    Natural monochromatic tooth colored crowns which can mask discoloration of arrested caries.

  • Self adapt technology

    The crowns bend at the area of high occlusion and self-adapt to new occlusion

  • Radio-opaque

    The crown borders are radio opaque and walls look radio lucent in the radiograph making the evaluation of direct and indirect pulp capping possible.

  • Durable

    Good abrasion resistance and load bearing capacity. 

  • Rough cementing surface

    The inner surface is sand blasted for better retention.

  • Esthetic Laser marking

    Clinically the laser marking is not visible as it is done on cementing surface and looks natural in patience oral cavity.
