3M ESPE Filtek Bulk Fill Flowable Restorative capsules are a low-viscosity, light-activated composite resin designed for fast, deep posterior restorations. They feature a 4mm depth of cure, low polymerization stress, and can be safely warmed to 70°C for injection molding. [1, 2, 3, 4]
Key Features & Benefits
- Bulk Fill Capability: Cures up to a depth of 4mm, reducing the need for incremental layer placement.
- Low Shrinkage Stress: Specialized monomer and filler blend minimizes polymerization stress.
- Low Viscosity: Flows easily for precise adaptation to deep cavity walls with minimal instrumentation.
- Warming Tolerance: Capsules can be warmed up to 70°C for up to one hour to support injection-molding techniques.
Technical & Composition Details
- Resin Matrix: Contains bis-GMA, UDMA, bis-EMA(6), and Procrylat resins.
- Filler System: Combination of zirconia/silica (0.01–3.5µm) and ytterbium trifluoride (0.1–5.0µm).
- Filler Loading: Approximately 64.5% by weight (42.5% by volume).
- Available Shades: Universal (U), A1, A2, and A3. [1]
Indications for Use
- Base layer under Class I and II direct restorations
- Low-stress liner beneath direct restorative materials
- Restoration of minimally invasive cavities (small, non-stress-bearing occlusal areas)
- Class III and V restorations
- Undercut blockouts and small enamel defect repairs [1]
