DENTAL MASTER MODELS FOR RESTORATION
Prosthetics and implants
While the majority of dental models are still produced manually from plaster casting, dentists are increasingly using intra-oral scanners, thereby bringing the workflow into the digital realm, which is expected to result in a sharp increase in the demand for dental models over the coming years.
To meet the increasing demand, dental laboratories need to increase their production capacity while maintaining the necessary precision and quality of their master models.
Contact us for more information!
Thanks to 3D printers, dental laboratories can increase their production capacity and decrease per-unit cost while reducing manual work and improving material efficiency.
Additionally, while traditional stone models are unprecise, 3D printed master models are now allowing unrivaled surface finish and accuracy in all 3 dimensions for bridges and crown work, not depending on technician expertise.
Return over the investment
Generally speaking, and this is valid for all the applications, the ROI of moving to digital dentistry can be summarized in
- Better precision and quality
- Faster production cycle
- Great results consistency, unbounded to the personal skills of the operator
- Better efficiency, in terms of costs and time
- Increased patient’s comfort through all the steps of the process
Productivity and costs: master models for prosthetics and implants
Production throughput and costs forecasts are important indexes to be evaluated when it comes to choose the right machine.

| Total time @50μm LT (hours) | 4h 45min |
| Total time @100μm LT (hours) | 2h 25min |
| Time per part (@50µm) | 6min 20sec |
| Time per part (@100µm) | 3min 15sec |
| Average cost per model | 2.45 € |
Prodways’ exclusive Dismountable metal platform
The Prodways dental 3D printers feature granite build platforms (perforated platform as option) for increased Z accuracy and reduced post processing time (no support needed), improving productivity and part quality at the same time.
Dental master models: printing workflows
The standard workflows to get to a master model with the digital dentistry approach are two:
Workflow A (Direct)
| Dentist | Lab | Dentist | ||
|
1
Get the scan of the patient mouth using an Intraoral 3D scanner like 3Shape Trios scanner *
|
2
Use dedicated CAD software having the scanned dental models as a base, to design prosthetics and implants **
|
3
Digitally place the 3D models on the build platform of the machine
Manual, semi-automated or automated nesting tools are available (***) |
4
On the machine, choose the material, load the geometries in STL format and print the models.
|
5
Now the dentist/ technician can work on the printed model to develop the prosthetics and implants for the customer
|
Workflow B (Indirect)
| Dentist | Lab | Dentist | |||
|
1
Get the dental impression with the standard methods (alginate mold).
|
2
3D Scan the alginate mold with a lab scanner like the 3Shape D2000*
|
3
Loading the 3D mold scan in a dedicated CAD software to create the “positive” model, and to design prosthetics and implants. **
|
4
Digitally place the 3D models on the build platform of the machine
Manual, semi-automated or automated nesting tools are available (***) |
5
On the machine, choose the material, load the geometries in STL format and print the models.
|
6
Now the dentist/ technician can work on the printed model to develop the prosthetics and implants for the customer
|
3rd party software integration
To provide to its customers fully integrated solutions, from the dental scan to the part design, to the layout optimization to the printed part, Prodways collaborates with 3Shape, 3D scanners manufacturer (*) and CAD/CAM software developer (**/***), along with Materialise and Autodesk (***).
Prodways ProMaker LD and workspaces are available on all the most advanced software for dental application on the market.

Prodways machines and materials for dental prosthetics and implants
Promaker LD Thanks to the unique combination of high accuracy and productivity of our MOVINGLight® printers,
and to the 3D printing resins specially developed for the dental market,
our customers are able to print prosthetic models for crowns and bridges
with the highest speed/quality ratio in the field.
ProMaker MOVINGLight® printers, unlike other DLP®/Stereolitography printers, use no consumables, making it possible to provide industrial-grade productivity while keeping ownership costs low.
