Zirconium

Zirconium is a white alloy that can be used as an alternative to the metal in the substructure of porcelain in classical crown-bridge prostheses. The usage areas are quite wide. In the restorations of teeth with too much material loss, in cases of diastema (the space between two teeth), if the patient does not want orthodontic treatment, in cases where there is severe discoloration, if sufficient results cannot be obtained with tooth whitening, in the removal of mild crookedness (orthodontics is not desired), in cases where tooth lengthening is performed. As a bridge in old filled teeth with discoloration and structure, in cases where there is a missing tooth in the posterior teeth ( implantIf not preferred), it can be used in anterior group implant-supported prostheses and in regulating smile aesthetics.

Why is zirconium preferred?

Due to the very good light transmittance of zirconium, an aesthetic appearance close to natural teeth can be achieved. Due to the metal used in the infrastructure of classical porcelain, this transparent and aesthetic appearance cannot be fully achieved, the teeth appear more opaque. With zirconium, all these are prevented. In addition, since zirconium is a tissue-friendly material, its compatibility with the gingiva is very good. The purplish appearance seen on the gingiva in the neck area of ​​the tooth in metal porcelain never occurs in zirconium. It does not cause gum recession.

Will there be any discoloration on zirconium teeth over time?

Since the porcelain on the outer surface of zirconium teeth is smooth and slippery, it is not affected by colorants such as cigarettes, tea and coffee. Therefore, there is no color change.

How are zirconium teeth prepared?

After the necessary planning is done in the mouth, the teeth are cut (the teeth are reduced a little). Then a precise measurement is taken from the mouth and sent to the laboratory. In the laboratory environment, a zirconium substructure in a color suitable for the tooth and suitable porcelain are processed on it. And zirconiums prepared in the clinical environment are applied (pasted) to the patient’s mouth. These are fixed type prostheses. Attaching and removing is not possible. They are prostheses that we can easily use without being distinguished from our natural teeth.

Is pain felt during the construction of the zirconium process?

The preparation (tooth cutting) applied to the teeth for making zirconium is a procedure performed under local anesthesia. Therefore, no pain is felt during the procedure. After the procedure, a temporary coating is applied to the teeth and the sensitivity that may occur in the cut teeth is prevented. Some hypersensitive people may feel a slight tingling despite the temporary teeth, but this rate is very low. Usually, the procedure is completed painlessly.

Is root canal treatment necessary for every tooth to be made zirconium?

Root canal treatment is not required for every tooth to be made zirconium. If there is a deep caries or fracture in the tooth to be prepared, these are treated first. In the meantime, if necessary, root canal treatment is applied to the tooth, and then the tooth is cut and the veneer is prepared with zirconium material. Or, sometimes, the vascular nerve package of the tooth may be opened during tooth cutting, and in such a case, root canal treatment should be performed. However, otherwise, the tooth is tried to be preserved alive. Root canal treatment is not performed for every cut tooth.

How long does the zirconium process take?

If the patient does not have any gingival problems, the procedure is completed in an average of one week. If there are already gingival problems, the gingiva should be treated before the zirconia is made. After the end of the treatment, a period of 4-6 weeks is allowed for the gingiva to heal ( flap operation post). Then, since the gingival levels are fixed, the zirconium coating process can be started.

At what age can zirconium be applied to individuals?

Zirconium teeth can be applied to almost every age group. However, zirconium crowns made up to the age of 18 may require frequent replacement, as gaps will occur between the teeth in direct proportion to the growth and development of the jaw. For this reason, it is not recommended for those between the ages of 18-20.

Are zirconium teeth durable?

Zirconium-based crown-bridges are as durable as metal-based crown-bridges. It is less fragile than porcelain. Because porcelain is better adapted to zirconium, porcelain fractures are less common in zirconium-based prostheses.

In which situation is zirconium not preferred?

If there are long toothless areas in the posterior regions, zirconium is not preferred due to increased fragility.

How much material must be removed from the teeth in order to make zirconium?
The loss of material in the teeth is higher in zirconium than in porcelain laminates, it is almost the same as in metal-based porcelains. (1-2mm)

How long do zirconium teeth last?

Normally, the average lifespan of each crown-bridge restoration is 5-7 years. However, any tissue change ( gum recession ), if the patient’s oral hygiene is good, if no damage has occurred to the zirconia, it can be used for longer years. All these require regular dental check-ups. It is recommended to visit your dentist regularly every 6 months and have the necessary controls done.

How to care for zirconium?

Teeth with zirconium coating should be brushed regularly just like natural teeth. Dental floss should be used, special dental floss that we call superflos (for cleaning under the bridge) should be preferred under the body. Even if all the teeth in the mouth are covered, regular tartar cleaning ( Weighing ) should be applied. For this, a dental check-up every 6 months is recommended.
