The use of composite combinations in posterior teeth

reasons for the limited lifespan of those restorations.2-5 Predominantly in recent years, these inadequacies have been greatly reduced through further developments in the materials of the composite and adhesive systems.6 Nevertheless, the negative effects of polymerisation shrinkage – such as poor marginal integrity, insufficient adherence to the cavity walls or cusp deflections – still represent the greatest problem in composite-based materials.7 Today, hybrid composites or hybrid composites modified with nanoparticles are the material of choice when using a direct restoration technique for the permanent treatment of larger primary carious lesions or the replacement of older, insufficient restorations in the posterior region. Prerequisites are the correct use of the matrix technique and adequate moisture control of the cavity.8 Composites are processed in the incremental layer technique, usually in single increments The use of composite combinations in posterior teeth
