Objective: It is intended to observe a precise fit in metal articulator that could be joined to RP model, and report a result so that this can be clinically applied in practice.
Methods: A fit region between resin and metal in articulator is fastened by full polymerization after first flasking in liquid unsaturated polyester. Experimental method is as follows. A resin block is cut by using High Speed Precision Cut-Off, and is polished by using Automatic Specimen Polisher, and then it is cleaned after being put in Ultrasonic Cleaner. With regard to the manufactured specimen, a gap was observed in metal-resin joint by using a scanning electron microscope. Specimens were manufactured by using 50, 60 and 70 series anodized aluminum, 50, 60 and 70 series aluminum plated with electroless nickel, S45C metal plated with chromium, S45C plated with electroless nickel, and Mc nylon.
Results: The bonding gap value between the Resin model and MC Nylon was the lowest, and the gap value be tween the Resin model and Alumium 60 series anodiz ing-treated metal was observed to be high.
Conclusion: It was observed that a gap (50.02±7.44 μm) in joint between resin model and MC Nylon was the smallest and a gap (120.25±11.92 μm) between resin model and 60 series anodized aluminum metal was the biggest.
