Erosion of Dental Glass Infiltrated Aluminum Ceramics

Abstract:

Article Preview

The erosion of dental glass infiltrated aluminum ceramics by sandblasting was evaluated. The variations of wear depth, surface roughness and bending strength after blasting were of particular interest. The sandblasting parameters of working pressures, times and erodent size came from routine manufacturing procedures. The results showed the erodent size affects the bending strength and pressure affects mainly the wear depth. The surface roughness increased significantly after sandblasting, but the differentiations with various blasting parameters were not apparent. Fatigue cracking characterized the mechanisms of erosion of dental glass infiltrated ceramics.
