to prevent gray discoloration.

• Contrast Shades (e.g., Blue or White): Provide strong visual contrast against natural tooth structure, aiding in clear margin identification during preparation.

Radiopacity
The core material is highly radiopaque, ensuring it is clearly visible on radiographs. This allows the clinician to confirm proper adaptation, integrity, and placement depth after the procedure.
