  • The translucency of Polymethyl Methacrylate (PMMA) in fabricating indirect restorations especially in provisional crowns is well linked to aesthetic demands and may be influenced through filler reinforcements. The purpose of this study is to evaluate the translucency of PMMA reinforced with ZrO₂-Al₂O₃-SiO₂ filler system in influencing aesthetics features of the crown.
    A total of 18 samples of PMMA, fabricated with a heat cure acrylic resin (De Trey® Stellon C) in six groups of threes respectively from a controlled (A) and different concentrations at 7% (B), 9% (C), 11% (D), 13% (E) and 15% (F) reinforced with ZrO₂-Al₂O₃-SiO₂ filler system groups. Each sample was made in disc forms with diameter and thickness of (8mm × 3mm). Samples were tested using a UV-VIS Spectrophotometer.
    Results showed the highest total average of transluscency for group C at 9% concentration (0.44946λ) and the lowest group F at 15% concentration (0.42803λ). Statistically, there were no significant differences (α > 0.01) among the groups of PMMA with different concentrations and controlled.
    It can be concluded that the different concentration of ZrO₂-Al₂O₃-SiO₂ filler exhibits an erratic influence of translucency.
