| “Flowables” are more than just fluid dental composite – they’re incredibly versatile materials that present many restorative opportunities. We’ve compiled a list of tips for success to help you get the most out of your flowable restoratives. How to “go with the flow” when doing a composite restoration.  Make sure your delivery method delivers One of the biggest complaints that clinicians have about flowables are the bubbles that appear during dispensing. These tiny voids can be hard to see and difficult to get rid of once in the prep and can cause: staining optical defects microleakage and limit the lifetime of the restoration. There are ways to reduce bubbles, including re-etching, vertical storage, or incremental placement and filling of voids with additional composite. But each requires additional, time-consuming steps. A better solution may be a different delivery method. The innovative syringe designed for 3M™ Filtek™ Supreme Flowable Restorative, https://shop.henryschein.co.za/shop?search=filtek%20supreme and 3M™ Filtek™ Bulk Fill Flowable Restorative https://shop.henryschein.co.za/shop?search=filtek%20bulkfill%20flowable is engineered to eliminate bubbles and run-on, while improving handling. The new bendable cannula, now available in three diameters, provides better access in those hard-to-reach places for easier injecting. When your material and delivery method work together like this, it can bring you closer to a bubble-free restoration.  Keep an eye on aesthetics In addition to durability, the ideal flowable composite should provide aesthetic, natural-looking results. But there are many factors that go into matching natural dentition, including: colour translucency fluorescence radiopacity and polish retention – and not every flowable brings the same level of aesthetics to the table. While flowables are available in many shades, they’re often more translucent, less radiopaque, and less fluorescent than their universal counterparts, due to their lower filler content. This limits their usefulness in certain situations.1 However, Solventum’s unique nanotechnology enables refined properties at the nanoscale – resulting in versatile flowables with: high fluorescence radiopacity polish and improved wear rivaling that of some universal composite materials.  Know what fills your flowable First-generation flowables owed their low viscosity to lower filler content. However, reducing filler content can impact physical, mechanical, and especially wear properties. This trade-off is why many clinicians still distrust flowables in load-bearing areas. But flowables have evolved dramatically. Newer materials use different filler particle sizes, shapes and concentrations to improve mechanical properties while maintaining desirable flow characteristics. For example, Filtek Supreme Flowable Restorative https://shop.henryschein.co.za/shop?search=filtek%20supreme features nano-sized filler particles that provide: excellent wear resistance strength polish retention optical properties, and reduced polymerization shrinkage. Keep fillers in mind when selecting your restorative: in addition to flow, they can also affect adaptation, shrinkage stress and durability.  Use for complex preps and minimally invasive treatment As the demand for minimally invasive treatment increases, clinicians are seeking new methods that preserve healthy oral tissue. Flowables lend themselves to this philosophy – their low viscosity allows them to flow into all the nooks and crannies of small, complex cavity preps without sacrificing healthy tissue. By making use of flowables, you can open a door to a new avenue of treatment.  Use as a liner for the base of restorations Because flowables have demonstrated improved cavity adaptation, they’re often used under restorations to seal the margin – helping prevent sensitivity and secondary caries. In fact, studies have shown that using a flowable as a liner can result in less microleakage regardless of whether a conventional or nanofilled composite is used.2 NOTE: Resin Modified Glass Ionomers (RMGIs) are a solid alternative to flowable composites – both can be used successfully to line a restoration.  Choose the right viscosity3 Flowable composites are defined by their low viscosity, which can provide: easier flow more rapid filling improved syringe delivery, and better cavity adaptation. You can count on flowables to be less viscous than your traditional, paste-like dental composite – but they don’t all flow, or perform, the same way. Different clinical situations can require different viscosities of flowable composite. It’s not enough to simply select the most fluid option. If your viscosity is too low, it can translate to: more shrinkage stress reduced mechanical and physical properties run-on or slumping Make sure you’re using the correct viscosity for your case. For example, some materials flow well during extrusion and thicken within the cavity prep, while others “self-level.” Filtek Bulk Fill Flowable Restorative https://shop.henryschein.co.za/shop?search=filtek%20bulkfill%20flowable uses unique chemistry to lower viscosity without increasing polymerization shrinkage.4  Explore new ways to use your flowable Flowables are recommended for many indications – including some you may not expect. Take the time to investigate new ways you can take advantage of their strengths and open doors to improved outcomes. Consider: Bonding orthodontic brackets and retainers Bonding attachments in aligner treatment Abfraction lesions and erosive lesions Repair of small defects Flowables are versatile materials: in addition to improving flow, they can also help streamline your procedures. They’re a valuable tool for your practice – especially if you know your material well enough to take advantage of everything it has to offer. Don’t forget to check the indications From core build-ups to pit and fissure sealants, flowables have been recommended for many indications – but not all. On the flip side, many dental professionals underutilise flowables based on the limitations of early generation products. Modern flowables have come a long way, and may be more versatile than you think. So always double-check your material’s capabilities before choosing – or writing off – a flowable composite.
