Practical Procedure
– Fixed, Metal-Supported Restorations
Entirely cover the retention beads with the second Opaquer layer and precure each segment for 20 seconds.

2 nd Opaquer application
apply the second opaquer layer in such a way that the metal framework, and particularly the retention beads, are entirely
covered with opaquer, i.e. as much as required and as little as possible. after that, precure the opaquer for 20 seconds
per segment using the Quick and then polymerize it in the Lumamat 100.
Procedure for the bridge pontic with Pontic Fill
apply the second opaquer layer in such a way that the framework is completely covered and precure each segment for
20 seconds. next, build up the hollowed out space on the bridge pontic to the level of the abutment teeth using Pontic
fill and precure for 40 seconds using the Quick curing light. Subsequently, apply an opaquer layer directly to the
inhibition layer of Pontic fill, precure for 20 seconds and then directly polymerize it in the polymerization appliance.
– To obtain a smooth transition between the metal and composite, thin out the opaquer at the metal margin.
– If a smooth surface is preferred, lightly tap the top of the surface with a spatula.
– Using a probe, check opaquer for complete polymerization in critical areas and cure again as necessary.
