What kind of jobs can DentalCad perform?

DentalCad is one of the most complete solution for the virtual dental design in the current market. With this software, you can recreate with great speed and range single or multiple anatomical crowns, single or multiple small caps, single or multiple simple copings, inlays/onlays, veneers (veneers), works on plants, attacks, bars, telescopics, jobs on double arch and much more.

Can I export my works and in what format?

DentalCad is a fully open tool where you can export and import all kind of modeling because the scanner works in the STL open format, usable by all CAM programming software for the subsequent production by milling or prototyping machines.

How does DentalCad manage my work?

DentalCad has a simplified clear interface for the easy use of all types of user. Through the order manager, it has the ability to store your works, in a clean and clear way, dividing my work for medical and feature processing, with the ability to save a large number of projects in its database without the use of external hard disk.

Can I update my anatomic or implant libraries?

Yes. In an extremely easy way, you can modify or implement and save anatomical and implant libraries according to your needs through a free, clear and fast consultation with our development team.

What does “step by step” mean?

It is our philosophy because we have created DentalCad modeling software step by step. It is always step by step that we keep developing and improving it to keep up with the times and the needs of users. This is the reason why the software is clear and easy to use and accompany the user during every stage of the process via a “step by step” path, the strength of our methodology.

How can I learn to use DentalCad?

We arrange Webinar Tutorials to help you learn about how to use the software. A webinar is a seminar or presentation that takes place on the Internet, allowing participants in different locations to follow lectures with the possibility to interact with the administrator asking questions or answering polls.

What are “cloud points” and .STL files?

The points cloud is the resulting product from the scan. It is a set of millions of points arranged and measured in a 3D environment. The scanner is able to capture millions of points in few seconds. The final scan can be viewed using special software that joins the points by forming millions of triangles connected: the .STL file.

You can not keep the texture if you make substantial changes on the mesh (i.e. extrusions, closed holes, etc.)

How can I select the model?

Check in the “select mode” (by default in on the left above the menu “management model”) if the correct selector [point cloud – mesh – surfaces] is turned on.

How can I zoom in/out the model?

To zoom in/out the model you need to use the mouse scroll wheel.

How can I shift the model?

To shift the model you need to:

Hold down the CTRL on your keyboard
