1. PREPARING MASTER MODEL 2. WAX-UP
Prepare the master model in the
usual manner using GC Fujirock EP.
Margins pencilled in red. Underlying wax colour acts as a depth
guide. Scribe 1 mm from incisal and proximal
areas, establishing where metal
casting limits will be. Using a wax
bur or instrument, remove 1 mm
depth of wax incisal/lingual.
Use GC Exaflex Putty for making a
silicon impression index. Remove excess of silicon incisally to
an angle of 45°. This silicon index
is later used in building up Dentin
and Enamel.
4.MAKING CASTINGS
Wax up die with GC Inlay Wax. Retention Beads II SSS (particle
size: 100μ) enhance mechanical
bond strength between casting and
GC GRADIA composite veneer.
Used in combination with
GC Metalprimer II bonding agent. Apply a thin layer of Adhesive II for
GC Retention Beads II SSS.
Let surface dry and become tacky.
Sprinkle a layer of GC Retention
Beads II SSS evenly over wax
surface. Sprue and invest using a GC
phosphate bonded investment and
cast in a normal way.
5. COMPOSITE BUILD-UP PROCEDURE
12
Apply GC Multisep to the master die.
Use different coloured wax in order
to easily identify the thickness of wax
during veneer cut-out.
Fully contour the wax-up.
