Marginal adaptation of indirect composite resin systems in three different base materials

Composite inlays are indicated for large cavities and different approaches have been proposed to improve the adaptationof Class II restorations, including applying base. The purpose of this study was to compare in vitro the marginal adaptation of class II(MOD) composite inlays(Tescera ATL system, Bisco) made with or without bases, having different physical properties. Extracted human lower molars were used for this study. The base was made from Aeliteflo(Bisco), Dyract AP(Bisco) or Fuji II LC improved(GC) respectively and the comtrol group has no base.(omitted)
