The denture is prepared for mechanical fabrication in the Wizard step “Design Denture Base Bottom”. This means that the model is blocked out, so that all areas of the basal denture surface are accessed with the possible travel paths of the milling machine and the denture base does not exceed a blank height of 30 mm. For this reason the milling direction, which is set using the path of insertion, should be selected as perpendicular to the denture base as possible.


There are two ways of setting the basal milling direction:

1. By selecting the “Set insert direction from view” button the path of insertion is set using the current view with a click of the mouse.

2. The path of insertion is determined using visualised arrows by visualising the model from the side and moving the model into the required position using a sphere on the tip of the arrow while keeping the left mouse key pressed.

WarningThe milling direction of the denture base should be at a 90° angle to the horizontal plane to reach as many basal sections as possible during fabrication.

The “Smoothing” slide control is in the area “Denture base bottom properties”. As the model is blocked out in an overall uniform thickness, irregularities of the model surface such as extraction wounds or mucosal folds are transferred to the blocked out area. The Smooth function can be used to define how much these irregularities should be flattened out.
