GrandioSO Heavy Flow

Consultants’ Comments

  • “I liked the consistency, flows but stackable.”
  • “Good option for Class V restorations where too much flow is a problem.”
  • “I liked the high filler content – may have more wear resistance.”
  • “Shade selection and esthetics were good.”
  • “Labeling on the syringe clearly indicates viscosity and curing time.”
  • “The high viscosity makes it a little more difficult to express from the syringe.”


GrandioSO Heavy Flow is a radiopaque, light-cured, flowable composite that is characterized by its high viscosity and high filler content. It is a universal composite designed to be used in place of a conventional flowable when a higher viscosity is needed. Indications include filling all classes of cavities plus extended fissure sealing; filling V-shaped defects and cervical abrasions; blocking out undercuts; cavity lining and tooth splinting. It is available in new NDT® (Non-dripping Technology) 2-g syringes and 0.25-g caps in 12 shades: A1, A2, A3, A3.5, A4, A5, B1, B2, C2, OA2, BL, and WO. GrandioSO Heavy Flow can be used with all light-curing bonding agents and light cures at 20 to 40 seconds, depending upon the shade used. The introductory syringe kit contains one syringe each in shades A1, A2, A3, A3.5 and WO; shade guide and intraoral tips. GrandioSO Heavy Flow was evaluated by 29 consultants in 806 uses. It received a 96% clinical rating.

Product Features

Consultants liked the consistency and stackability of GrandiSO Heavy Flow. It extrudes without air bubbles and does not ooze out of the syringe after use. Some commented that they believed that the high filler content (83% by weight) would result in improved strength and wear resistance. Shades are accurate to the shade guide, and blending with the tooth is excellent. While the material can be used to fill Class II cavities, some consultants found it difficult to manage in larger restorations. Fifty-nine percent of consultants reported that GrandioSO Heavy Flow was better than their current flowable composite and 31% reported they were equivalent. Eighty-three percent would switch to GrandioSO Heavy Flow and 90% would recommend it.

Clinical Tips

  • Place all secondary anatomy after bulk placement.

  • For better adaptation to the preparation, agitate the tip within the material.

  • Not all shades are available in caps – see package insert.
