29.4 Restoration type selection – Crown on a Tibase
The Crown on a Tibase selection can be chosen in the menu in the right panel. This requires the selection of a restoration type, jaw, model, crown, tibase, and antagonist model (optional) (if a user uses maxilla and mandible) and confirming by clicking "Start". Note that it is mandatory to have a scanbody scan for "Crown on Tibase" restoration.
Step 1 – Undercuts. Step 1 is used to define the initial parameters for the crown. The slider can be used for setting the values for the undercut. "Set insert direction from view" is used to set the insert direction according to the current viewing angle in the 3D view. "Reset insert direction" restores the original setting of the insert direction. The "Back" and "Next" buttons are used for moving one step back or forwards in the design flow.
Step 2 – Identify Interproximal Areas. Step 2 is used to select/colour the existing adjacent teeth so the crown can be resized by the software to fit. The interproximal area can be deleted by selecting "Clear Area". Pressing the Shift key and holding the left mouse button will define the interproximal area and create a brown contour around the selection representing the crown and bridge base. By pressing the Ctrl key and left clicking with the mouse, you can remove the selection. The "Tool size" slider is used for brush size selection.
Step 3 – Margin detection. Step 3 detects the tooth margins used for crown creation. Pressing the Shift key and holding the left mouse button allows the margin to be edited.
The Project Margin button projects the curve defined by the user on the deformed tooth.
Step 4 – Tibase editing. Step 4 is used for crown upgrading and the creation of a crown screw channel.
"Crown margin" can be used for setting the crown margin. "Titanium base margin" can be used for setting the base margin. "Crown cement spacer" is an extra space for the glue between the crown and abutment. The create crown screw button creates a hole going through the crown so that the user can access the abutment screw and screw the abutment into the implant.
Step 5 – Crown editing. Step 5 is used for adjusting the created crown. "Add/Remove" is used for the addition/removal of the crown material. "Smooth" smooths the crown surface. "Local reshape" is a tool that deforms the tooth at a local point.
The "Tool size" slider is used for tool size selection, and "Tool strength" defines the strength of the tool. The original values can be restored by clicking on the "Set to Default" button. The relevant checkbox can be used for hiding "Adapt Interproximal Contacts" and "Cut Occlusal Intersection".
