Flowable Composite

PermaFlo flowable composite is light-cured, highly radiopaque,1 methacrylate-based, and available in eight shades. Its thixotropic properties impart ideal flowability for improved adaptation. PermaFlo composite is 67-68% filled by weight, 42-44% filled by volume,1 with an average particle size of 0.7 µm for superior strength and polishability.1

Technical Details

Thickness and Strength


High-Fill, High-Flow Formula

PermaFlo flowable composite’s high fill and high flow give you the best of both worlds. It is 68% filled for high compressive strength.1 But it’s also highly flowable, making it ideal for metal masking, micro restorations, or as a super-adaptive initial layer beneath composite restorations. Its all-out flow makes it easy to place during restorations, while its maximum fill ensures it stays extra strong.

Eight Shades

PermaFlo flowable composite shades offer superior polishability, and afford excellent translucency for matching, blending, and depth of cure.

“The Donut Technique”

Use PermaFlo flowable composite for the “Donut Technique” to achieve extension of root when retention of clamp would otherwise be difficult or impossible.

Highly Radiopaque

​The flowable composite is highly radiopaque, so you’ll never have to wonder if what you’re seeing is dental material and not tooth structure or caries.






Masking dark colors initially facilitates gorgeous esthetics at the surface.

Metal Masking


Place a thin layer of PermaFlo flowable composite Dentin Opaquer over the exposed metal and light cure for 10 seconds with VALO curing light. For curing lights with output <600 mW/cm2, cure 20 seconds.

Superadaptive Initial Layer

After the bonding agent, apply a thin layer of PermaFlo flowable composite at the gingival margin, proximal box axial margins, and internal line angles to ensure quality adaptation of composite.


Micro Restorative

See Instructions for Use for complete instructions, warnings, and precautions.

Step 1

Small Class I preparation treated with dentin bonding agent. Fill restoration with flowable PermaFlo composite through the Micro 20ga tip.

Step 2

​The flowable composite offers unsurpassed adaptation as it fills from preparation floor up.

Step 3

Finished radiopaque, 0.67 μm hybrid restoration. Ultimate restorative seal!

Pediatric Restorations

See Instructions for Use for complete instructions, warnings, and precautions.

Step 1

​Rampant caries in a 3-year-old.

Step 2

Slow speed and large round bur to remove all caries. Stain with Sable Seek caries indicator to ensure prep is in firm mineral dentin. (Compromise where close to pulp.) Quality tissue management is an absolute here; pack a long #0 or #1 Ultrapak cord soaked in ViscoStat hemostatic agent first.

Step 3

Etch preparations and apply Peak Universal Bond adhesive. Light cure for 10 seconds with VALO curing light. For curing lights with output <600 mW/cm2, cure 20 seconds. Apply a thin first layer of PermaFlo composite to the adhesive layer with the Black Micro 22 ga tip. Light cure.

Step 4

​Apply and cure 1 or 2 additional increments. Quickly finish restorations with finishing burs and abrasive cups.

Step 5

​One year later.


​PermaFlo allows us to restore in so many different situations. The material seems to 'flex' better in those difficult Class V restorations, which serves us and our patients more successfully.

​I literally use PermaFlo on every patient. I love the shades and the way it flows and handles. I use it around my posts, prior to core buildups. The stuff is awesome!

Dr. Ian E. Modestow – Florence, MA

​The opaque PermaFlo shade is a terrific tool for difficult esthetic restorations. It allows me to mask metal when repairing a PFM crown and eliminates the grey hue. I am able to cover dark stains and restore the tooth to its natural beautiful shade.

Frequently Asked Questions

  • How flowable is PermaFlo composite?

    PermaFlo composite is considered to be more flowable than others in its category. A test of light-cured flowable composites shows that even with one of the highest fill rate in its class, PermaFlo flowable composite flows better than any other composite on the market.1
