Automatic 3D modeling for orthodontics

EasyModel creates all types of orthodontic models: working models, study models, models for fixed retention wires and splints, and soon, trimmed models for braces. We strive to continue developing new features to meet our customers’ needs, and more model types will be available in the coming months. Don’t hesitate to contact us if you have any questions about the types of models available on EasyModel.

EasyModel can produce all the main models used in orthodontics, and the list of models will continue to grow.

Once the prosthetist has chosen the model to be produced and defined the parameters, the 3D model is produced from the raw scan fully automatically.

The tasks carried out by EasyModel depend on the type of model to be produced and the parameters supplied when the treatment is launched, but in general they are all the preparatory tasks carried out by the dental technician in his dental CAD software when he receives a scan. In particular, we find the following actions:

• • Artifacts removal such as pieces of cheek, tongue or finger from the scan manipulator.
  • Filling in missing parts of the impression
  • Remove the palate, as required.
  • Cutting out the gum with a height adapted to the desired model.
  • Cuting to retain only the teeth required for the desired model.
  • Straightening the occlusal plane so that it is perfectly horizontal.
  • Filling the support according to the provided parameter (full, hollow, honeycomb).
  • Adding a base plate if requested
  • Alignment of the plane according to the model on the horizontal, vertical, or profile axis (X, Y, or Z) as per the provided parameter.
  • Height adjustment
  • Reconstructing a false palate and lingual floor
  • Engraving the model with the provided text
  • Trimming the contours of certain teeth to attach molar bands

New features will soon be added to EasyModel :

• Remove brackets
• Models for whitening trays
• Drafts, undercuts, and interdental spaces
• Generating attachment points for articulation brackets

You can find the details of these tasks and the processing parameters on the EasyModel task description page.

In addition to the choice of the target model type, the parameters are:

• • Type of cut (study model, working model, splint and fixed retention wire model)
  • Type of support (full, hollow or honeycomb)
  • Model height
  • Model alignment axis for printing: horizontal, vertical or profile (X, Y or Z).
  • Engraving (height, depth and text)

The accuracy of digital models depends on the quality of the scans supplied. We use advanced algorithms to process the scan data and create a digital impression that is not degraded from the original scan.

Before launching a treatment, the tool checks the quality of the scans provided as input. If the scans are incomplete or not accurate enough, an error is generated, no processing is done and your DC$ credit will not be affected.

Once the scan has been downloaded, it takes about a minute to create a model. Note that the treatments are parallelized and therefore the realization of a model or any number of models simultaneously will take the same time. If you have a batch of templates to make, we advise you to download all the scans, to set up the templates to make and then to launch the batch which will be processed in less than a minute.

EasyModel is working on compatibility with the main articulation supports on the market. Register on the site and we’ll let you know when supports become available.

Of course. EasyModel produces files in STL, PLY or OBJ formats. Once you have retrieved the model from your CAD software, you can modify it as if you had made it manually. Don’t forget, if you detect a major problem in a model, you just have to declare it as an error and describe the problem to be re-credited with the corresponding DC$.
