Scheme of the automated organization of work, allowing you to produce super-precise and super-strong dentures quickly according to CAD/CAM technology:

Step 1 – Cast. Plaster model obtaining an impression of the oral cavity is performed in the same way as with traditional methods of dental prosthetics. A plaster model of the patient’s jaw is made from the obtained impression.

Step 2 – Scanning. The main goal of this step is to obtain digital data on the basis of which electronic three-dimensional models of the required products will be built (crowns, prostheses, bridges, etc.). Digitized data is stored in STL format.

Step 3 – CAD. Three-dimensional modeling (3D).

Step 4 – CAM. Programming processing.

Step 5 – Processing the prosthesis on a CNC machine.

Step 6 – Sintering. Heat treatment of the obtained products.

Open CAD/CAM systems – new technologies – new opportunities in dentistry

The traditional technology of manufacturing dentures (crowns, bridges) is based on casting technology. The prosthesis is based on cast metal, which can be covered with ceramics. Recently, prostheses made of oxide (ZrO2) and zirconium dioxide have become increasingly common throughout the world. In practice, this is a kind of pottery. The advantage of zirconium prostheses is their aesthetic appearance and strength.

Without a metal frame, the prosthesis has a more natural look and color.

The absolute inertness of zirconium oxide determines the confident absence of allergic reactions that may occur in the manufacture of metal prostheses. But zirconium oxide cannot be obtained by casting. In its raw form, the zirconium oxide bar is an easy-to-process material resembling chalk. After sintering in a furnace at a temperature of about 1350 degrees C, the material acquires high strength and hardness characteristic of ceramics. During sintering, the material shrinks, due to which the initial dimensions of the crown are reduced, i.e. Traditional methods for the manual manufacture of zirconium prostheses are not suitable. The manufacture of such prostheses became possible with the introduction of CAD/CAM computer technologies.

Advantages of CAD /CAM dental laboratory automation:

  • Using modern cad/cam technology, you significantly reduce the time of manufacture of crowns. The modeling of the prosthesis in the CAD system takes only a few minutes. Automatic creation of the processing trajectory in the CAM system also saves the time of work of dental technicians
  • The fitting and completion of crowns with the use of cad/cam technology are reduced as much as possible, including by first taking into account the shrinkage of the material during sintering (we get a ready-made crown that exactly matches the scanned print).
  • Optimization of working time of specialists – reduction of their routine work, release of working time for solving other tasks.
  • Refusal to use third parties for the manufacture of crowns.
  • Processing crowns not only from zirconium oxide (ZrO2), but also from other materials (aluminum oxide, titanium). Choosing a CNC machine determines the list of materials that will be available to you for the manufacture of prostheses using cad/cam technology. The processing of zirconium oxide support all specialized machines for dentistry. If you need to process other materials, we will select the most suitable machine for you.
