Captek™ system uses a one of a kind bonding mechanism between the Captek™ materials and porcelain (or composite). The Captek™ porcelain bonder, the UCP has gold and platinum micro-filaments extensions on the Captek™ surface. The micro extensions provide exceptional mechanical bond strength. Captek™ has a pure high noble metal composition, which does not produce any oxides, therefore requires a different method of bonding to porcelain. This Captek™ bonding material replaces the conventional grey oxide layer used for bonding in other PFMs, and surpasses it in its bond strength. UCP creates a bond between the Captek™ coping and porcelain that is unbreakable.
The elasticity of the UCP layer diminishes ceramo-metal stresses caused by COE difference that often accounts for porcelain cracking and chipping.

UCP on Captek™ provides a color background for the final crown that is the closest to a natural tooth, thanks to its goldish tones that closely resembles the color of dentin close to the pulp.
UCP contributes to the Captek™ crowns natural beautiful appearance, with its color and light scattering effect. Light reflecting from a Captek™ crown, gets scattered by the micro-structure of the UCP layer, in a similar way of natural teeth. Light is broken and scattered from natural teeth, by the enamel prisms and dentin tubuli, and by the UCP in Captek™.
