Ideas for Success with flowable composites
HOW TO “GO WITH THE FLOW”
1. Examine the indications
From core build-ups to pit and fissure sealants, flowable composites have been really helpful for a lot of indications – however not all. At all times double test what your materials is able to earlier than relying on it to carry out in each scenario.
On the flip aspect, many dental professionals underutilize flowable composites based mostly on the constraints of early technology merchandise. However there’s a motive these low-viscosity supplies are advised for practically each indication – they’ve come a good distance of their efficiency since their inception and have improved in practically each approach, together with their versatility. So earlier than writing off a flowable composite as a viable possibility, confirm its capabilities.
2. Select the correct viscosity
Flowable composites are outlined by their low viscosity, which might present simpler stream, extra fast filling, improved syringe supply and higher cavity adaptation. You’ll be able to depend on flowable composites to be much less viscous than your conventional, paste-like composite – however they don’t all stream, or carry out, the identical approach.
Flowables can be found in all kinds of viscosities that may be helpful in many various scientific conditions, and it’s not sufficient to easily choose probably the most fluid possibility. Decrease viscosity can translate to extra shrinkage stress, decreased mechanical and bodily properties, and run-on or slumping. With this in thoughts, be sure to’re utilizing the right viscosity for every scenario or case. For instance, some compositions characteristic thixotropic properties that permit the fabric to stream effectively throughout extrusion and thicken throughout the cavity prep, others “self-level”, whereas but others have utilized novel monomer mixtures to decrease viscosity with out rising polymerization shrinkage.1Take a look at our article to study extra about monomers:
3. Know what fills your flowable
First-generation flowables owed their low viscosity to decrease filler content material. Nonetheless, decreasing filler content material can have a big impact on bodily, mechanical, and particularly put on properties. This trade-off is why many clinicians nonetheless mistrust flowables or are hesitant to make use of them in load-bearing areas.
However as talked about earlier, flowable composites have advanced dramatically in some ways – together with filler composition. Newer supplies use totally different filler particle sizes, shapes and concentrations to enhance mechanical properties whereas sustaining that fascinating low viscosity and associated stream traits. For instance, some present technology flowables characteristic nano-sized filler particles that present wonderful put on resistance, energy, polish retention, and optical properties – all whereas decreasing polymerization shrinkage. Maintain fillers in thoughts when choosing your restorative: along with viscosity, they have an effect on adaptation, shrinkage stress, different rheological results, and sturdiness.

4. Keep watch over esthetics
Along with being robust and wear-resistant, the best flowable composite ought to present esthetic, natural-looking outcomes. However there are a selection of things that go into matching pure dentition, together with shade, translucency, fluorescence, radiopacity and polish retention – and never each flowable brings the identical stage of esthetics to the desk.
Whereas flowables can be found in all kinds of shades designed to breed goal tooth shade, they’ll usually be extra translucent, much less radiopaque and fewer fluorescent than their common composite counterparts, because of their decreased filler content material. This limits their usefulness in sure scientific conditions.2 Nonetheless, the inclusion of nanotechnology has allowed sure producers to handle optical properties on the nanoscale – and supply versatile flowable composites with excessive fluorescence, radiopacity, polish and improved put on rivaling that of some common composite supplies.
5. Use to line the bottom of restorations
As a result of flowable composites have demonstrated improved cavity adaptation, they’re usually used as a liner below composite restorations to seal the margin – which might stop sensitivity and secondary caries. In truth, research have proven that utilizing a flowable as a liner can lead to much less microleakage no matter whether or not a traditional or nanofilled composite is used.3
NOTE: Resin Modified Glass Ionomers (RMGIs) are a strong various to flowable composites – each can be utilized efficiently to line a restoration.
6. Use for tough or advanced preps and minimally invasive therapy
Because the demand for minimally invasive therapy will increase, clinicians are looking for new strategies to deal with circumstances whereas preserving wholesome oral tissue. Flowable composites lend themselves to this philosophy, as their low viscosity permits the fabric to stream into all of the nooks and crannies of small, advanced cavity preps with out unnecessarily sacrificing wholesome tissue. By making use of flowables, you possibly can open a door to a brand new avenue of therapy.
7. Make certain your supply methodology delivers
One of many largest complaints that clinicians have about flowable composites are the bubbles that seem throughout meting out. These tiny voids may cause staining, optical defects, microleakage and restrict the lifetime of the restoration – however they are often exhausting to see and much more tough to do away with as soon as they’re within the prep.
There are numerous totally different really helpful strategies to cut back bubbles, together with re-etching, vertical storage, or incremental placement and filling of voids with further composite. However every requires further, time-consuming steps. A greater resolution could lie in a special supply methodology. Some syringe techniques are designed to eradicate bubbles and materials run-on, whereas enhancing total dealing with traits. Ensuring your materials and supply methodology work collectively will carry you nearer to a bubble-free restoration.
8. Discover new methods to make use of your flowable.
As acknowledged earlier, flowable composites are really helpful for a lot of totally different indications – together with some chances are you’ll not count on. Take the time to analyze new methods to make use of flowable restoratives, easy methods to make the most of their strengths, and the way they’ll open doorways to improved affected person outcomes. Some choices to contemplate:
• Bonding orthodontic brackets and retainers
• Abfraction lesions and erosive lesions
• Restore of small defects
