RAW is a 100% pure digital workflow that has its roots in the SKYN concept. It is designed to copy the unaltered geometry of nature.
It integrates a simplified 3D version of smile design, that works as wireframe for importing natural shapes. Yes, you can create your own database.
It is designed to be precise and have an easy integration with surgery / implant dentistry.
RAW defines a clear synergy between 3D print and CAD/CAM in the clinical workflow.
Below you can see the highlights of this workflow.
From our point of view, evolution is heading towards simplicity. As an alternative to DSD, we are using one simple 3D template, that makes it effortless to plan. You no longer need to design, all you need is to define the restorative space, in a tri-dimensional way and import natural design inside it.
In this case we used natural morphology from our own 3DNA™ database, but you can use literally any database, or any shape and texture.
We expect a version of this workflow to be available soon in 3Shape Practice Lab.
The design will serve as a reduction guide for both hard and soft tissue. Soft tissue will be reduced first, followed by flapless bone reduction to ensure biologic width. After tissue is recontoured, we can pack cords and prepare through the mock-up.
This means we can deal with both surgery and preparation in the same day.
The mock-up from the printed model serves as a surgical guide.
Margins from the mock-up when using the
printed model are very precise.
Bone reduction is performed flapless with the CVDentus system
That allows us to take impression the same day and
bypass the traditional healing time from CLP.
This procedure will ensure the biologic width and sulcus depth if needed.
Because of the reduced trauma, healing and tissue quality are incredible.
This allows same day prosthetic procedures.
Design also serves as the preparation guide.
Design will guide both procedures, yet the design itself remains unaltered, unless we choose to make modifications.
We will digitally erase the original scan, and rescan the areas we modified ( surgery and prep ).
This method eliminates all potential alignment errors.
The prep model is printed to an alveolar model, as well as a control model, both from pure scan data. PMMA restorations are milled for provisionalization and test drive ( if necessary ) for the case. At this stage by milling instead of using bis-acryl, we can spot and eliminate all errors such as undercuts, minimal thickness and insertion problems.

There is a wide selection of materials and colors
with various properties and indications based on the case.
PMMA milled provisionals. Inexpensive, Fast and a true testdrive for the final ceramics.
Milled PMMA restorations on 3D printed alveolar model.
Try-in of provisionals. Restorations can be sandblasted and spot etched and are suitable for
short duration as well as long duration provisionalization.
Ceramics are milled from Empress Cad Multi blocks and fitted on the 3D Printed Alveolar model. Contact points are adjusted if necessary. No modifications are made in the shape and texture as we try to preserve the natural design. Polish, stain and glaze.
First of all, there is no distorsion from the traditional impression. The resolution of the print is 100, 50 or 25 microns. For Mock-up models we use 100 microns. For work and control model we use 25 microns. Ever since we started working with 3D Print, several updates reduced printing time with almost 40% and new materials are coming to the market every month and the trend will continue, most likely accelerate. Pictured below is the fit we achieved on a 0.2 mm chamfer. Milled restoration on 3D printed die.
Pictured below you can see that on the left side the PMMA and ceramic in the same try-in, and on the right side, the bonded ceramic. As you can see, the shape and morphology are identical and are not man-made. They are created by the best waxer in the world, nature. We simply found a way to copy it.
