Digital Dentistry

Digital Dentistry

In dentistry, the use of computer technology and modern dentistry came together to bring digital dentistry. Digital dentistry is rapidly advancing towards becoming the key to the future with its modern technology.


CAD CAM (Computer Aidet Design-Computer Aidet Manufacturing)that means Computer Aided Design-Computer Aided Production. Cerec, which combines these two technical concepts, was developed for dentistry, 3D (3D) It is a design and production device working with computer support. 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 area, not the two-dimensional projection image as in tomography and x-ray.


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 from zirconium and porcelain blocks (coating teeth)production of bridges and fixed prosthesis substructures.


1-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.

2-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. CAD CAM system has developed and increased the use of sintered glass, polycrystalline alumina, zirconium and porcelain-based materials and their derivatives, which are not easy to process with conventional methods, but have high aesthetic appearance and biocompatibility. New materials, such as zirconia, that are very difficult to process with traditional methods CAD CAMIt can be prepared successfully and aesthetically with the system.

3-Traditional Measurement Method has been Abandoned.

Cerec CAD CAM system has abolished the traditional measurement, 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.

4-CAD CAM Reduced The Chance of Error.

Advances in digital dentistry have reduced dentist and dental technician-related failures. 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.

5-CAD CAM has increased the success and aesthetics of implant treatments.

a-Implant Placement with Digital Dentistry

Intraoral image is taken with 3 D Cerec camera of the area showing missing tooth in the image obtained by 3D tomography and where implant placement is considered. 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.


Working principle of Cerec Cad Cam System: 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 Phase 1: 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. 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.

Stage 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.

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

Moreover, CERECsystem allows the zirconium infrastructure and the porcelain to be used on it to be milled together, and then these two parts are combined with each other.

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.

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


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 change, and the frequency of the contact points with the opposing teeth, on the teeth transformed into 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.
