Slot panel
Set Slot
The types of slots supported differ depending on the selected milling machine.
1. Single slot
If you select a milling machine that supports a single slot, you proceed with the milling setup without any slot selection.
2. Multi slot
If you select a milling machine that supports multiple slots, you can select slots and perform milling setup for each slot. When a milling machine that supports multiple slots is selected, the slot panel has two possible states: empty and occupied.
3. Milling setup panel
For each slot, select the prosthesis to be designed and the block, then click the gear icon to open the detailed milling settings.
3.1 Shrink factor
If the material of the selected block is zirconia, the shrink factor menu is enabled and the tool panel is displayed.
Factor type: You can choose the shrink factor type. The available options are: Scale factor, Shrink, Shrink factor, % Scale. The default value is Scale factor.
Value input: Only numbers and decimal points can be entered. Up to 6 digits can be entered.
Scale factor
Determines how much the designed model is enlarged during actual milling. In general, this is a real number greater than 1.
scale = 1 / (1 - shrink%) Example: 20% shrink → 1 / 0.8 = 1.25
Min: 1.00 Max: 1.40
1.25 (based on 20% shrink)
4
% Shrink
Percentage (%) input indicating how much the entire model shrinks after sintering.
%shrink = {1 - (1 / scale factor)} × 100
Min: 0% Max: 30%
20%
2
Shrink factor
Ratio of the size after sintering to the size before shrinkage (less than 1).
shrink factor = 1 / scale factor Example: scale factor 1.25 → shrink factor = 0.8
Min: 0.70 Max: 1.00
0.80
4
% Scale
Enlargement ratio expressed in percent; indicates by what percent the designed model is enlarged.
%scale = (scale factor - 1) × 100 Example: 1.25 → 25%
Min: 0% Max: 30%
25%

3.2 Holder position
Changes the pin holder position of the block.
Center button: When selected, the holder is positioned at the center of the block with respect to its height. This is selected by default. (Left: image)
Top button: When selected, the holder is positioned at the top of the block with respect to its height. (Right: image)
3.3 Placement mode
Reset to default: Resets the prosthesis and pins to their initial positions.
Auto pin positioning: Automatically rearranges the positions of the prosthesis and pins.
3.4 Number of pins
Adjusts the number of pins.
3.5 Parameters
Set the pin diameter and the option to cut pins during machining.
pin diameter 1: Diameter of the portion attached to the prosthesis.
pin diameter 2: Diameter of the portion attached to the slot.
pin cut: Menu to set the amount of pin removal after prosthesis machining. This is always enabled, and the default value is 50%. Spin box step is 1%.
Only numbers can be entered.
Value range: 0–80
Decimals are not allowed.
3.6 Strategy
Defines the tool path generation strategy. This is disabled by default and becomes enabled when the milling machine, prosthesis, block, and shrink factor are all set. Strategies are distinguished based on the tool diameter. The default option uses tools up to 1.0 mm in diameter. The high quality option uses tools down to 0.5 mm or smaller.
3.7 Transform Widget
When you hover the mouse, the transform widget becomes active. You can move and rotate the prosthesis, but resizing is not allowed.
When moving the prosthesis toward the holder direction, a warning is displayed if the holder safety distance is violated.
The entire mesh of the prosthesis changes to a warning color (red). If the holder is also violated, the holder changes to the warning color (red) as well.
