Features of zirconium crowns on teeth, reviews from real users of zirconia crowns

The industry of modern dentistry is not standing still.To date, there are many options for prosthetics.Many of them can be a worthy replacement for teeth, both in physiological properties and in terms of aesthetics.Outside of any competition for matching the dimensions of teeth and the precision of manufacturing are zirconium crowns.

Crowns made of zirconium dioxide

These are heavy-duty tooth structures that are manufactured with the help of high-tech modern equipment and can be applied to the front and side chewing teeth.

Zirconia is a material that is today considered to be one of the best quality .You can make from it not only single crowns, but also bridges.

Zirconia crowns are made of two layers:

1. The inner layer( high-strength frame) is made of zirconium dioxide.
2. Outside - porcelain mass, sintered on the basis of the frame.

On the strength of this skeleton, very little is inferior to the metal base , while possessing the ability to pass the light necessary to achieve the translucency that is characteristic of the enamel of natural teeth.In turn, prostheses made of cermets are deprived of such translucency, since their inner frame is metallic and does not let light in at all.This affects the aesthetics.

Advantages of zirconia crowns

• Crowns convey transparency and shades of natural tooth enamel.
• Over time, the ceramics do not change, that is, it does not lose shine, does not dim and does not darken.
• Zirconia teeth are very reliable and have a long service life.The structure of this material has high strength.And thanks to the CAD / CAM technology used for the manufacture of prostheses, it is achieved high accuracy of their fit and fitting to the turned teeth.This reduces the possibility of caries development on the border of the tooth with the crown and the ingress of saliva and microorganisms under the crown.
• The structures of this material are hypoallergenic.
• Absolutely safe for the gums and the body as a whole.
• No strong turning of teeth is required.
• There is no gray staining on the gum border with the crown.

Since zirconia is an incredibly strong material, the life of structures made from it is unlimited.

Have zirconium crowns single minus - high price.This is explained by the complexity of the technological process, which requires appropriate technical equipment, and a high cost of consumables.However, in return, the patient receives aesthetics and the highest quality.

Contraindications

• Disturbance of occlusion.
• Weakness of the patient after the disease.
• Mental disorders.
• Pregnancy.
• The presence of inflammatory processes in the oral cavity.

Manufacturing of zirconium crowns

designs are manufactured using CAD / CAM technology.

Stages of manufacture

1. A three-dimensional model of the future crowns is loaded into the computer milling machine and the frame of the structure is manufactured.
2. To impart strength to the dental structure, it is fired in an oven.
3. The porcelain mass is layer-by-layer applied to the made skeleton.Each of the layers is sintered in an oven.
4. On the last layer, before its firing, a special painting compound is applied, which gives the crowns the desired shade.

Since the process of manufacturing zirconium crowns is completely automated, possible errors are excluded .

Installation of crowns

• First of all, the dentist prepares the patient's supporting teeth: replaces the old fillings, heals caries, seals the root canals.
• Next, for the thickness of future crowns, supporting teeth are grinded and scanned in a special computer program.Scanning is necessary in order to create a three-dimensional model of future crowns.
• The shade of the structure is selected.
• Temporary plastic crowns are manufactured and installed.

Once the zirconium structures have been manufactured, their tries on and fixes the .At the doctor's discretion, fixation can be temporary or permanent.

Patients, after installing zirconium constructions, may complain of feelings of discomfort and increased sensitivity of the turned teeth.In these cases it is necessary: ​​

• It is compulsory to comply with all the recommendations of the doctor for oral care and the installed structure.
• For some time, do not eat solid foods.
• Patients suffering from bruxism should use a nightcap.

Necessary care

Two times a day the teeth should be cleaned with toothpaste and brush .

The mouth is preferably rinsed with water after each meal.

Dental spaces should be cleaned from food residues with dental floss( floss).

It is not recommended to crack solid objects such as seeds, nuts, ice and others.

The doctor should be visited twice a year for preventive examination.

According to a large number of patients, zirconium crowns are an excellent option for prosthetics.
