Below are the main steps involved in generating high-quality 3D dental models
Orthodontic models in AI: joint soft-tissue removal
EasyModel automatically removes any unwanted artefacts, including soft tissues such as cheeks and tongue, to produce a clean and accurate dental model.

Types of cuttings for customized orthodontic models
Model
This type of cut preserves as much of the gingival details as possible and varies depending on the arch. For the maxilla, the palate is preserved to adapt to various types of appliances (plates, pendulum, palatal arch, quad helix, etc.). For the mandible, the cut is made close to the gum junction to help the technician assess the vertical space available for certain appliances.
Splint models
Optimized for thermoforming, this cut preserves only the teeth and a narrow margin of gingiva.
Fixed retainers
Similar to splint cuts, this method minimizes the gingiva and hard palate. The cut is made in the after the X5 teeth on the anteroposterior axis. The cut is made in the middle of the X5 teeth on the anteroposterior axis.
Base creation for 3D orthodontic models
You can choose from four base filling options:
- Hollow
- Hollow with palate plate
- Gingiva-only filling (solid)
- Full solid base (with plate)
Hollow
Holow with Plate
Full
Full with Plate
Engraving orthodontic models with AI
To engrave your model, simply enter the desired text. It will be automatically engraved on the base or the largest flat surface detected.

Other treatments available
We also offer other options such as:
- The filling of the model with a reinforced honeycomb structure, specifying the diameter and thickness of the cells.
- 3-axis rotation for optimized print layout
- Study model (American standard).

Model making – Cleaning/Cutting
How does the creation of a model proceed?
The main steps in making an orthodontic model are generally
- Cleaning the rough scan
- Cutting
- Base creation
- Additional treatments
What is rough scan cleaning?
This is a common treatment for all models. The aim is to remove artefacts that correspond to capture aberrations or external elements such as the manipulator’s finger. Next, the soft tissues (buccal mucosa, tongue, floor of mouth, uvula, tonsils and soft palate) that are of no interest for orthodontic prostheses are removed. EasyModel’s AI has learnt to recognise these elements and removes them in a first processing stage.
What kind of cutting do you do after cleaning?
Cutting depends on the use of the digital model:
- The simplest approach is limited to cutting out the upper or lower part of the maxilla or mandible from the scan after cleaning. This model type is used for the appliances generation such as plates, pendulum, quad helix, etc. This type of model is used for the manufacture of prostheses such as plates, pendulum, quadhelix, etc.
- The “splint” cut corresponds to the manufacture of splints only, and therefore conforms to the constraints of thermoforming for this type of prosthesis.
- The “fixed retainer” type of cutting corresponds to the manufacture of fixed restraints only and is therefore adapted to the needs of this manufacture.
In the case of simple models, what are the differences in cutting between the maxilla and the mandible?
For the maxilla, the cut leaves the entire palate and sufficient gingival height to be used for all types of appliance. For the mandible, the cut must be made at palate level, as close as possible to the gum line, to enable the prosthetist to judge the height available in the mouth to adapt certain appliances.
How is the cutting done for the splint models?
Here, for both maxillary and mandibular teeth, we preserve only the teeth and a margin of a few millimeters of gums (and potentially palate if present) around the teeth. In addition to the elements commonly removed, we therefore remove (if present) the superfluous parts of the palate and gums.rnrnThe normal cut passes as close as possible to the teeth. The normal cut passes as close as possible to the teeth. On request, the “long splint” cut-out leaves an additional 3 mm of gingival height.
How is the cutting done for the fixed retainer models?
Here, in addition to the common removals, the hard palate and posterior teeth are also removed. Only the anterior part up to the middle of the second premolar is kept. Only the anterior part up to the middle of the second premolar is kept.
Are you planning any other orthodontic models?
The next models available will be trimmed models for molar bands and specific models for mobile device support.
Tasks performed on the models after cutting
What tasks are performed after cutting?
Depending on the model configuration and selected parameters, the following tasks can be applied:
- Occlusal plane adjustment
- Base creation at different heights.
- Model engraving.
- Study model format
- Model alignment on the printer build plate.
What types of bases are possible?
Depending on the user’s choice, EasyModel can leave the models hollow or full them with a honeycomb structure or a smooth surface. The palate can be left empty or filled with a smooth surface.
How is the model engraved?
EasyModel starts by trying to find the wording to be engraved from the file name. The user can enter the text he wants engraved on his model. EasyModel then determines the best surface, i.e. on the plate if there is one on the model, or otherwise on the largest flat surface on which to engrave the specified text.rnrnIt is possible to specify the engraving depth and character height size desired, which will be respected by EasyModel as far as possible.
How do you align the models on the printing plates?
EasyModel is not a 3D printing software. However, to limit redundant tasks to the user, he can arrange the models according to the axis he indicates to optimize the layout on the plate during printing.
Dental models
What types of dental models do you offer?
For dental, you can generate simple models (see above). This avoids tasks as artifacts removal, soft tissues cleaning, occlusal plane adjustment or engraving. We’re currently developing additional features specifically for dental applications.
