摘要: Abstract Objectives The purpose of this in vitro study was to evaluate the wear six composite resins for veneering crowns compared with human and bovine enamel, tested a dual-axis chewing simulator. Methods Eight specimens different (Targis I + II, Solidex, BelleglassHP, Estenia, Solidex) enamel were prepared. Steatite ceramic balls served as antagonistic specimens. Specimens dynamically loaded simulator 49 N up 1,200,000 loading cycles additional thermal cycling between 5 55 °C. After 120,000, 240,000, 480,000, 840,000 cycles, an impression specimens’ surface specimen taken using polyvinylsiloxane material. substance loss at measured computer-aided laser profilometry. Data analyzed ANOVA Tukey test . Results ultra fine compact filled Solidex BelleglassHP not statistically significantly from that enamel. other showed higher than Significance Comparing crowns, BelleGlassHP
