19.1.1 Select a block size
Available block sizes are listed in the Blocks section. A
default size is selected and shows in yellow.
To change size click on another size.
If the restoration will not fit into any of the block sizes
available for the selected material, click Settings to select
a different material.
19.1.2 Sprue placement
The default setting for the sprue can be changed, see
section 21.3 “Sprue angle method” on page 111.
To change the location of the sprue on the restoration,
move the placement indicator along the circle that
represents the exterior of the restoration click one of the
arrows. Recommended locations are:
• Anteriors/posteriors: midway between lingual and the
mesial or distal
• Premolars: mesial or distal
• Inlays and Onlays: largest proximal box
NOTE
The sprue connects the restoration and the mandrel.
To ensure the sprue is not positioned on a groove:
5. Rotate and inspect the restoration.
6. Move the sprue towards a flatter area of the restoration.
This is usually near the interproximal, but should not be
put on the contact area unless it is necessary.
7. Carefully position the sprue on inlay and onlay
restorations.
8. Ensure the sprue is not attached to an upper surface.
Deactivate View Model to ensure the sprue is properly
placed.
Occlusal only inlays
Since occlusal only inlays have no external proximal
walls, sprue position can become an issue. There are two
options. The sprue can be placed on the internal aspects,
but this will result in manual adjustment of the internal fit,
which can affect the integrity of the restoration.
