Premier Dental has expanded its restorative portfolio with the launch of StackFlow™ Injectable Light-Cured Composite, a next-generation flowable composite designed to provide clinicians with excellent handling, precise placement, and the strength required for a wide range of restorative procedures.
Why Was StackFlow™ Developed?
Stacks when you want. Flows when you need
Flowable composites are valued for their adaptability and ease of placement, but clinicians often face challenges such as slumping, air entrapment, or inadequate mechanical strength. StackFlow™ aims to overcome these limitations by combining controlled flow with the durability of a conventional restorative composite.
Key Features of StackFlow™
Thixotropic Handling
One of StackFlow’s standout characteristics is its thixotropic behavior. The material remains stable after placement, reducing slumping, but flows smoothly when manipulated with an instrument. This provides better control during restorative procedures and improves adaptation to cavity walls.
Advanced Nanofiller Technology
StackFlow incorporates nanofillers treated with a proprietary hydrophobic silane surface technology. This treatment enhances filler dispersion and strengthens the bond between the resin matrix and fillers, contributing to improved handling characteristics and greater mechanical integrity. (
Strength Comparable to Conventional Composites
Unlike many traditional flowable composites, StackFlow is engineered to provide mechanical strength comparable to conventional restorative composites, making it suitable for restorations that require both easy placement and long-term durability.
Excellent Polishability
The composite is designed to polish easily, producing a smooth, glossy finish that helps maintain long-term esthetics and supports natural-looking restorations.
Zero-Bubble Syringe Design
Premier has also introduced a zero-bubble syringe tip, intended to minimize air entrapment during dispensing while reducing material oozing and waste. This feature helps improve restoration quality and enhances clinical efficiency.
Potential Clinical Applications
Based on its handling characteristics and mechanical properties, StackFlow™ is expected to be useful for:
- Small Class I, III, and V restorations
- Minimally invasive cavity preparations
- Liner or base beneath composite restorations
- Repair of composite restorations
- Pit and fissure sealing where appropriate
- Areas requiring precise material adaptation and controlled placement
Final indications should always follow the manufacturer’s instructions for use.
A Focus on Clinical Efficiency
According to Premier Dental, StackFlow™ was developed to simplify restorative workflows while maintaining predictable clinical performance. The combination of controlled handling, high strength, esthetic polishability, and improved dispensing technology is intended to help clinicians perform restorations more efficiently without compromising quality.
Looking Ahead
Modern restorative dentistry increasingly demands materials that balance handling, esthetics, and durability. With the introduction of StackFlow™, Premier Dental continues to expand its restorative materials portfolio, offering clinicians another option for injectable composite procedures where precision and efficiency are essential.
As restorative materials continue to evolve, innovations such as advanced nanofiller technology, optimized rheology, and improved delivery systems may further enhance the predictability and longevity of adhesive restorations.
