There are again control points  wich we can move to change the shape. We can move them in, out, up and down.
With the big control point  in the middle you can put the size up and down.
|For a more complex shape, you can additionaly add control points by holding the <STRG> button pressed |
and clicking left on the dotted control line.
Wizard tab: Top
|The movement is restricted by the angle slider  in the wizard window, so it can't be that the shape of the abutment get undercuts.
The shape is always enforced by the angle. With a lower value you got more freedom for your design.
It's also possible to tell the software to enforce a certain space between the anatomy and the abutment with the „Spacing“ slider .
The value which will be applied here set the distance between abutment and occlusal area to the given value.
In the area of mesial, distal, vestibular and oral area it sticks just fifty per cent of the given value.
With activating the checkbox „Distance to anatomy“ , you can visualize the distance between anatomy to the abutment,
the visualization is given on the abutment. The visualization is color coded from red which means low distance and blue high distance.
The highest value is set by the slider „Spacing“.
You can also have a measurement „Distance to abutment“  which visualization is presented on the anatomy.
We also have the option to auto adapt the occlusal area, with the activating of the checkbox  to the anatomic shape.

Wizard tab: Bottom
Within this tab you have the opportunity to correct your design you have made in a fewer step, if needed.

|Mostly the same like screw retained bridge, see section "Generate abutment bottoms - Advanced options" for details.
One important different step - „Milling parameters“
The slider „Min. thickness“  gives you the possibility to set the restriction for minimum thickness of the abutment.
The slider „Ø-Tool“  can be used to set up the diameter of the tool, which is used to mill the crown/coping, also
known as the tool radius compensation. This parameter should be only changed if the supraconstruction will not be produced by CAD/CAM system.
|You even get the best fitting between abutment and supraconstruction, if you mill both parts at the same
time. This is why we fully consider parameters  and  during the design.
If these parameter are set to zero, you will get more freedom in design, but you have the problem that the sharp
edges at the top of the abutment can't be milled, because of the diameter of the tool. You need a radius
compensation in dependence of the tool which is used for milling.
 - Distance to the Screwchannel
This keeps a minimum distance of the abutment to the screw channel. The control
points can't be set closer to the screw channel than this value is.
 - Margin
This is the minimum angle at the margin of the abutment.
