📖 Workflow

The Medit Model Builder workflow consists of 7 steps, which must be followed in a specific sequence. After assigning the data, the user proceeds to the Overview step to review the imported scan data. Working in the final 3 steps is optional, and the user can proceed to “Complete“ right upon creating the model base.

	Overview	Check the imported scan data.
	Area Designation	Designate the area for base creation.
	Data Editing	Edit and trim data using the wide array of functions provided.
	Data Alignment	Move data to the occlusal plane of a virtual articulator.
	Base Creation	Create the base for the model.
	Die Creation	Create dies that will be used in the base model.
	Attachments	Add support elements or other attachments to the model.
	Labeling	Label the model, either engraving or embossing the text.
	Complete	Finish the model creation process and save the results to Medit Link. ⚠️ Paid Feature Saving and exporting the completed design as an STL file is a paid feature. Pricing may vary based on your scanner ownership status and location. For more details about payment, please visit the Medit Help Center or click here.

Overview is the landing page of Medit Model Builder, where the imported data is shown.

1. Check your scan data for any holes or issues that may require editing. Ensure the data is not trimmed too close to the teeth and includes some gingiva data.

2. Once you're finished, click the "Area Designation" icon at the top to start creating the model.

In the first step, the teeth portion of the scan data is automatically detected, and a section of the data is selected to designate the area that will be used to create the model base. Although this step is automated, it is recommended that the user review the selection to ensure accuracy.

	Remove	Use the mouse to remove parts of the data. Hotkey: 2
	Smooth	Use the mouse to smooth parts of the data. Hotkey: 3
	Morph	Use the mouse to morph parts of the data. Hotkey: 4

Align the data with the virtual occlusal plane to properly place the data on the base.

If the alignment has already been done in Medit Scan for Clinics or Medit Scan for Labs, you can skip this step. However, we recommend checking the alignment to ensure proper positioning of the data on the base.

Toolbox

	Align with Occlusal Plane by Three Points	Select three points on the maxilla or mandible to align with the occlusal plane.
	Align with Occlusal Plane by Four Points	Select four points on the maxilla or mandible to align with the occlusal plane. It is beneficial when there are no anterior teeth.
	Delete Marker Point	Remove the points selected for alignment.
	Detach Data	Separate the aligned data and move it to the original position.
	Multi-View	When on, this function shows data from four different angles.

1. As shown in the image below, select three or four points on the data. Then it will
be automatically aligned to the occlusal plane.

2. Adjust the data around in the Multi-View on the right to adjust its position on the occlusal plane.

3. Turn off the Multi-View to only show the occlusal plane part on the screen.

4. Click “Next” when finished.

The Base Creation step is the key to model creation. You can select the base type and adjust it across various parameters such as base height, wall thickness, number of drain holes, and more.

Toolbox

	Base Type	Select one of the available base types: ABO, Plate or Plateless Model.
	Total Height (mm)	Use this slider to adjust the total height of the model, including the base and scan data. ℹ️ Note The total height of the model can be up to 99mm. It might be useful to check the maximum height of the model available to print with your 3D printer to set a height limitation.
	Hollow Shape	Hollow out the base and adjust the wall thickness. ℹ️ Note Hollowing out the shape is useful when printing the model using less material. Each type of base can be hollowed out.
	Wall Thickness (mm)	Use this slider to adjust the thickness of the walls once you choose to hollow out the model. ℹ️ Note The range of wall thickness is 2 - 4 mm. It might be useful to check your 3D printer recommended settings to make a correct decision on the wall thickness.
	Straight / Curved (Straight)	Make the base at the edge of the scan data straight. ℹ️ Note Only available for the Plateless Models.
	Straight / Curved (Curved)	Make the base at the edge of the scan data curved. ℹ️ Note Only available for the Plateless Models.
	Create Drain Holes	Create drain holes to drain out uncured resin and set their quantity, diameter and distance from the base. You can click on the circle to freely move and place the drain hole wherever you like. ℹ️ Note Using drain holes is useful for resin printing since they help remove the excess resin and ensure that no material gets stuck inside the model.    ℹ️ Note Only available for the Plateless Models.
	Infill	Create a honeycomb structure inside the hollow base.
	Bevel	Turn on to create a bevel.
	Preview	Preview the model before moving to the next step.

Straight	Curved

1. First, select a base type among the three available options: ABO, plate, and plateless.

	ABO	Create an ABO model. This orthodontic option creates a maxillary base with seven angles, while the mandibular base takes an elliptical form.
	Plate	Create a plate model. The plate will follow the shape of the scan data.
	Plateless	Create a plateless model. Usually made in a horseshoe shape, the base will recreate the shape of scan data.

• You can adjust the height of the base using the up/down arrows located by the scan data. Or use the slider at the bottom to get precise measurements.
  
  

2. If you want the base to be empty inside as shown on the image below, turn on
“Hollow Shape.”

• The hollowed-out base can be further customized by adjusting the wall
  thickness.
  
  

3. Create drain holes for hollow models by clicking the “Create Drain Holes” icon at
the bottom and turning on the toggle. Check parameter options available for drain
holes and adjust them as needed.

• You can move the drain holes freely from left to right by clicking on the circle and dragging it horizontally.
  
  

4. Turning on the “Infill” feature will create a honeycomb inside the hollowed-out
base. This is a helpful feature for 3D printing as it will improve the strength of the
printed model.

5. Click on "Bevel" to turn the toggle on and off. Turning the "Bevel" option on is
helpful for 3D printing because it makes it easier to separate the printed model
from the build plate.

6. Before moving to the next mode, click “Preview” to visualize and examine all adjustments you have made in this mode.

7. Click "Next" when finished. 

In Die Creation, you can create individual dies that are detachable from the base model. Customize your dies easily using the numerous options provided, such as die gap, pin height, extra gap from margin, etc.
