No-Compromise Performance

Clinical success with SureFil® SDR® flow Posterior Bulk Fill Flowable Base

Scott C. Dickinson, DMD

Flowable composite resins serve several important functions, including lining Class II proximal boxes, adapting to irregular cavity geometry, repairing bis-acryl provisional restorations, and restoring small non-occlusal bearing lesions.1 They are an essential part of my armamentarium that I use primarily for the lining of Class II interproximal boxes to improve cavity adaptation and marginal seal.

Depending on how the material is used, viscosity may be a variable influencing ease of placement and outcome. For Class V restorations, a more viscous material may be appropriate to prevent slumping or movement of material after placement. However, for placement of flowable resin into a properly isolated Class II interproximal box, a less viscous flowable material with rheology capable of spreading out and adapting without agitation or manipulation is ideal. The SureFil SDR flow Directions for Use state that after placement the material is designed to conform to the cavity shape without further manipulation or use of hand instruments.2 Self-leveling handling, combined with the capability to place increments up to 4 mm can increase efficiency by minimizing steps during the Class II procedure.

Several recent peer-reviewed publications have studied the potential for microleakage and bond strength when using SureFil SDR flow. These studies showed that bulk filling did not compromise the marginal integrity of the gingival floor, and microleakage can be mitigated by using SureFil SDR flow.3,4 Additionally, a recent study found that the use of SureFil SDR flow may improve the bond strength to the gingival walls of Class II cavities compared to conventional composite.5

To work quickly and effectively, I use materials that can provide the best clinical advantage such as SureFil SDR flow. With features such as self-leveling handling, excellent cavity adaptation, bulk placement up to 4 mm, and low polymerization stress, it allows me to achieve consistent positive outcomes for my patients without compromising chairtime or performance.
