Tooth Movements Tab

The Tooth Movmenets tab displays a table showing each tooth’s movement in all dimensions in degrees or millimeters relative to its original position in the most recently captured model of tooth positions. The bottom table row, separated from the others by two heavy horizontal lines, shows the amount of intersection or gap between teeth. As you enter or change values in any of the table cells, the model teeth move correspondingly in the treatment planning main window directly above the table. Similarly, if you move the teeth using your cursor in the main window by clicking on a tooth and using its bounding box control, the values in the corresponding cells in the table are updated.

Note: The Palmer Notation system is used to identify teeth: teeth in each quadrant are numbered 1-8 (central incisor to third molar).

Change displacement value in a single cell

To enter a displacement value, follow these steps:

Click Upper or Lower to select the arch you wish to view or adjust.

Tip: You do not have to pinpoint the small button with your cursor. Just click Upper or Lower to make your selection.

Locate the cell of the table that intersects the tooth number with the type of movement needed.
Double click in the cell to highlight the value, and then type a new value in an increment of .1mm or 1 degree. Enter a negative sign in front of the number if appropriate.
OR
Click in the cell and use the up and down arrows to change the value.

Setup Constraint

Use the Setup / Constraint slider controls in the right column to quickly align all teeth in an arch based on the placement of feature points. The SureSmile system has basic knowledge of tooth alignment as defined by the placement of your feature points, and the slider controls on the displacement tabs allow you to manually set how much movement you want to allow. This feature is very useful when starting a treatment simulations, when you want to quickly simulate desired changes in alignment within a specific range of values.

Tip: Since setup /constraint calculations are based on the location of tooth feature points, correct any placement issues before using the Setup / Constraint slider controls. If you want to manually move teeth, set the constraints first and then make additional adjustments.

To constrain values:

Start a Setup Prescription or a simulation.
Go to the displacements tab and click the Upper or Lower option.
Go to far right column of the row for the movement type you want to constrain. Note that the slider control is set be default to the left or zero. This indicates that no deviance from the tooth feature point for this type of movement is performed. To all a range of permitted movement, slide the control to the right. The amount of permitted movement, in either degrees or millimeters, is shown on the right side of the control. When you have specified the amount of movement you want to permit, release the mouse. Note that none of the values in the row exceed the absolute value shown on the slide control. For example if you chose a maximum range of 1 mm for occlusal (+) / gingival (-) movement, none of the values will exceed 1 mm or -1 mm.

Note: If you need to return to previous values, click the Undo button.

Comparison Stage:

To compare tooth displacements at different stages of the treatment plans, follow these steps:

In the Comparison Stage drop-down menu, select another model, such as the previous simulation.
Click the Compare menu to open the palette and click the Comparison icon.

Note: If you are comparing to the reference model, which is typically the therapeutic model, the comparison teeth are blue. If you are comparing to any other model, the comparison teeth are green. If you choose the same model in the Comparison Mode list as was already selected in the list of products, you will not see a comparison in the treatment planning workspace main window.

Naming Conventions for Setups

Each generation of a setup model is called a stage. Each stage corresponds to a version of a setup submitted to SureSmile or saved by the Digital Lab. A naming convention is applied to each stage.

For example, the name Plan 2 [1.2 Digital Lab] [Small OverJet] indicates that the doctor has submitted a setup called Plan 2", and the Digital Lab has returned the model for review with a short description. The name Plan 1 [2.2 Digital Lab] [] indicates that the doctor has submitted a Setup modification and received a modified Setup from the Digital Lab.

The key below explains the naming convention for this example in greater detail.

