Clinical Performance of Posterior Composite Tooth Fillings in Adults

Clinical Investigation Of A Bulk Fill Composite In Class II Restorations In Adult Subjects

The purpose of this study is to determine whether a new tooth-colored composite material is effective for load-bearing dental fillings.

In this post-market prospective randomized controlled clinical trial, posterior class II restorations will be evaluated for their clinical performance. The study will investigate the survival and efficacy of a bulk-filled composite resin restorative material for a period of 2 years. The bulk fill composite will be used according to indication and applied in approximal two- or three-surface restorations in permanent teeth.
