CAD CAM systems in dentistry

Often, many industries use one and the same principle in the process of developing something: the creation of a certain model and its implementation into a finished product. Such a solution is called “CAD CAM technology”. It is an abbreviation of Computer-Aided Design and Computer-Aided Manufacture.

Earlier, this approach was mostly applied in the manufacturing industry, but now it is used in many other industries as well, including dentistry.

CAD technologies: features of each type

CAD is a process of creating a specific object using computer systems. Previously for creating drawings, developers used paper, pencils, ruler and a lot of time, but now all the drawings can be done on the computer, saving valuable time.

The peculiarity of this system is that any model is created in 3D format: it can be viewed from any angle and from either side. Moreover, if a specialist does not like something, he can quickly replace any part with a new one. When all components of the model are ready, the project will be given for manufacturing.

CAM is a process of manufacturing models that have been generated by the CAD technology. This process also applies computer systems. But in this case they are necessary for setting up the work of mechanisms in the production process. The operator’s task is to adjust the machine so that eventually all materials for the future object have the necessary shape, and the manufacturing process has passed according to certain instructions.

CAD and CAM form a complete integrated system. With the help of the first technology, person creates an object model, and the second one is used for managing the manufacturing process.

CAD CAM systems in dentistry: classification of functions

Using these two technologies, it is possible to design and create a wide variety of objects. For example:

  • to design inlays, onlays, veneers, tooth crown, dental bridges;
  • to customize automated modeling of teeth thanks to the anatomical gallery;
  • to design up to 16 teeth per session;
  • to save all models in the system for further use;
  • to create models in five steps from the very beginning to milling process.

Examples of CAD CAM systems application in dentistry

If we talk about specific application examples of such systems, it should be mentioned that the most common process is modeling and creation of dental fillings. Since there is a limited number of materials used in the filling, it is not always possible to achieve a qualitative and long-acting result.

CAD CAM technologies provide a wide range of materials for stopping. For example, they can be used for making quality ceramic fillings. They have a number of advantages comparing to the traditional options:

  • base can be mixed so that the filling color doesn’t differ from the tooth color;
  • ceramic fillings have higher wear resistance;
  • this material has a high level of biocompatibility;
  • such fillings can be used to strengthen damaged teeth.
