Digital Dentistry
In dentistry, the use of computer technology and modern dentistry have come together to bring digital dentistry. Digital dentistry is rapidly progressing towards becoming the key to the future with its modern technology.
DIGITAL DENTISTRY AND CAD CAM
CAD CAM (Computer Aidet Design -Computer Aidet Manufacturing)that means Computer Aided Design-Computer Aided Manufacturing. Cerec combines these two technical concepts, developed for dentistry, 3D (3D) computer support. It is a design and production device that works with Cad Cam is one of the most important application areas of digital dentistry. The 3D technique allows obtaining information about the shape of both the external and internal surfaces of the examined area, rather than a two-dimensional projective image as in tomography and x-ray.
HOW DOES THE CEREC CAD CAM SYSTEM WORK
strong>The essence of the system is that the images obtained from the intraoral camera that takes three-dimensional optical measurements are processed by 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 (covered teeth), bridges and fixed prosthesis infrastructures are produced from zirconium and porcelain blocks.
WHAT ARE THE ADVANTAGES OF DIGITAL DENTISTRY
1-Treatment Duration is Shortened: One Visit Dentistry
With the computer system, applications can be performed in a single session in the clinic environment and dental treatments can be completed in two hours. This prevents loss of time for both the dentist and the patient.
2-It Increases the Possibility of Using 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 prosthetic dental treatments. 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 prepared successfully and aesthetically with the CAD CAM system.
3-Traditional Measurement Method Has Been Abandoned. >
Cerec CAD CAMsystem has eliminated the traditional measurement and wax modeling method. Digital/optical measurements are taken. The old method was advantageous for patients who had nausea and/or a gag reflex during measurement. A high-resolution and laser-supported intraoral micro digital camera can take measurements with micron-level precision. Additionally, digital impression taking minimizes the risk of infection during traditional impression taking and fitting.
4-CAD CAM Reduced the Possibility of Error.
Developments in digital dentistry It has reduced the causes of failure due to dentists and dental technicians. However, it could not eliminate it completely. For this reason, tooth cutting techniques and cavity preparation rules should be followed and bonding and closing checks should be done carefully.
5-CAD CAM Increased the Success and Aesthetics of Implant Treatments.
a-Implant Placement with Digital Dentistry
Implant placement The intraoral image of the area that is thought to show missing teeth in the image obtained on 3D tomography is also taken with a 3D Cerec camera. By superimposing both images in a computer environment, possible restoration and the most ideal implant placement angle and depth are obtained with 3D software. Thus, the risk of complications in implant surgery is reduced and the prosthetic superstructure to be built on the implant is prepared perfectly.
b-Zirconium Abutment Production
Cad Cam device Implant abutments can be prepared from highly biocompatible zirconium or reinforced ceramics, thus personalized aesthetic and functional zirconium abutments can be obtained. When zirconium or ceramic abutments are preferred, abutments that provide maximum compatibility with intraoral tissues, provide an aesthetic appearance because they reflect light like natural teeth, and contribute to oral hygiene due to low bacterial retention are used.
CEREC CAD. WHAT IS THE DENTAL TREATMENT PROCESS WITH CAM DEVICE?
Working principle of Cerec Cad Cam System:Optical and digital measurements of the prepared cavity or prepared tooth are taken with a camera from inside the mouth. The design is made with a computer program suitable for the purpose, the block is engraved and, if necessary, sintered. The detailed stages of the process are as follows.
1. In this step: Measurements are taken with an optical camera. The measurement taken is transferred directly to the computer to which the camera is connected.
2. Stage:After the computer makes the images three-dimensional, the margins and contours are determined by the dentist and a design suitable for the tooth is made. With its biogeneric feature, the system can recommend restorations similar to the patient's existing teeth. The dentist can take action within the framework of this recommendation. As you know, you can make any changes you want. Checking the contact points with the opposing teeth, making virtual abrasions, additions, contour changes, and increasing or decreasing the frequency of contact points with the opposing teeth.
3. Stage: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 lathe device.
The blocks used with the CEREC system are feldspathic and leucite-reinforced glass ceramics, as well as porcelain ceramics with high resistance such as lithium disilicate, It can also be used in nano ceramics.
In addition, theCERECsystem mills the porcelain to be used on it together with the zirconium substructure, allowing these two parts to be combined with each other later.
< p4. The stage is the polishing, coloring and glazing of the porcelain, zirconium and material, which are given the form of a prosthetic tooth or inlay or onlay filling. High-tech ovens are used for this process.Following the digital measurement with the CAD CAM system used in the clinic, design and production are carried out in the patient's presence and the process can be completed in a single session.
DIGITAL DENTISTRY AND SMILE DESIGN
An advantage of digital dentistry is the possibility of aesthetic smile design. The Cerec system allows the individual to make desired changes in accordance with the face and mouth structure on the teeth, which are transformed into three-dimensional form with the help of a micro camera, to control the contact points with the opposing tooth, to make virtual abrasions, additions, contour changes, to increase the frequency of contact points with the opposing teeth. It allows to increase or decrease.
In addition, with this method, The images of the possible finished state of the desired teeth are aligned with the individual's real face photograph, and the dentist and the individual have the opportunity to see the new restoration before it is finished.