Part of the Setup Name	Meaning
Plan Name Plan 2 [1.2 Digital Lab] [Small OverJet]	The Setup name begins with the name of the setup prescription. Plans are named "Plan #" by default, where # is incremented for each additional plan created following "Plan 1". The doctor may also rename a plan.
Practice Stage Counter Plan 2 [1.2 Digital Lab] [Small OverJet]	The Practice Stage Counter is the model number of the setup started by the doctor when the setup is submitted to Dentsply Sirona. The first value will be "1." Each time the doctor modifies the model, this number will be incremented to 2, 3, etc.
Digital Lab Stage Counter Plan 2 [1.2 Digital Lab] [Small OverJet]	The Digital Lab Stage Counter is the revision number of the Setup that corresponds to changes made by the Digital Lab per the doctor’s instructions. The Digital Lab may save multiple revisions to depict various scenarios. The first value will be "1." Each time the Digital Lab saves a stage, this number will be incremented to 2, 3, etc.
Creator of Stage Plan 2 [1.2 Digital Lab] [Small OverJet]	One of three values are possible for the Creator of Stage: Practice - the stage was created at the practice (in other words, by the doctor) Digital Lab - the stage was inserted automatically by SureSmile for use by the Digital Lab. Digital Lab Manual - the stage was inserted manually by a Digital Lab Technician, usually to allow the technician to try a different approach while preserving the previous version
Description entered by Digital Lab Plan 2 [1.2 Digital Lab] [Small OverJet]	If the doctor submits multiple setup prescriptions (e.g. Plan 2), the Digital Lab will type a description to help distinguish plans

Displacement Type

Click the Tooth option to calculate movements from the center of each crown. A positive number indicates mesial, buccal/facial or occlusal movement of the crown. A negative number indicates the opposite movements. When moving teeth by entering values in the Displacements tab table, the center of the crown is the point of reference.
Click the Bracket option to calculate movements from the center of each bracket slot.
Click the Cusp Tip option to navigate about the cusp tips axis. When you click this option the cusp tips tooth feature points display. This tool is designed to:1) align teeth without bonded brackets, or2) teeth that have compromised anatomy. This option is also helpful when aligning the torque to the anteriors while maintaining the arch form. It is also useful for applying buccal torque together while maintaining the occlusal plane.

Applying IPR

On the Tooth Movements tab, check the amount of space needed to achieve the target simulation. When IPR is applied, the system displays a negative value for each affected tooth in the Intersection (-)/Gap (+) row in the Displacements tab table. The IPR shown is for the mesial of the affected tooth.

Follow the steps below to enter IPR.

Select the Tooth Movements tab and locate the cell of the tooth chart for which you want to enter a value.
Click in the cell.
Press and hold the Shift key, and click in another cell. For example, select another cell on the same row to add the same IPR value for multiple teeth.

Result: All selected cells are highlighted.

Enter the value you want for all of the highlighted cells by typing the new value or using the Edit Selection controls at the bottom of the tooth chart.

Malocclusion Includes Max. / Mand. Alignment Adjustments

Checked by default in the Tooth Movements tab, because you are focusing on tooth movements. Toggling the check box toggles the tooth displacements just between tooth movements, or tooth movements plus global movements.

Edit Selection:

To apply a displacement value to multiple cells:

Locate the cell of the table that intersects the tooth number with the type of movement needed.
Click the cell to highlight.
Press and hold the Shift key, and click in another cell. For example, select another cell on the same row to achieve the same movement for multiple teeth.
In the Edit Selection box below the chart, type a new value.
OR
Click the small up and down arrows (first set) to change to the number required.
Click the equal button to apply the typed value to the highlighted cells.
OR
Click the large up arrow (second set) to increase the typed value in each of the highlighted cells.
OR
Click the large down arrow to decrease the typed value in each of the highlighted cells.

Clear Spaces/Reset:

To clear all Gaps or intersections in the setup or simulation, click Clear Spaces. All values in the Gap (+) / Intersection (-) row of the table are removed.
To permanently remove all displacement values of your setup or simulation so that you can completely start over, click Reset.

Caution: Use the Reset function as a last resort only. Once you remove these displacement values, they cannot be retrieved. You will have to start your setup or simulation from the beginning.
