Abstract:
The lab processing techniques for porcelain can significantly affect strength of a porcelain dental restoration, and thereby, its clinical performance. In this context, a study was done to assess the influence of different rates of cooling on the strength of glaze fired alumina reinforced porcelain. Fracture toughness and microhardness were the parameters used to assess strength. Vickers microhardness indentation was used to quantify fracture toughness and microhardness. And, Image J Analyzer, a software tool was used for measuring the cracks created in the porcelain on indentation. The study also attempts to assess if a change in the medium of cooling, can affect strength. The rapidly cooled groups (both in air and water), had higher strength relative to slow and medium cooled groups.
