PermaFlo DC, Composite Luting/Restorative Resin Refill, A2

Clinical Overview

PermaFlo DC is a highly filled (≈70 wt %) dual‑cure composite resin engineered for permanent cementation of crowns, bridges, inlays/onlays, endodontic post cementation, and core buildup fabrication. Its low-viscosity, thixotropic consistency flows through small‑orifice tips for precise placement and self‑mixes in the double‑barrel syringe format.

Key Benefits

• Exceptional strength and wear resistance: Highly filled composite delivers durable, long‑lasting performance.
• Ultra-low film thickness (~9 µm): Ensures minimal interfacial gap and optimal seating precision.
• Chemically activated, light‑facilitated cure: Reliable polymerization in areas with limited light access; light‑curing accelerates handling and core build‑ups.
• Radiopaque formula: Easily identifiable on radiographs for follow‑up and quality verification.
• Low polymerization shrinkage: Reduces marginal stress and microleakage risk.
• Broad substrate compatibility: Works with porcelain, lithium disilicate, zirconia, PFM, metal alloys, and composite substrates.

Kit Contents

• 1 × 5 mL dual‑barrel PermaFlo DC syringe (shade A2)
• 20 × mixing tips
• 20 × intraoral delivery tips for precise application

Working & Setting Times

• Working time: Approx. 2 min 30 sec from start of mix until initial handling viscosity.
• Chemical set: Final cure in 5–8 min without light activation.
• Optional light cure: Accelerates provisional tack cure or core build-up stabilization.

Indications

• Permanent cementation of crowns, bridges, inlays, and onlays including ceramic, zirconia, metal, and composite substrates
• Endodontic post cementation and core build-up procedures
• Compatible with both total‑etch and self‑etch adhesive systems (e.g. Peak™ Universal Bond) for predictable bond strength

Instructions for Use

1. Prepare and bond the tooth/prosthesis per adhesive system instructions (e.g. Total‑etch or self‑etch).
2. Attach mixing tip to double‑barrel syringe; dispense back and forth until homogeneous.
3. Load prosthesis from internal depth outward to eliminate air entrapment.
4. Seat restoration fully and tack cure if desired; excess cement may be removed with explorer or floss.
5. If light access allows, cure for 10 sec to start polymerization; allow remainder to chemically set (~5–8 min).
6. For post cementation/core build-up: dispense material into post space, seat post, tack cure, then build core incrementally, light‑curing in between as needed.
7. Remove and discard mixing and delivery tips after use. Ensure full set before final restoration placement.

Summary

Ultradent PermaFlo DC (Shade A2, Ref. 5912) is a versatile dual‑cure composite luting and restorative resin combining high strength, minimal film thickness, and self‑mixing delivery for precision cementation, post cementation, and core build-up workflows. With comprehensive substrate compatibility, radiopacity, and optional light‑facilitated cure, it delivers durable, predictable outcomes in both adhesive and restorative protocols.
