Abstract

The purpose of this research was to evaluate ceramics reinforced with thin metal wires, The results could be applied to evaluate the mechanical properties of in fabricating ceramic crowns and bridges. The wires used in the study were Platinum of 0.025 mm, 0.0508 mm, 0.1 mm and Titanium of 0.127 mm diameters. The ingot used was for staining technique. One or two wires were inserted into the ceramics and the specimens were observed with dental X-rays. The results obtained in this study were as follows: 1.The commonly observed phenomenon was that the wires inserted were pushed away to the peripherally, regardless of types diameter, or numbers of wires. 2.In some Empress specimen the wire was observed to be loosed and cut off.
