[Bulk-fill-composites. Modern application technique of direct composites for posterior teeth].

Direct composite restorations in the posterior dentition have become an indispensable element of modern dentistry. The performance of these restoration, even in the masticatory load-bearing posterior region, has been conclusively proven in many clinical studies. This procedure is usually carreid out in an elaborate layering technique. This time-consuming procedure requires an economically sensible fee, corresponding to the effort involved. Aside from the possibilies that highly aesthetic composites offer in the application of polychromatic multiple-layer techniques, there is also a great market demand for the most simple and quick and therefore economical composite-based materials for posterior teeth. These products are offered in the category of bulk-fill composite.
