CLEARFIL AP-X FLOW

• High filler loading: approx. 81 wt% (≈62 vol%) filler content, making it unusually heavily loaded for a flowable composite.

• Flowable consistency: Good adaptation to cavity walls, easy placement in tricky areas, while maintaining composite strength.

• Low polymerization shrinkage: The technology used (Nano-Dispersion Technology for filler treatment) helps minimise shrinkage and stress on cavity walls.

• High radiopacity: Allows clear distinction on X-rays and better monitoring of margins.

• Versatile usage: Though a “flow” version, its mechanical properties allow it to be used in a broader range of indications than typical flowables—though always check manufacturer’s instructions.

⚙️ Technical Specifications

Here are some of the available specs:

• Filler loading: ~81 wt% (≈62 vol%) for the AP-X Flow version.

• Indicated as “super-filled flowable composite resin” with mechanical properties comparable to many universal composites.

• Uses Kuraray’s “Nano Dispersion Technology” for filler treatment for improved mechanical performance.

• Radiopacity and low shrinkage emphasised (though exact numerical shrinkage value for AP-X Flow may need brochure) — the standard AP-X (non-flow) reports shrinkage ~1.9% in some materials; while the flow version emphasises “very low polymerization shrinkage”.

📝 Clinical Notes & Considerations

• Because of the high filler content and flowability, it may serve as a flowable base or for smaller restorations with good strength — but for large bulk posterior restorations you still may want a high-viscosity universal composite layer on top, depending on load.

• Good adhesion to cavity walls, good adaptation due to flowable nature (helpful in margins, irregular surfaces).

• Ensure you use proper bonding protocol (adhesive system compatible with Kuraray’s composite lineup).

• Ensure light-cure equipment has sufficient output and curing time given the filler load and depth of placement.

• In esthetic zones, check the shade matching and translucency — while the flow variant offers strength and handling, aesthetic nuance (layering, shade matching) still matter
