Bulk fill composites can eliminate the risk of microleakage and polymerization shrinkage in posterior restorations. This modern material also reduces the risk of failed restorations and secondary caries. It can be a challenge to replace a deficient posterior restoration. A clinician will have to recreate the restoration with the right functionality, a tight marginal seal, and esthetic anatomical contours. Conventional incremental layering can make for a faulty marginal seal. Also, air may become trapped between the layers of composite material due to the stress of polymerization shrinkage. In addition, there is an increased risk of secondary caries. Fortunately, bulk-fill dental composites offer an unparalleled alternative. With minimal tooth prep, they allow for an efficient filling procedure that can be shaped for anatomical contours. Therefore, by building a hybrid layer using a suitable bulk fill composite to build posterior restorations with anatomical contours, exceptional esthetics, and the lowest risk.
Successful Posterior Restorations with Bulk Fill
Today’s bulk-fill must display multiple features, including high strength, maximum marginal integrity, low shrinkage stress, superior polishing properties, and aesthetics.
As soon as the hybrid layer is crafted, the bulk-fill is placed into the treatment area. The application of adhesive direct posterior restorations only requires removal of the decayed structure.
Regardless of the material is applied to one or more increments, enough time must be allotted to sculpt and finish the restoration. The aim is always to achieve the most natural looking shape, the best color match and superior durability.
Avoiding Polymerization Shrinkage
Polymerization shrinkage stress can happen as the material polymerizes. To avoid this issue, conventional incremental layering was introduced. But this is a time-consuming technique that involves the risk of air getting trapped between the composite layers.
On the contrary, bulk-fill composites like Tetric EvoCeram are designed specifically to harden in one increment. Bulk fill restorations shorten treatment times and enhance the efficiency of a practice. The moldable composite that delivers a thorough cure in layers up to four millimeters can help dentists avoid the need for incremental layering. A composite like Bulk Fill is a nanohybrid with small particles. The wear resistant material demonstrates low surface roughness and is easy to achieve a high gloss.
