Independent tests confirm that Prelude has the very high 5 minute and 24 hour bond strengths. It also has the smallest standard deviation,* proving Prelude to be very technique insensitive. Prelude is extremely forgiving in the presence of moisture. Too wet, or too dry is not a concern. Its water/ethanol formulation tolerates an environment that would adversely affect other products.
The remarkably low 5 micron fi lm thickness means fit is not affected and it will not present a radiolucent layer. Bond strengths to cut and un-cut enamel are extremely high. It is ideal for Cerec and other milled systems.
