I. BUILDING UP PROCEDURE
A. Anterior / Posterior Veneer Crown (with metal backing)
1. Production of Metal Framework
a) Waxing-up and Casting

beads to the facing surface. Cast in the usual manner and remove retainers in 0.5 mm width around the marginal
veneer surface.

Immediately apply a layer of OPAQUE over retention area and light cure for 1 minute. Repeat this process until the
metal color is masked out.
Note: For irradiation time by the GC's visible light curing unit, refer to the chart given below.

Apply Dentin shades*, building up to the desired thickness. Pre-cure. (In some cases, adjust the shade by Lustre
Paint and light cure for 1 minute.)
*A processing aid like MODELING LIQUID can be used. Use a few drops, a brush or adequate instrument to adapt the pastes.

Progressively thinly apply Lustre Paint (A) in 2-3 mm width around the cervical area as required and light cure for
1 minute.
