They are very thin leaflets made of porcelain or composite material and glued to the front surfaces of the teeth with special materials.
What are laminate veneers?
They are very thin leaflets made of porcelain or composite material and cemented to the front surfaces of the teeth with special materials. In order for veneers to be applied, the teeth must be structurally healthy.
In what cases is it applied?
Veneers are used to correct cosmetic defects and closing disorders in the teeth. The appearance of teeth with cosmetic deficiencies, such as slightly curved, coloured, decollated teeth and crooked teeth, can be corrected with veneers. In the past, the correction of these deficiencies could be eliminated by preparing all the surfaces of the teeth and making crown-shaped veneers. When mixed with crowns, much less shaping is required before the veneers are applied. For this reason, anaesthesia is not required or veneers are applied in very small proportions. They are made of porcelain or composite material. Porcelain veneers are more resistant than composite veneers. They are more resistant to tea, coffee or cigarette stains than composite veneers. However, when composite veneer is applied to the tooth, there is no or very little loss of substance from the tooth. The reason for this is that composite veneers can be made much thinner than porcelain veneers. Your dentist will make his decision according to your circumstances. Three appointments are usually required for veneer construction.
Preparation (preparation)
At your first appointment, your dentist checks whether your teeth are suitable for veneer construction. It will then inform you about what the transaction covers and what the limitations are.
In what cases is it applied?
At your second appointment, about 1.5 millimetres are removed from the enamel to provide space for veneers. In some cases, this preparation is not needed. This procedure is not painful, but it can be uncomfortable for some people. Therefore, local anaesthesia can be applied when necessary. The measure of your prepared teeth is taken and sent to the dental laboratory. Your temporary veneers are made in the same session. The shaping of veneers in accordance with your teeth is carried out in the dental laboratory. Veneers need five or seven days to be completed. At the third appointment, veneers are applied. Veneers are first of all temporarily placed on your teeth with water or glycerine to be rehearsed in terms of harmony, shape and colour. Problems in colour or shape can be adjusted. When you like veneers, your doctor cleans your teeth and places veneers on your teeth with special adhesives that harden with a high intensity light source. Things to Be Considered After Treatment: Adverse and strong pressures to your teeth may cause your veneers to dislocate. For this reason, you should not bite your nails, chew pencils, ice, or other hard objects. You can continue brushing and flossing your teeth as before. It will take some time before you can get used to your new teeth and therefore your new appearance. You should visit your dentist regularly to have the condition of your veneers checked.
Full ceramic (full ceramic) full porcelain crowns without metal support
They are made of reinforced porcelain. Although many things affect the appearance of crowns, the most important is their reaction to light. Natural teeth pass light. As a result of this, depth and vitality appear in the tooth. Due to the light transmission properties of porcelain crowns without metal support (full porcelain), their depth and vitality are greater, so the closest results to the natural tooth are obtained.
Since full porcelain transmits light, it creates an aesthetic that is very similar to the natural tooth structure, while there is a dullness and artificiality in metal porcelain, even if it is made very well. For this reason, full porcelain is preferred, especially on the front teeth.
Porcelain with metal support gives the appearance of a dark space in some lights (disco, camera flash, etc.), as if it were not in the mouth. Full porcelain, on the other hand, transmits all kinds of light just like natural teeth.
Porcelain with metal support is mechanically glued to the tooth. Full porcelain, on the other hand, is attached to the tooth mechanically and chemically. Therefore, their retention is much higher compared to metal supports.
Since there is no metal in the substructure, there is no dark line at the crown - gum level. A more aesthetic image is provided.
When the gum is removed, full porcelain retains its aesthetic appearance, while metal porcelain creates a bad appearance in the area where it merges with the tooth.
Against some metals used in the infrastructure (nickel, etc.) there is no allergy risk that may occur in full porcelain.
Zirconium based crowns & bridges without metal support
In aesthetic dentistry, porcelain containing metal is being abandoned day by day. In this system, which has all the properties we want, such as healthier, more aesthetic and more durability, zirconium, a white alloy, is used instead of metal as the infrastructure. We safely prefer zirconium-based porcelain because they are natural enough to be used both on the front teeth and they are robust enough to be used on the back teeth. These systems make the life of the physician and the patient easier and improve the quality of life of people.
What is zirconium?
In classical dental restorations, a metal substructure was used under the porcelain tooth for durability in porcelain applications. Since the disadvantages of this metal substructure in terms of gums, dental tissue, general body health and most importantly aesthetics are known, alternative searches for metal have been made in general. Zirconium, which has previously been successfully used in other areas of medicine, has been opened with the application of porcelain metal instead of flour in dentistry. Because these new zirconium-Decked porcelain veneers stand out from other dental materials with their mechanical resistance, biological compatibility and fracture resistance. It does not cause gum problems and allergies, it allows us to capture aesthetics and function close to natural teeth with its light transmission feature. Crowns (veneers) and bridges made by placing porcelain on zirconium are referred to by the short name CERCON, which consists of combining the words Ceramic and Zirconium. The system with a resistance of 900 Mpa has started a brand new era in dentistry by covering many different indications, tissue compatibility and light transmission feature in addition to the highest physical values. The success of the material has been proven in the field of medicine and industry. as a result of the researches that started in 1998, clinical applications have been started all over the world since the beginning of 2002. With this new application, aesthetic concerns arising in metal-ceramic and full ceramic restorations in the patient are definitely eliminated.
