Material
The ceramic is based on glass that contains latent nucleating agents. 
 In a process comprising several stages, controlled crystallisation is used to produce leucite crystals, measuring a few microns, in the glass matrix

 The semi-finished product or leucite-reinforced ceramic powder is pressed into ingots and sintered. These ingots are the basic components from which dental technicians press restorations. 

Advantages
     Outstanding esthetics 

     For perfect integration into the natural environment. For restorations to blend       with natural      teeth. 

     Excellent fit because of new thermoplastic processing 
     For accurately fitting restorations with optimum marginal seal. 

     Very strong crown, veneers, and inlays/onlays 
     For long-lasting restorations on which patients can rely. 

     Biocompatible ceramic material 
     For avoiding gingival trauma and adverse reactions.
