Creating new jobs

A job contains all the data required to machine a dental splint: 3D data, base and trim parameters, calculated milling path, etc.

Step 1: Create the job

You create a new job in the overview view of TrimCAM.

1. In the menu bar, select New job.

2. Select Trim line for dental splints.

3. Give the job a name via the input field Name of job:.
   The name may not contain any umlauts or special characters.

4. Select OK.

   • TrimCAM creates the job and the job view automatically opens.

Step 2: Using the job template

The trim, base and material parameters are stored in job templates. In new jobs, the Default template is selected.

• To use a different job template, select the template in the selection list.

   (Optional)Managing job templates

Step 3: Importing the dental arch model

You import the dental arch model as an STL file. You can import single dental arch models or multiple dental arch models for serial machining. In serial machining, you only use files from the same jaw and the same patient.

1. Make sure that the STL files meet the TrimCAM requirements.

    Requirements for STL files

2. Select the machining area Browse.

3. Navigate to the required file(s) in the file browser and select it or them.

4. Select Open.

• The dental arch model is displayed in the 3D display.

3D display

Depending on the machining step, here the dental arch with or without a base, trim line and milling path are visible. You can adjust the 3D display to your needs.

• If you are editing multiple dental arch models, select under Display the dental arch model shown in the 3D display.

• Use the switch at the top left to show or hide specific elements (dental arch, base, trim line and milling path).

• Rotate the 3D preview with a pressed left mouse button.

• Zoom in or zoom out the 3D preview by scrolling the mouse wheel.

• In the icon bar, select among different standard view and advanced display options:

Step 4: (Optional) Import trim lines

TrimCAM offers you the option of importing trim lines from CAD applications. You import the trim line as a PTS file.

1. Make sure that the PTS file(s) meet(s) the following requirements:

   • The first and last points of the trim line must be the same (closed curve).

   • The PTS file and the corresponding STL file must have the same name.

   • The PTS file and the corresponding STL file must be in the same folder.

   • The PTS file and the corresponding STL file must be in the same coordinate system.

2. Under Load trim line, click Browse.

3. Select all desired PTS files.

• TrimCAM loads the PTS files. The Calculate trim line process is no longer necessary.

Step 5: Setting up serial machining

During serial machining, all selected dental arch models are calculated with the same parameters.

• Under Interval for the trim line recalculation, specify how many dental arch models are to be calculated. The last calculated trim line is projected for all other dental arch models.

  Loaded dental arch models are numbered alphabetically by file name.

  Example: Calculation interval = 2

  Model	1	2	3	4	5	6	7	8
  Calculation	Yes	No	Yes	No	Yes	No	Yes	No

  Example: Calculation interval = 3

  Model	1	2	3	4	5	6	7	8
  Calculation	Yes	No	No	Yes	No	No	Yes	No

  When fewer dental arch models are calculated, the calculation is faster. When more dental arch models are calculated, the trim lines for all models are more accurate.

Step 6: Calculate trim line

TrimCAM automatically detects the trim line and adjusts it based on the input values.

1. Enter the distance of the trim line from the gingival margin in the input field Distance of the trim line from the gingival margin [mm].



Example: Distance of 0.5 mm



Example: Distance of 3 mm

2. Permissible inaccuracy of trim line (distance between curve points in mm): Keep the value of 0.7.

3. To trim the dental splint at the posterior molars, activate the option Trim dental splint on posterior molars.

   1. Enter the percentage trim via the value bar shown or the input field Trim [%].

      Rule: The higher the value, the stronger the trim on the dental splint at the posterior molars.

      

      Example: Trim of 0%

      

      Example: Trim of 100%

   2. (Optional) To define a different trim at the right and left, activate the option Asymmetric trim.

      The information at the right and left refer to the standard top view of the dental arch. Activate the top view with the icon .

      

      Example: Trim left of 0%, right of 100%

4. To flatten the trim line, activate the option Level the trim line.

1. Via the value bar shown or the input field, enter the leveling factor on a scale of 0 to 1.7.

   Rule: The higher the value, the flatter the trim line. The lower the value, the more the trim line follows the curve of the gingival margin.

   

   Example: Leveling factor of 0

   

   Example: Leveling factor of 1.7

2. (Optional) To define a deviating leveling factor on the oral dental surfaces, activate the option Deviating leveling factor oral. Via the value bar shown or the input field, enter the deviating leveling factor on a scale of 0 to 1.7.

   

   Example: Leveling factor (global) of 0, deviating leveling factor oral of 1.7

3. (Optional) To level the trim line only from the direction of the interdental spaces (and not from the direction of the gums), activate the option Level the trim line only from the direction of the interdental spaces.

5. To define a deviating distance of the trim line from the gingival margin for the posterior molars, activate the option Deviating distance of trim line at the molars. Enter the deviating distance in the input field shown.

   This option is only visible if the option Trim dental splint on posterior molars is deactivated.

   Rule: The lower the value, the closer the trim line is to the molars.



Example: Distance (global) of 2 mm, deviating distance of 0.5 mm



Example: Distance (global) of 2 mm, deviating distance deactivated

6. Select Execute.

• TrimCAM calculates the trim line and displays it as a red line in the 3D display.

7. If you are not satisfied with the result:

1. Select Reset

2. Adjust the values.

3. Select Execute.

8. Alternative: Manually adjust the trim line.

   1. Select the icon.

   2. Press and hold the left mouse button to move the trim line.

9. Select Next.

• The view for adding the base and the material selection is displayed.

Step 7: Selecting material

1. Select an entry from the Material selection list.

2. Select an entry from the Material strength selection list.

   To activate material thicknesses of 2-5 mm, select the Machine type E3_Splint under Settings.

3. Select the File name option under Label so that the dental arch models are labeled with their file names.

4. Select Execute.

• TrimCAM adds the base and the machine mount and displays it in the 3D display.



 

1. Machine mount

2. Dental arch model

3. Base

5. Select Next.

• The following happens:

1. TrimCAM calculates the job. It is displayed in the job list of the DentalCNC.

2. The STL file for the 3D printout is saved in the corresponding output folder.

6. If you are not satisfied with the result:

1. Select Reset

2. Adjust the values.

3. Select Execute.

Step 8: (Optional)Managing job templates

1. Set the desired parameters.

   • Trim parameters

   • Base and material parameters

2. Give the job template a name via the input field Job template.

3. Select Duplicate.

4. Select Save to save subsequent changes.

5. To select among different job templates, use the selection list.

6. Select Delete to delete the selected job template.