Where can it be used?
Aesthetic crown-bridge studies on single-tooth crown veneers, bridges prepared for back tooth deficiencies, above-implant crowns.
Can teeth be redesigned with advanced computer-aided technology?
While many technical people are almost redesigning their smile, computer-aided applications ensure that the desired teeth and smile are achieved with zero errors. CAD-CAM (computer aided design-computer aided manufacturing) refers to new designs on teeth with the help of a computer. Individuals who are not satisfied with the appearance of their teeth and smile can have the natural teeth and smile they want with these high-tech porcelain systems. The restoration of the teeth is carried out by the dentist and his technician in a computer environment and the teeth are formed from specially prepared porcelain blocks by computer milling technique. The porcelain used in this system has crystal or zirconium in its internal structure, so that excellent aesthetic quality and naturalness are captured. To date, zirconium oxide has not been used in dental applications due to its high cost in production. Thanks to a project developed by the Federal Institute of technology Zurich, zirconium oxide has become economically usable in dentistry. Zirconium has also been used in medicine since the early years, the reliability of the material has been proven by long-term studies. Zirconium has been used for various purposes in various parts of the body, especially for hip joint prostheses, and it has been found that it does not have any side effects or harm, does not cause allergies to date. Zirconium is an element that is resistant to high temperatures, impacts, lightweight, does not conduct heat and electricity, can transmit light. In addition, it is a healthy material that does not cause taste disorders, gum problems and bad breath in the mouth. A wax model of your teeth is being prepared on the model prepared with the measurement taken from your teeth. A computer-aided device prepares the infrastructure of your teeth by eroding the zirconium oxide block in accordance with the information it receives from this model. The work is completed by placing ceramic tiles of the appropriate colour on the structures prepared by etching. Now, strong and aesthetic restorations without metal can be successfully performed with zirconium oxide, a new high-tech product.
What are the advantages for the patient and the physician?
The application time has been shortened. If desired, a person can be given a new smile in a day. The aesthetic quality of the tooth is very high, the light transmittance and posture are like a natural tooth. Since the porcelain blocks used are porcelain blocks previously prepared under factory conditions, the physical properties of the material have been reduced to a minimum, the invariable error margins. It saves time for the physician because the intermediate stages are decayed.
Does the hot-cold sensitivity improve?
No, hot-cold sensitivity does not develop. Because Zirconium Oxide has a heat-insulating property.
Does it cause allergies?
No, Zirconium Oxide is a tissue-compatible substance that does not cause allergies.
Do the gums recede?
No, it has been found that it fits perfectly with the gums in the researches. Of course, it cannot stop gum recession, which develops naturally with age. Since the prepared coatings will be highly compatible with the teeth and gums, gingival recession due to gingivitis will not develop.
What is a smile?
Combining the changes, you want to see in your oral and dental structure with the aesthetics and function of your doctor, to create the most suitable and optimal smile for you. The first acquaintance, encounter and first sight are very important in social relations. A harmonious soft smile is always a positive start. In today's dentistry, special dental designs are made for a natural smile to a person's physique and character. With a small change in your smile, you can create significant changes in your personal relationships and social status, while your psychology improves and your self-confidence increases. When a radiant smile is integrated with your face, your self-confidence and happiness will inevitably affect the other person as well. Smile design has achieved excellent results by combining naturalness and function with the wishes of a person with the increasing aesthetic demand of individuals all over the world and especially in America. Modern dentistry has developed with the new techniques and designs to meet all the aesthetic expectations of physicians and patients. Certain factors that vary from person to person affect your smile.
GİNGİVOPLASTY
Inlay-Onlay fillers (aesthetic fillers)
Porcelain or composite inlay-onlay are fillers with superior aesthetics and durability prepared in the laboratory. We can apply porcelain inlay-onlay instead of composite or amalgam fillings for teeth that require large fillings because it is both aesthetic and durable. Inlay- onlay fillings are preferred because they require less material loss in the tooth compared to porcelain crowns during the construction phase. Only the caries is cleaned and the tooth is measured. Porcelain inlay fillings prepared in the laboratory are then cemented to the teeth with special adhesives (adhesive systems). Especially for teeth with large material loss, root canal treatment is performed first, and if necessary, simple surgical corrections (gingivoplasty - gingivektomy) are performed on the gums, and onlay (porcelain or composite filling prepared in the laboratory) is performed on it. In this way, the risk of fracture of the tooth or filling is quite low.
IPS Porcelain (leucite reinforced pressable porcelain) fillers
They are tissue-friendly fillers, they are one of the materials with the highest biological compatibility. They are produced with advanced technology, the healthy tooth tissue in the mouth is not damaged in the porcelain filling method. With a few changes made on the tooth cavity opened in the normal filling, the tooth is made ready for porcelain filling. In addition, these porcelains are the closest to the hardness of the tooth and the most compatible materials with the gums. Since its hardness is very close to the enamel tissue of the tooth, it does not corrode the teeth like other porcelain, nor does it corrode like composite fillings. Especially in case of large material losses, composite filling or crown (coating) should be preferred instead.
