title: [The marginal adaptation and wear resistance of a fine hybrid composite inlay in vitro].
abstract: A lab and a production batch of a new fine hybrid composite material were tested in adhesive MOD inlays. Using a long term in vitro test the wear resistance of both formulations and the marginal adaptation of the production batch were quantitated. The wear results were compared to the results generated with an amalgam control. The initial marginal adaptation in enamel was excellent totaling 95.9% (occlusal) to 99.5% (axial) of "continuous margin" at the tooth/cement interface. These values slightly decreased after loading to 81.4% (occlusal) and 93.8% (axial), respectively. In dentine however, insufficient marginal qualities were found (32.0% "continuous margin" initial and 18.9% after loading). The adhesion between inlay and composite cement was excellent and load stable. Both composite batches were significantly more wear resistant than the amalgam control and abraded the opposing enamel cusps significantly less than amalgam.
