Metal-free ceramic crowns — are prosthetic structures for restoring lost teeth or correcting defects. Ceramics is the closest to the natural color and structure of the enamel of teeth, so it provides maximum aesthetics and is often used to restore the anterior group of teeth.

Types of ceramic crowns

Ceramic crowns — are the most aesthetically pleasing replacement for your teeth. Ceramics are very close in color, translucency and texture to natural tooth tissue. Depending on your prosthetic goals and budget, different types of ceramic crowns are used:

All-ceramic (porcelain) crowns — highly esthetic but relatively fragile products. They are suitable for prosthetics in the smile area with the lowest chewing load or as onlays for the restoration of small areas of teeth: chips, stains.
E-max crowns made of pressed lithium dioxide ceramic on a zirconia framework. Combines the aesthetics of ceramic — texture and color close to natural, and the strength of metal crowns that can withstand the stresses of the chewing teeth.
Empress crowns made of pressed ceramic with leucite mineral. They look completely natural, but they are not strong enough for chewing teeth.
Ceramics on a framework made of zirconium dioxide — durable prosthetic products. Suitable for the chewing and frontal teeth due to the strength of zirconia and the naturalness of the ceramic.

Advantages and disadvantages of ceramic crowns

Advantages:

Natural smile. Artificial porcelain crowns with high-quality production and careful color selection do not differ from natural teeth and fit perfectly into the smile.
Hypoallergenic. Ceramics do not cause allergies and are not perceived by the body as a foreign material.
Comfort in the oral cavity. The material does not absorb coloring pigments, odors and tastes of foods and does not give a taste in the mouth.
Less turning of the tooth than for a metal-ceramic crown. The tooth does not need to be depulped.
Does not react to temperature fluctuations.
Service life of ceramic crowns 7-10 years

Disadvantages:

The characteristics of ceramic crowns depend on the type of construction. If the crown is all-ceramic, its main disadvantage will be its fragility and narrow segment of installation. Crowns with a zirconium base or E-max ceramic are strong and beautiful, but are much more expensive than all-ceramic or metal-ceramic crowns.

2-6 hours depending on the number of units

Ceramic crown technology

The method of crown production depends on the type of product.
Firing of ceramic mass in vacuum on a refractory model.
Pressing of E-max and Empress ceramics. A mold is made from a wax model of the impression, in which the ceramic material is pressed under pressure and high temperature. This treatment tightly compresses the ceramic crystals to form a very strong structure. The pressed blank is fired and coated with several layers of ceramic.
CAD/CAM milling. The product is milled by a program-controlled machine from a computer model. This method allows you to create the most accurate crown with a perfect fit to the tooth base and side teeth.

Getting used to the crown and care

Some problems may arise during the period of soft tissue recovery after the denture and while the patient is getting used to the structure. For example, the prosthesis may interfere with the habitual closing of the jaws (due to the long-term absence of a tooth of normal anatomical shape). In some cases, there may be inflammation of the gum, pain, redness. All this is normal, because there was traumatization of the gum, because it was necessary to align the position of the mucosa along the contour of the crown. But if the discomfort does not just persist, but increases, you should tell the doctor about it. And as soon as possible.

It is possible to avoid unpleasant sensations, if in the first days after installation of the prosthesis to observe a gentle regime: carefully brush your teeth with a soft brush, take food in a pureed form.

The care of metal-free ceramic dental restorations should be the same as regular dental care:
It is important to perform daily oral hygiene with mandatory brushing with toothpaste.
After eating, it is recommended to carefully remove food residue from the place of contact between the tooth and the gum and from between the teeth. After eating, rinse your mouth with water or a special mouthwash, and floss between the teeth.
Toothpaste with a high degree of abrasiveness is not recommended for the care of metal-free ceramics.
Chewing on hard objects (nuts, ice, seeds) is not recommended
