[ 1 ] - مقایسه استحکام باند دندان‌های کامپوزیتی و آکریلی به آکریل‌های بیس دنچر گرماپخت و خود به خود پلیمریزه شونده
Background and Aims: Failure of bonding between artificial teeth and denture base material is a considerable problem for patients who wear dentures. Because of the cost of denture repair and the expensive price of foreign artificial teeth, this study was designed to compare the bond strength of composite and acrylic artificial teeth with heat-cured and auto-polymerized denture base resins.Mater...
[ 2 ] - مقایسه مقاومت به شکست بریج‌های سه واحدی Full coverage خلفی FRC و تمام سرامیکی زیرکونیا
Background and Aims: Metal-free and fiber-reinforced composite (FRC) restorations have drawn considerable attention and interest in recent years for restoring in the posterior area due to their improved esthetics. Fracture resistance is one of the most important mechanical properties of materials because of 500-600 N load of occlusion. The restorations should tolerate this load. The purpose of ...
[ 3 ] - Effect of Laser Irradiation on Bond Strength of Zirconia Ceramic to Self-Adhesive Resin Cement
Background and Aim: Bonding of zirconia to resin cement is challenging, and the zirconia surface requires surface treatment to yield an acceptable bond strength. This study aimed to evaluate the effect of different surface treatments on the bond strength of zirconia to a resin cement. Materials and Methods: In this in-vitro experimental study, 60 zirconia discs measuring 12 mm in diameter an...
