The most common, convenient and at the same time inexpensive way to digitize the patient’s teeth and jaw shape is to take impressions, then scan them and create a 3D model.
Using conventional optical scanners for immediate scanning of jaw impressions is not at all easy because of a huge number of concave surfaces producing irreparable shadows. Typically, a gypsum cast is first created from an impression, which is then scanned. This traditional approach leads to the accumulation of errors at each step, reducing the accuracy of the simulation, and also makes the process both longer and more expensive..
A much more efficient solution is direct scanning of prints with penetrating x-ray radiation and restoration of the exact shape of all surfaces using computed tomography (CT). In addition, you can always separate the various areas of the scanned object based on an analysis of the density of the material, and the restoration of not only external but also internal surfaces hidden from view.
We are pioneers and leaders in the implementation of X-ray scanning and computed tomography in restoration applications for dental laboratories.
Unlike conventional devices for CT scanning of the human body, we provide super high-resolution and detailed images of the resulting computer model – which take only seconds to be generated.
As the field’s trailblazers, we had to solve a number of new problems of processing three-dimensional data to ensure a fully automatic scanning process for heterogeneous (consisting of different materials) objects.
In particular, we solved the problems of automatic calibration, reconstruction of the “inner” surface according to the density difference, classification of surface areas belonging to different types of objects, their segmentation, and many other high-tech tasks.
It should also be noted that the model reconstruction program implemented as a cloud service.
