Computers are an important part of new generation production technologies. CAD CAM techniques used for error-free production have an important place in dental treatments. The most applied process is the production of coating or tooth bridge production from zirconium blocks. Zirconium is defined as the daily life of the application is actually referred to the zirconium in the structure of the ceramic is provided with the aesthetics of the tooth coating and bridge.
With CAD CAM systems, whether metal or zirconium blocks, it is possible to obtain the desired shape. The preferred zirconium infrastructure in making aesthetic teeth results in a higher cost price compared to metal. Material has significant advantages from other dental coating materials. If we should briefly summarize;
- Biological compliance
- Less bacterial clinging
- Low thermal conductivity
- No gum withdrawal
- Light reflectivity close to the tooth
countable. The coating material which is produced by scrapping zirconium blocks sold at high prices is subjected to sintering process in the high heat furnace after scraping. The purpose of sintering is to harden the material. In this way, as much as metal-resistant zirconium infrastructure can be obtained.
During sintering, it is known that the material changes and shrinks in size. After the sintering process in high quality zirconium blocks, the bending of the material was calculated. These processes, which require very precise technical infrastructure, can only produce good results with good quality zircon blocks. There is a risk of cracking when zirconium blocks are scraped and hardened in the heat furnace. Such undesirable conditions can be seen as a fracture in the coatings after the tooth coating is attached to the mouth.
ZIRCONIUM WITH PORCELAIN TEETH DIFFERENCE
High technology is used in aesthetic tooth coating applications. However, the desired successful results can be obtained. There is a laboratory infrastructure required for the use of zirconium material. The dental technician begins to work after the dentist receives the oral tooth paste. The model of the teeth in the patient’s mouth is transferred to a model. After this stage, the usual porcelain tooth coating and the new generation zirconium tooth coating procedures differ.
For the porcelain tooth coating, a thin sub-structure is prepared by dropping the wax onto the model. The drug is applied as much as the share of cement on a thin layer. After waiting for the freezing is done modeling on the candle. Wax is taken into the muffle model. The wax in the heat is heated by heating. The prepared model created an empty space in the project.
The centrifugal is poured into this cavity. The casting process without air bubbles is a successful casting. However, during the melting and cooling of the metal, oxidation and dimensional changes occur. The casted metal, which is removed from the revetment, also has rough edges called burrs. A dental technician is able to adapt these cast metal onto the model by abrading them. It is a fact that some undesirable voids are formed between the model and the tooth as the abrasion is carried out. These cavities, which are formed outside the cement share, are cavities that may cause tooth decay under the tooth coating.
This process is different in zirconium coating. Completely computer-aided manufacturing means the harmony of the coating with the error-free teeth. In this way, the coating will not be the case of the future tooth decay.
ZIRCONIUM TEETH PRICES
Except for the investment costs of the laboratory and the cost of use of the CAD CAM system, high wages are paid for each zirconium chip. Every stage is costly, from device software upgrades to changing blocks. The device itself already requires high investment. Competition is scarce because advanced technology is not common. The prices for zirconium coating are therefore higher compared to porcelain tooth prices .
The cost of a zirconium dental coating is more than three times the cost of porcelain tooth coating. These high prices are also reflected in end-user patients. Prices of zirconium teeth are less than the prices of lamina tooth finishes in dental coating prices, but more than porcelain tooth prices
