FD Stuttgart 2013 - Recent concepts for bulk filling of posterior cavities
Filling posterior cavities using resin composites has always been a challenging task for dentists looking for a fast and reliable technique.
However, resin composites used in posterior teeth must fulfill a number of requirements such as good mechanical properties (high percentage of fillers), low shrinkage and good degree of conversion. On the other hand, the handling of the composite, its ease of placement and the delivery system of the material in the cavity are of paramount importance. The stickiness of the composite on the instrument and void inclusions are also important problems facing the dentist when placing the first composite layer in the bottom of the cavity.
Today, new bulk filling systems from different companies are available, relying on different technologies such as flowable resin composite, sonic energy or fiber-based resin composite. These systems allow optimal composite packing in one or two layers and good adaptation to cavity walls and adequate time for material sculpturing.
This presentation, will give an overview of new bulk filling systems using well documented clinical cases as well as outlining some important steps to achieve successful posterior restorations using this new technology.
