Abstract
|
|
|
|
In this study, to improve the flexure strength of Zirconia, on the Zirconia pellet surface measure the flexure strength to melt or permeate the Alumina (Vita Zahnfabrik, Bad Sachkingen, Germany) of private used In-Cream and observe by Scanning election microscope. In the control group(3Y-TZP group), the average of flexure strength was 1623.7MPa, and in the experimental group(Glass-infiltrated 3Y-TZP group) was 1800.2MPa. As a result of observing the interface between glass and zirconia with a scanning election microscope, it was showed that the glass dissolves to permeate into the surface of zirconia, so filled the zirconia with particles.
