SonicFill 3rd Party Data
Viscosity change of SonicFill when subjected to sonic vibration
Sonic activation provided by the SonicFill handpiece applies shear stress to the composite, which in turn reduces its viscosity. While all composite
materials display some reduction in viscosity upon exposure to shear stress, the unique formulation of SonicFill allows for a substantial viscosity
drop – almost three times greater than traditional composites such as Premise.
In addition, SonicFill displays a more gradual viscosity buildup compared to traditional composites once the shear stress is removed, briefly
retaining its flowable characteristics to enable excellent adaptation, followed by a gradual viscosity increase yielding an easily sculptable, nonslumping
material.
Evaluation of the effectiveness of different adhesive systems in combination
with SonicFill (Kerr) in Class I cavities
SonicFill composite placed in one bulk increment has excellent margin adaptation utilizing either
a etch&rinse or self etch adhesive. SonicFill has superior marginal integrity than both Filtek Supreme
Plus and Tetric Evo Ceram placed in 2 mm increments. Since both Filtek Supreme Plus and Tetric
Evo Ceram have been in use for several years, it can be concluded that restorations bulk filled with
SonicFill composite will have long term clinical success.
SonicFill Mechanical Properties
SonicFill showed the highest flexural strength of all materials tested. Both the flexural modulus and compressive strength of SonicFill are
comparable or superior to most of the composite materials evaluated. These properties strongly support that SonicFill can withstand high
posterior occlusal forces. Furthermore, SonicFill, along with Premise, displayed the lowest volumetric shrinkage of all materials examined making
it well suited for bulk placement.
SonicFill Flexural Strength
SonicFill restorative composite showed the highest flexural strength of all materials tested. A high flexural strength suggests that the
restoration will not deform and degrade even in a high-stress environment such as a posterior restoration.
SonicFill Volumetric Shrinkage
The volumetric shrinkage of SonicFill is significantly less than most traditional composite materials. Most notably, two products
recommended for bulk filling—SureFil SDR and Quixx—have a higher volumetric shrinkage than SonicFill. Low volumetric shrinkage reduces
the likelihood of the composite pulling away from the tooth surface during the polymerization process, thus reducing the potential for
microleakage and marginal staining.
SonicFill Compressive Strength
The compressive strength of SonicFill composite is higher than most of the restorative materials evaluated in this study. Consequently,
SonicFill will withstand typical posterior occlusal forces resulting in durable, long-lasting restorations.
