Creating a Post-Surgery Setup without a Treatment Simulation Attached

If you... Then...
selected surgical treatment options during your review of the therapeutic model the plan will automatically have the Surgery tab displayed, and the plan will be named Set-Up Plan 1 (Post-Surgical).
created a post-surgical treatment simulation but did not attach it to the plan make sure you attach the post-surgical treatment simulation now.
(See the help topic Creating One or More Post-Surgery Treatment Simulations for instructions on attaching surgical treatment simulations.)
did not select surgical treatment options during the Therapeutic Model Review, and no Surgical Treatment Simulation has been attached check one of the Surgery options in the Setup Prescription Guide MACROS form under Surgery. The product name changes to Plan 1 (Post-Surgical) and the Surgery tab appears.

Create a post-surgical setup without a treatment simulation attached:

  1. During your review of the therapeutic model, or immediately after approving the therapeutic model, open the MACROS form.
  2. In the Surgery section under Surgery on, check the Upper and/or Lower check boxes as appropriate to enable the Surgery tab.
  3. From the menu bar, click the clock icon to expand the timeline.
  4. Click the New menu and select Setup.

    The new setup is named Post-Surgical.

    Once you click a surgical option, the Max./Mand. Alignment controls on the Global Registration tab are unavailable, and changes must be made on the Surgery tab for each arch selected. If one of the arches is not indicated for surgery, mechanical movements (e.g., for TADs or elastics) can be made as usual on the Global Registration tab for that arch.

  5. Select the Surgery tab.

    The color-coded segment handles are shown on the 3D model. The system default displays one segment per jaw. In the Segment Alignment area under the Surgery tab, the surgical skeletal movement features for the upper and lower jaws are also color-coded.

    Use the Show/Hide Surgical Segments icon on the Tools menu palette to turn on or off the segments.

  6. If you are planning multi-piece surgery,under the Surgery tab, indicate the number of segments in the maxilla or mandible in the surgical segment selection area.
    • Click and drag the surgical cut vertical indicators on the teeth diagram to mark the cuts. The Segment Alignment area is updated to display a tab for each new segment you create. The color-coding for each tab matches each bone segment in the 3D model.
    • You can move the jaw pieces by typing in values in the surgical segment alignment area or by using object navigation in the main window. Use object navigation just as you would to move teeth. Select a jaw segment in the 3D model, and drag the segment handles to the desired position.
    • You can move a single segment and then split it into two or more segments by changing the number or segments on the Surgery tab. The new segments will retain the same adjustment as the original single segment.
  1. Select the following options as needed:

    • Malocclusion includes surgical adjustments – for post-surgical:

      • When checked, the therapeutic model includes planned surgical movements. The tooth displacement values will only include movements due to dental corrections.
      • When unchecked, the therapeutic model does not include planned surgical movements. The tooth displacements will include both dental and skeletal corrections.
    • Show Pre-Surgical – When checked for a Post-Surgical setup, shows the setup dental movements without any skeletal corrections.
    • Reset Pre-Surgical – (Only displayed for Pre-Surgical setups or simulations.) Click to remove all skeletal movements.
    • Hold Teeth – When checked, holds teeth in place, allowing additional surgical movements to be made without changing absolute tooth positions.

    • Reset Segment Position button to clear values in the global movement tabs and return the surgical segments to their original position before you started movements.

    • Use Common Rotation Axis – Check if you want both arches to use a common axis of rotation.

    • Use Condyle Axis – Check to simulate the natural movement of the lower jaw rotating around the condyle axis. When you rotate the bone segment, the axis of rotation is relative to the condyle.
  1. From the Display menu palette, click the Lateral Ceph icon to toggle on/off the combination ceph and left buccal view. This is a toggle on/off view. When toggled on, all other views are linked to and superimposed upon the lateral ceph view.
  2. From the Display menu palette, click the Fade image control icon to open the Fade Image control. Use the slider on the control to  adjust the opacity of the ceph.
  3. (Optional) To set the skeletal horizontal plane, follow these steps:
    1. From the Tools menu palette select the Show/Hide Horizontal and Vertical Facial Axis toolbar icon .  This displays the Skeletal Horizontal Line (a blue line with two end points).
    2. To make adjustments, click a point. It turns pink and the Frankfurt Line box opens. Click and drag the end points of the of the line to the desired locations.
    3. Once points are correctly placed, click Apply to apply and save your changes. The ceph will be adjusted to maintain a set parallel horizontal line. The bounding box will adjust to be parallel to that line.

  4. After completing the surgical movements, perform the dental movements and fill out the MACROS to complete the Post-Surgical setup prescription.

  5. When finished with the setup, go to the Order tab to submit the setup to the Digital Lab.
