Creating new jobs

A job contains all the data required for trimming one or more dental splints: 3D data, base and trim parameters, calculated milling path, etc.

Schritt 1: Create the job

You create a new job in the start page of trimcam.

1. Select New job.

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

3. Select Create.

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

Schritt 2: Importing dental arch models

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.

trimcam can import trim lines from CAD applications to the PTS and ASC file formats.

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

    Requirements for STL files

2. Select in the editing area, under Manage dental arch models.

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

4. (Optional) Select all desired trim line files. Make sure that the trim line file(s) meet(s) the following requirements:

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

   • The following must be identical for the trim line file and the associated STL file:

     • File name

     • Folder

     • Coordinate system

5. Select Open.

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

• (Optional) trimcam loads the trim line files. The Calculate trim line process is no longer necessary.

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 the dental arch model in the editing area that is shown in the 3D display.

• To show or hide certain elements (dental arch, preview of the milled model, trim line and milling path), select .

• Use the slider to adjust the transparency of the dental arch model.

• To adjust the trim line manually, select .

• Rotate the dental arch model by holding down the left mouse button or using the mouse wheel (depending on the setting).

   (Optional) Managing job templates

Schritt 4: Serial machining

trimcam enables series machining for several dental arch models, each representing individual treatment steps for a single patient.

• In the Manage dental arch models area, load all associated dental arch models into the job.

  • Use the control elements to select, move and delete loaded models.

• Specify the desired parameters for the individual dental arch models individually.

   Define machining parameters of the job

Schritt 5: Define machining parameters of the job

trimcam starts the calculation of the job and automatically recognizes the trim line as soon as you have imported the first dental arch model. Please note the following:

• When you change a parameter, the calculation is updated automatically.

  You can set all parameters using a slider or a selection list. You cannot enter numerical values directly.

• You can recognize the status of the selected dental arch model by the progress bar in the editing area.

  

   

• You can switch between the dental arch models of a job to check the status.

• Once a dental arch model has been fully calculated, it is displayed with the base and machine mount in the 3D display. The trim line is shown as a red line.

  

   

  1. Machine mount

  2. Dental arch model

  3. Base

Selecting material

1. Select an entry from the Material selection list.

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

• The required tool is displayed depending on the selected material.

Selecting trim parameters

1. Specify the Distance of the trim line from the gingival margin [mm] parameter.



Example: Distance of 0.5 mm



Example: Distance of 3 mm

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

   1. Specify the Trim [%] parameter.

      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. You activate the top view by clicking Z .

      

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

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

1. Specify the Leveling factor parameter.

   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. Specify the Leveling factor oral parameter.

   

   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.

4. 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 posterior molars. Specify the parameter.

   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

5. Adjust the parameters described above step by step until you are satisfied with the displayed trim line. Wait for the complete calculation of the dental arch model.

6. If the defined parameters apply to many of your typical jobs, select Save as job template.

7. If necessary, edit the trim line manually using the Trim line editor.

    (Optional) Manually edit trim line

   Important: As soon as you change additional machining parameters of the job, the calculation of the affected dental arch models is updated and previous adjustments to the trim line are reset.
