Abstract

Today's ceramic restoration application, despite its popularity gained through esthetical advantages and superior hygienically features, has a fragile structure due to its low tensile strength quality. In the long run, it can lose its endurance against shear and draw strengths that occur while chewing. Dental ceramics are sensitive to microcracks that show up on surfaces. Technical flaws like microcracks and porosity which appears during production and inappropriate thermal dilatation parameters cause mechanical failure in porcelain restoration. To improve mechanical strength of dental ceramics we should have a mechanism to prevent these micro cracks get generate and spread. Ceramic structure should be supported either by metal or substructures more durable which decrease effects of tension strength occurring on surface; either it must directly be strengthened structurally.
