In dentistry, the use of computer-aided medical technology has come together with modern dentistry and created digital dentistry practices. Digital dentistry is rapidly advancing towards becoming the key to the future with its modern technology.

Digital Dentistry and Cad/Cam

CAD/CAM (Computer Aidet Design-Computer Aidet Manufacturing) stands for Computer Aided Design-Computer Aided Manufacturing. Cerec is a 3D (3D), computer-assisted design and production developed for dentistry that combines these two technical concepts. is the device.

Cad Cam is one of the most important application areas of digital dentistry. The 3D technique allows to have information about the shape of both the outer and inner surface of the examined region, not the two-dimensional projection image as in tomography and x-ray.

How Cerec Cad Cam System Works

The essence of the system is that the images obtained from the intraoral camera, which takes three-dimensional optical impressions, are processed by means of computer programs suitable for the purpose, and sent to a very sensitive micro milling machine working with computer software; with this method, inlays, onlays, crowns (cover teeth), bridges and fixed prosthesis substructures are produced from zirconium and porcelain blocks.

What are the Advantages of Digital Dentistry?

Treatment Time Has Been Shortened: One Visit Dentistry

With the computer system, applications can be made in a single session in the clinical environment and dental treatments can be completed in two hours. This prevents time loss for both the dentist and the patient.

Increased the Use of Materials with High Aesthetic and Biological Compatibility

The search for biologically reliable materials as well as aesthetics by both patients and modern digital dentistry has increased the demand for metal-free denture treatments. The CAD/CAM system has developed and increased the use of sintered glass, polycrystalline alumina, zirconium and porcelain-based materials and their derivatives in dentistry, which are not easy to process with conventional methods, but have high aesthetic appearance and biological compatibility. New materials such as zirconia, which are very difficult to process with traditional methods, can be successfully and aesthetically prepared with the CAD/CAM system.

Traditional Measurement Method Has Been Abandoned

The Cerec CAD CAM system has eliminated the traditional impression, wax modeling method. Digital/optical measurement is taken. The old method provided an advantage for patients with nausea and/or gag reflex during impression taking. High resolution and laser-assisted intraoral micro digital camera can take impressions with micron level precision. In addition, digital impression taking minimizes the risk of infection during conventional impression taking and fitting.

Cad/Cam Reduces the Chance of Error

Advances in digital dentistry have reduced dentist and dental technician-related causes of failure. However, it did not completely eliminate it. For this reason, tooth cutting techniques and cavity preparation rules should be followed, and bonding and closing controls should be done carefully.

Cad/Cam Increased the Success and Aesthetics of Implant Treatments

a-Implant Placement with Digital Dentistry

3D Cerec camera also takes an intraoral image of the area where the implant is planned to be placed and shows a missing tooth in the image obtained by 3D tomography. Both images are superimposed in the computer environment to obtain the possible restoration and the most ideal implant placement angle and depth with 3D software. Thus, the risk of complications in implant surgery is reduced, and the prosthetic superstructure to be made on the implant is prepared perfectly.

b-Production of Zirconium Abutment

With the Cad/Cam device, implant abutments can be prepared from zirconium with high biocompatibility or reinforced ceramic, thus, personalized aesthetic and functional zirconium abutments can be obtained. When zirconium or ceramic abutments are preferred, abutments that provide maximum harmony with the oral tissues, give an aesthetic appearance due to reflecting the light like a natural tooth, and contribute to oral hygiene due to the lack of bacterial retention are used.

Orthodontic Transparent Plaques Can Be Produced With Cad/Cam Systems


Optical, digital measurement of the prepared cavity or the prepared tooth is taken from the inside of the mouth with a camera. The design is made with a computer program suitable for the purpose, the block is scraped and sintered if necessary. The detailed steps of the process are as follows.

In the 1st stage: measurements are taken with an optical camera. The measurement taken is transferred directly to the computer to which the camera is connected.

Stage 2: After the computer renders the images in three dimensions, the margins and contours are determined by the dentist, and a suitable design is made for the tooth. With its biogeneric feature, the system can offer restorations similar to the existing teeth of the patient.

Stage 2: The dentist can perform operations within the framework of this recommendation, as well as make any changes he wishes. It can control the contact points with the opposing teeth, virtually wear, add, change the contours, increase or decrease the frequency of the contact points with the opposing teeth.

Step 3: After the design is finished, the appropriate color and size block is selected. The tooth form is obtained by milling the block with a micro-turning device.

The blocks used with the CEREC system can be glass ceramics reinforced with feldspathic and leucite, as well as porcelain ceramics with high resistance such as lithium disilicate, nano ceramics.

In addition, the CEREC system mills the porcelain to be used on it together with the zirconium infrastructure, allowing these two parts to be combined with each other later on.

Stage 4: It is the stage of polishing, coloring and glazing of porcelain, zirconium and material, which is given the form of prosthetic tooth or inlay or onlay filling. High-tech furnaces are used for this process.

After the digital measurement is taken with the CAD CAM system used in the clinic, the design and production is carried out next to the patient and the process can be completed in a single session.

Digital Dentistry and Smile Design

Another advantage of digital dentistry is that aesthetic smile design can be done. The Cerec system allows the individual to make the desired changes in accordance with the face and mouth structure, to control the contact points with the opposing tooth, to make virtually abrasion, insertion, contour changes, the frequency of the contact points with the opposing teeth, on the teeth transformed into a three-dimensional form with the help of a micro camera. allows it to be increased or decreased.

In addition, the images of the possible finished teeth obtained with this method are matched with the real face photograph of the individual, and the dentist and the individual have the opportunity to see the new restoration before it is finished. Information about the aesthetic smile design to be acquired will be obtained before the procedures.
