摘要: Fatigue as one of the major factors affecting three-body wear resin composites is influenced by mechanical properties matrix. The aim this in vitro study was to determine (ACTA methodology), fracture strength, and Young's modulus four veneering (Artglass old new formula, Vita Zeta LC Composite, Targis) direct restorative composite (Z 100). Furthermore, pure matrices materials tested. results were compared Amalgam reference material. It should be computed whether there exists a correlation between matrix alone. Wear significantly higher than Z100 (13 μm) (14 μm; p < 0.01, Mann-Whitney U-test). Mean strengths indirect ranged from 127.5 MPa (Targis) 71.6 (Vita LC). elastic moduli 2.9 12.8 GPa. rates did not differ significantly. Three-body complex are highly their filler content, particle size distribution, kind particles, shape, silanization Due fact, testing an essential method cannot replaced single material components. © 2004 Wiley Periodicals, Inc.
