Our teeth make up an important part of our face when talking and laughing. We need to pay attention to our dental health in terms of aesthetics and health. Disruption of dental treatments, throwing them into the background can cause irreversible results. In this article, we will talk about zirconium, which has been popular in recent years, especially for patients who are not satisfied with the appearance of their teeth.
Zirconium is a white, light-transmissive metal. It has a very high resistance to pressure. It is biologically tissue friendly. Studies have proven that it does not cause any allergies. In the treatment of dental diseases, the skill of the physician is more important than the material. Regardless of the material, the treatment cannot be successful without the successful application of the physician.
Zirconium, which has come to the fore in recent years with its aesthetic properties; It is also the ideal dental coating material for patients with metal allergies. It is a new generation dental veneer developed to eliminate the deficiencies of zirconium dental veneer porcelains in dentistry. Zirconium, which can be applied to any color tooth, can be the desired color regardless of the actual tooth color of the patient. Due to the light transmittance, which is the most important factor in aesthetic dental veneers, the desired appearance is achieved on the front teeth while smiling.
How is Zirconium Coating Applied?
In the zirconium coating process, the patient’s teeth are reduced. This is also called tooth cutting. In this process, the patient’s teeth become more sensitive to hot and cold. In order to pass this period, the patient may sometimes be fitted with a temporary prosthetic tooth. Installing the denture will protect the patient from discomfort due to aesthetics and sensitivities.
The preparation of zirconium teeth is the same as with classical metal-supported porcelain, but the difference begins in laboratory procedures. Zirconiums can be made with devices with computer technology. In this method, the measurements taken from the patient’s mouth are scanned on optical readers in the computer environment. It is cut and shaped by computer from zirconium sheets by means of milling systems without human touch.
The data obtained with the help of the camera is uploaded to the computer. Then designs (CAD) are made and production (CAM) is started.
With these developed technologies, zirconium is successfully used in single-tooth crown restorations, 3-6 member bridges, and crown-bridge works on implants.
While the zirconium dental crown is being made, the three-dimensional structure of the teeth is transferred to the computers with scanners after the teeth are cut. This scanning process is of two types. In the first process, as soon as the teeth are cut, the image is transferred to the digital environment with the help of intraoral scanners and camera, without placing any impression material in the patient’s mouth, and after this process, the planning is completely prepared in the computer environment. Then data is sent to the cad cam system. Here, zirconia blocks are turned into the infrastructure of porcelain teeth with the help of rotary systems. In the other method, measurements are taken from the mouth after the patient’s teeth are cut. After the measurement is taken, the measurements that go to the laboratory are poured with special plaster systems and the original measurement is obtained. Then, these measurements are scanned with special tools similar to scanners in computers and transferred to the digital media, that is, to the computer.
The substructures are rehearsed and sent to the laboratory for the processing of the superstructure, namely the porcelain. The zirconium porcelain tooth is now ready.
