Working with Touch Designer

Help Topics

Touch Designer allows you to change the shape of each line angle of the incisors, the shape of the cuspid, and the relative length of the lateral incisors all independently of one another.  Before beginning, it is important for you to become familiar with the meaning of the symbols on each button and to understand what they do.

Cuspid Shapes buttons:

The symbols on these buttons are the most obvious. The text in each button describes the shape of the cuspid that will result when the button is tapped.

Smile Line Character buttons:

These buttons control the relative length of the lateral incisors.  The symbols on the buttons are numbers from 1 through 4.  Tapping 1 will morph the lateral incisor to the same length as the central incisor and cuspid.  Tapping 4 will morph the lateral incisor to a significantly short appearance.  2 and 3 will be various lengths along the continuum between 1 and 4.

Incisor Shapes buttons:

The buttons for the incisor shapes are separated into two rows.  The top row is to define the shape of the central incisor and the bottom row is to define the shape of the lateral incisor.  The symbols on the buttons designate the shape of the incisal line angles:

S = Square shape, the line angle approaches 90 degrees
C = Curved shape, the line angle is slightly rounded
R = Round shape, the line angle is moderately rounded

These symbols are combined in groups of two to define, in this order, both the mesial and distal line angles of the incisor.

For example, the symbol SC in a button means that the mesial line angle is Square and the distal line angle is Curved.

As further example, if you want to change a central incisor that is currently defined by the SC (Square-Curved) button to a more rounded distal line angle, leaving the mesial line angle as it is, look for the SR (Square-Round) symbol.

Conversely if you want to change the SC incisor to show a more curved mesial line angle, leaving the distal line angle as it is, look for the CC (Curved-Curved) symbol.  In this way you can specifically change one element of any tooth at any given time.

Now that you understand the symbols used in Touch Designer lets begin:

    1. Tap the Touch Designer button located on the main menu at the bottom of any screen.
    2. The Touch Designer opens with the default Smile Design Code selection of F1-1.  Note that all currently selected buttons are color coded blue.

    1. At any time you can tap the Key button located at the upper left corner of the screen.  The Key gives you information about the various designators for Cuspid Shape, Incisor Shape Group, and Smile line Character.

 

    1. At any time you can tap the Information icon (to the right of the Smile Design code box) to view detailed information about the chosen Smile Design.

 

    1. With the default Smile Design open point out the characteristics of the smile.  Point to the mesial and distal of each incisor, the shape of the cuspid, and the effect the length of the lateral incisors has on the smile.Demonstrate how changing the length of the lateral incisor effects the look of the smile by tapping the Smile Line Character buttons.  Note, the buttons will change color as you change selections.
    2. This will usually stimulate your patient into telling you what they like and don’t like about the design.  If not, ask your patient what they like and do not like about the design.  Have the patient be specific, you or the patient should confirm the exact area being discussing, by pointing to the spot.  Immediately make the changes that they talk about.The great benefit of the Smile Guide Touch is that only the specific element you want to change, will change, while all other elements remain constant.  You will find that the requested change may draw attention to other areas that will then need modification.  This process is the evolution of the patient’s esthetic choice and is our goal, so go with it, follow where the patient leads.Because the changes are subtle you will want to draw your patient’s attention to the exact location the change will occur by literally pointing to it, then you may need to change back and forth between changes to emphasize what is happening.
        a. Tap the Flat, Pointed or Round Cuspid Shape buttons to change the shape of the cuspids without altering the look of the 4 incisors.

b. To change the shape of the central incisors note the designator buttons for the central incisors (The top row of buttons in the Incisor Shape section).  If you want the central incisors to be square on the mesial incisal line angle and curved on the distal incisal line angle tap the SC (S for square and C for curved) button.  If the patient then requests to see the central incisor more rounded (on the distal), tap the SR button (Note that the mesial will stay Square and the distal will change to Round).

Notice also that as you tap different central incisor buttons certain lateral incisor buttons are allowed (grey) while others are not allowed (green).  Your selected button will be blue.

c. To change the shape of the lateral incisors note the designator buttons for the lateral incisors (The lower row of buttons in the Incisor Shape section).  Select the button that corresponds to the mesial and distal incisal line angle shapes that you want to show.  Alter the selections based on your patients feedback as the design forms.

As you change the shape of the teeth, you will notice that other characteristics will need to be altered when combined with new selections.  Make these changes until you meet your patient’s esthetic desires.

  1. When you and your patient agree on a smile design, note the Smile Design Code in the box at the upper right.  Tap the Information button if you wish to see a detailed description of the Code.
  2. To transfer your Smile Design to the Smile Design Rx page (Pro version only) , tap the Create Rx button located at the upper right corner of the screen.  DO NOT tap the Smile Design Rx option on the main menu located at the bottom of the screen.  You will loose your chosen Code if you tap this option.
