Water and Abrasive Effects on Three-body Wear of Composites

摘要: The degrees of in vitro three-body wear resistance a hybrid, small-particle, and microfilled composite were determined after water storage for up to 24 months. hybrid was the most wear-resistant, while showed wear. no loss as result storage. small-particle decrease only when tested with silicon carbide abrasive. decreased following either soft (CaCO3) or hard (SiC) For all composites, abrasive not capable causing preferential polymer matrix, observed on vivo specimens. Instead, filler particles became flattened, minimal interparticle substance. did cause matrix. All composites absorbed leached during storage, indicating that...
