Full Porcelain Crowns Without Metal Support
Porcelain is the closest and healthiest material to tooth enamel. Until a few years ago, porcelains had to be used on a metal infrastructure rather than alone in the mouth. Since the metal infrastructure prevents light from passing through the tooth, it can lead to dull and artificial restorations that are far from the transparency of natural tooth enamel, and gray areas at the gum edge.
Although many things affect the appearance of crowns, the most important is their response to light. . Natural teeth transmit light. As a result, depth and vitality appear in the tooth.
Due to the light transmission properties of porcelain crowns without metal support, their depth and vitality are greater, thus the results closest to the natural tooth are obtained.
What are their advantages?
While full porcelains create an aesthetic very similar to the natural tooth structure because they transmit light, there is a dullness and artificiality in metal-porcelains, even if they are very well made. For this reason, full porcelains are preferred, especially in the front teeth.
Metal-supported porcelains give the appearance of a dark space in the mouth as if it does not exist in some lights (disco, camera flash, etc.). Full porcelains, on the other hand, transmit all kinds of light like natural teeth.
Metal-supported porcelains are mechanically bonded to the teeth. Full porcelains are attached to the teeth mechanically and chemically. Therefore, their retention is much higher than those with metal support. Since there is no metal in the infrastructure of those without metal support, there is no dark line at the crown-gum line. A more aesthetic appearance is provided.
When the gums recede, full porcelains maintain their aesthetic appearance, while metal porcelains create a bad appearance in the area where they meet the teeth.
The risk of allergy to some metals (nickel, etc.) used in the infrastructure is in full porcelains.
What is Zirconium?
For many years, a metal substructure has been used under the porcelain tooth for durability in porcelain applications. Since the disadvantages of this metal infrastructure in terms of gums, dental tissue, general body health and most importantly aesthetics are known. The search for an alternative material to metal in the porcelain infrastructure has been going on for years.
A new era has begun with the application of zirconium, which was previously used successfully in other areas of medicine, in dentistry instead of porcelain metal.
Because this new zirconium In addition to not causing gum problems or allergies, porcelain veneers with substructure allow us to achieve aesthetics and functions close to natural teeth with their light-transmitting properties.
Crowns and bridges made by placing porcelain on zirconium are the combination of the words Ceramic and Zirconium. It is known by the short name CERCON. The system, which has a resistance of 900 Mpa, has started a brand new era in dentistry, with its light transmittance, tissue compatibility and many different indications, in addition to the highest physical values. The success of the material has been proven in medicine and industry. As a result of the research that started in 1998, clinical applications have been implemented all over the world since the beginning of 2002. With this new application, the patient's aesthetic concerns regarding metal-ceramic and full-ceramic restorations are completely eliminated.
Where can it be used?
Single-tooth crown restorations< br /> Bridges with 3-6 members (anatomical length up to 38mm)
Implant crown - bridge studies
What are the Treatment Steps?
Crown or The teeth to be bridged are prepared and their measurements are taken. In the same session, temporary crowns or bridges are prepared and placed on the teeth.
A metal substructure or reinforced porcelain substructure compatible with the prepared tooth surface is prepared in the laboratory. It is checked with the teeth by rehearsing it in the mouth.
After the color of the other teeth in the mouth is determined, porcelain work is done on the infrastructure in the laboratory.
The porcelain-processed crown or bridge is placed in the mouth by the physician, patient and technician to determine whether it is functional and functional. It is evaluated from an aesthetic perspective.
When the desired result is achieved in terms of health and aesthetics, crowns or bridges are permanently placed in the mouth with special materials.
As a result; High Technology for Excellent Results
To date, zirconium oxide has been subject to high costs in production. It was not used in dental applications due to its strength. Thanks to a project developed by the Zurich Federal Institute of Technology, zirconium oxide has become economically usable in dentistry. Zirconium has been used in medicine since the 1960s, and the reliability of the material has been proven by long-term studies. It has been determined that it does not cause allergies.
Zirconium is an element that is resistant to high temperatures, impacts, lightweight, does not conduct heat and electricity, and can transmit light.
It is also a healthy element that does not cause bad taste in the mouth, gum problems and bad breath. It is a material.
A wax model of your teeth is prepared on the model prepared with the impression taken from your teeth. A computer-aided device prepares the infrastructure of your teeth by eroding the zirconium oxide block in line with the information it receives from this model. The work is completed by placing ceramics in the appropriate color on the structures prepared by etching. Metal-free, strong and aesthetic restorations can now be successfully made with the new high-tech product zirconium oxide.
What is Cercon?
Aesthetics, which are the basic requirements of modern dentistry. It is a product with the highest quality ever achieved in terms of durability, texture compatibility and naturalness. Cercon applications also have some important advantages for users. Cercon ceramic placed on the zirconium oxide infrastructure reduces the adhesion of food residues and microorganisms to the tooth surface. Thus, good oral hygiene is ensured. Zirconium oxide does not conduct heat, and your teeth do not become sensitive when you consume hot or cold foods.
MOST ASKED QUESTIONS
Special Is any bonding required?
No, it can be bonded using traditional methods
Can temporary bonding be done?
Yes
Will hot-cold sensitivity develop?
/> No, hot-cold sensitivity does not develop. Because Zirconium Oxide is a heat insulator
Does it cause allergies?
No, Zirconium Oxide is a tissue-compatible substance and does not cause allergies.
Is it opaque?
No
Will the gums recede?
No. Research has shown that it is perfectly compatible with gums. Of course, it cannot stop the gum recession that naturally develops with age.
