What are porcelain crowns?
Such constructions have recently begun to be used in prosthetics. They are made from pressed ceramics that undergo special processing. The peculiarity of the material is that there are no metallic impurities in its composition. Such constructions allow restoring a lost tooth. It will not differ from the rest, and its appearance will be even more attractive.
Due to their high aesthetics, porcelain structures are in particular demand among patients. Of course, in terms of strength, they are somewhat inferior to cermets. Therefore, porcelain crowns are often installed on front teeth. This is due to the fact that in this case, the prostheses will experience a slight load and will show themselves to the maximum in terms of aesthetics.
Porcelain structures have sufficient strength and keep their shape well. Throughout the entire service life, they do not lose their original color. Products are easily attached, which greatly simplifies prosthetics.
Indications and contraindications
Before installing crowns, it is worth considering the indications and contraindications. It is recommended to use constructions in such cases:
- High sensitivity to plastic. Porcelain products are inert to the human body, which eliminates the risk of an allergic reaction.
- There is a need for anterior and posterior teeth prosthetics.
- The presence of a tooth that has completely collapsed.
- Need in restoration several teeth that are located in the neighborhood.
- The patient is allergic to metals, which makes it impossible to carry out prosthetics metal-ceramic designs.
As for contraindications, it is not recommended to use porcelain products in the presence of such pathologies and problems:
- complex form periodontal disease;
- malocclusion;
- low hardness of the enamel.
Dental prosthetics should start with a consultation with a doctor who can determine the relevance of using porcelain constructions in a particular case.
Types of porcelain crowns
Depending on the location, the crowns are divided into lateral and anterior. In addition, structures are classified according to the features of attachment to the base. With this in mind, two types of porcelain can be distinguished:
- Crumb structures. To fix the tooth, a special metal crampon wire is used. Various metals are used to make wire. But, most often it is an alloy of silver and palladium. They are used to restore the anterior teeth.
- Hole structures. There is emptiness inside them. They are often used for the restoration of lateral dental units.
Da Vinci crowns are distinguished into a separate group. Such structures are made of porcelain using a special technology. Their difference is that they can transmit a stream of light through themselves. Thanks to this, they are as similar as possible to real teeth.
Advantages and disadvantages
Porcelain dentures have certain advantages and disadvantages. The advantages of these products include:
- Aesthetics and maximum similarity to natural dental units. This is achieved thanks to the unique structure of the material used to make the crowns.
- The products have the necessary thermal conductivity, which makes it possible to reduce the sensitivity of dentures to temperature changes.
- They do not cause allergic reactions, which is explained by the absence of metal in the composition.
- Porcelain products can have a different shade. This makes it possible to create a structure that will fit into the dentition as much as possible.
- Throughout the entire service life, the prosthesis retains its original color. It does not darken.
- Due to its lightness, people quickly get used to the material.
Unfortunately, these designs have some disadvantages. Among them it is worth highlighting:
- Porcelain is a rather fragile material. Therefore, it is not used to make bridges.
- The crown does not adhere well to the gums, which can cause some problems in the future.
- The high abrasiveness of the material negatively affects the condition of the adjacent teeth.
- Compared to polymer and metal products, a porcelain crown is quite expensive. Therefore, not everyone can use this method of prosthetics.
Despite all the shortcomings, porcelain designs are very popular among the population.
How porcelain crowns are made
Making porcelain crowns is a rather complicated process that takes place in several stages. Only a qualified specialist can do it correctly. The main stages of prosthetics include:
- dissection problematic dental unit;
- making an impression;
- making a model;
- cap formation;
- structural modeling;
- firing the product;
- fixation of the prosthesis to the stump.
The manufacture of the prosthesis is carried out using a platinum cap, which is covered with a special foil. It is located exactly without a single fold. The cap is placed in the impression. After that, the selection of the required shade of the design is performed. The prosthesis should be maximally compatible with other dental units.
At the next stage, the porcelain mass is applied to the cap. When the blank is formed, the cap is removed. The product is processed with a special compound, which protects it from weight loss during firing.
First of all, the product is fired from the inside, which allows you to eliminate all kinds of cracks. This is followed by vacuum firing. After that, the workpiece is preformed. At the next stage, the structure is adjusted to the required dimensions. It is given individuality by performing natural curves as well as stains.
At the final stage, the product is painted and glazed. This is a layer-by-layer production. Also, such crowns are made of pressed ceramics. The mass is pressed and fired. The peculiarity of the product is that it has high strength.
Installation steps
Installation is carried out in stages:
- Dissection and production of an impression, according to which the structure is subsequently manufactured.
- When the crown is ready, it will be tried on. If necessary, the prosthesis is corrected.
- If everything suits the patient and the doctor, then it is installed directly. Fixation is carried out using a special cement composition.
The cement used during the installation should be as natural as possible to combine with other dental units.
Care and service life
To ensure a long service life of structures, it is necessary to treat them with care. A small crack can lead to complete destruction of the prosthesis. Therefore, experts recommend careful handling of solid foods and regular cleaning of the oral cavity.
The product is not exposed to caries. But, if plaque penetrates under the edge of the gums, it will lead to damage to the dental stump. To prevent this problem, experts recommend cleaning after every meal. To do this, use a fluoride paste, as well as an anti-inflammatory rinse.
The service life of the prosthesis is on average 15 years. Of course, it all depends on how accurately the patient adheres to the doctor's recommendations. For example, the use of solid foods, strong clenching of the teeth, inadequate care and sudden changes in temperature can lead to a reduction in the life of the prosthesis.
Comparison of porcelain with other materials
Porcelain teeth have their positive and negative sides, so it is important to compare dental porcelain with other prosthetic materials and choose the most suitable one.
Plastic or porcelain
If you compare plastic and porcelain crowns, you will notice many differences. So, polymer structures have certain advantages:
- low fragility;
- ease of grinding and processing;
- reliability and ease of installation.
But, as for porcelain products, they are not inferior to polymers and have certain advantages:
- preservation of the original sizes and shapes throughout the entire service life;
- high hardness, which eliminates the rapid abrasion of the surface.
As for the disadvantages, it is worth noting that porcelain products are very difficult to process. So, if you overheat them, it will lead to the formation of cracks.
Sintered metal or porcelain
To determine what is better for cermet or porcelain products, you should pay attention to the following features:
- Porcelain structures are several times more expensive, but their service life is much longer.
- Sintered metal requires significant turning and can cause an allergic reaction.
- Porcelain dentures have an aesthetic appearance and are used to restore both posterior and anterior teeth. The cermet is installed mainly instead of the lateral dental units.
- Sintered products do not need special care, which cannot be said about porcelain counterparts.
When making a choice, you must also take into account the cost of the product, the price of porcelain teeth depends on many factors. In the process of prosthetics, a number of procedures are carried out, which are paid separately. But, if we talk about the structure itself, then its price is in the range from 13 to 21 thousand rubles. rubles.
Patient opinions
When choosing, it is also worth considering the reviews of patients who have already experienced prosthetics with porcelain crowns.
When the need arose for the restoration of the anterior teeth, I thought about which crowns to choose. The doctor advised porcelain products. I agreed and for good reason. The result completely satisfied me. In the future, I will use only such prostheses.
