What is a dental crown

The visible part of a natural tooth is the crown. It is most often destroyed due to caries, trauma or the process of demineralization. It can be restored with an artificial prosthesis - a dental crown. It can be temporary - for the period of treatment, or permanent - for every day. In some cases, crowns are used to correct the shape of implants when they are damaged.

Self extraction

Self-extraction is not recommended. Using tools that are not intended for this purpose (pliers or wire cutters) can lead to injury to the mucous membranes and breakage of the tooth stump.

But there are cases when the microprosthesis has completely separated from the tooth and is loose, or even broken into pieces, which creates a danger of swallowing it along with food. In this case, you need to remove it and visit a doctor as soon as possible to install a new microprosthesis.

In the video, the dentist will tell you what harm old crowns cause to your health.

Contraindications

Like any medical procedure, the installation of crowns has contraindications. Cases in which the procedure is not performed:

• advanced periodontitis;
• bruxism - teeth grinding;
• fragile enamel;
• teeth are small and poorly positioned;
• pathological bite, when the incisors overlap one another.

Sometimes the age of the patient may be a contraindication to installing a crown made of a certain material. Then he is offered another way to restore the integrity of the dentition.

Types and degrees of curvature

The method of restoring crooked teeth depends on the degree of curvature and the age of the patient. On the Internet you can find many photos of celebrities with crooked teeth before and after restoration. How does the correction process work?

First, let's look at the degrees of curvature:

• First degree: refers to individual teeth that differ from the rest in shape, size or location.
• Crooked teeth 2 degrees: incorrectly formed dentition due to the simultaneous eruption of several teeth at once.
• Third degree: curvature at the level of the jaws, which leads to improper closure of the upper and lower dentition.

In addition, the front teeth, incisors or wisdom teeth may be crooked. The front ones, as a rule, change shape or location due to external factors: injuries, the habit of chewing a pen or seeds.

Orthodontist Anastasia Sergeevna Arkhangelskaya from the 32 Dent clinic explains why teeth grow crooked in adults: “In adulthood, people often have to have their teeth removed. If an implant or other prosthesis is not installed in their place, the dentition may become crooked. In addition, the development of dental anomalies is facilitated by the eruption of wisdom teeth. This is especially true for people with a narrow jaw, which simply does not have enough space for large wisdom teeth.”

What are they: materials

Crowns are made from different materials: some are more durable, others are only suitable as a temporary measure. Their cost, complexity of manufacturing and installation also depend on this.

Metal ceramics

The product has a metal frame and is covered with ceramics on top.

Metal-ceramic crowns are suitable for installation only in adult patients.

Metal composite

The crown frame is made of an alloy of chromium and cobalt. From above it is covered with a photopolymer composite: while it is soft, it is given a shape, after which it is fixed with UV rays.

People with metal-composite crowns need to follow a diet to prevent artificial teeth from changing color. It is not recommended to consume drinks with dyes and foods with a high pigment content.

Golden

The oldest material for making crowns is gold.

It is best to install gold crowns on the back teeth, where they will be almost invisible.

Zirconium dioxide

Modern material for crowns is zirconium dioxide. It is durable, aesthetic, does not cause allergies and lasts a long time. But it has a fairly high cost, so it’s not suitable for everyone’s budget.

Metal-free

Modern synthetic materials can completely replace metal in the composition of the crown. They are no less durable, and look as close as possible to natural teeth.

Ceramic

The best way to choose the color of a crown is when it is made of ceramic. They do not look artificial, as they are quite transparent.

They are great for replacing incisors. But for chewing teeth, ceramic crowns are too fragile and cannot withstand such a load.

Porcelain

Porcelain crowns are not so popular, but are gradually becoming more and more in demand. They are easily and firmly fixed, which reduces the risk of loosening. Porcelain products last a long time, do not deteriorate due to temperature changes and are not stained by food. In this case, the crown can be made in an anatomical shape, repeating the relief of the tooth as accurately as possible, which ensures comfortable wearing. They look very aesthetically pleasing and are also hypoallergenic.

One of the disadvantages is their loose fit to the tooth, which can cause cervical caries. Crowns are quite fragile and can destroy adjacent healthy teeth. The product is not suitable for patients with thin enamel. In addition, the cost of such crowns is quite high, which is not affordable for everyone.

Combined

By combining several materials, it is possible to create crowns that combine their best properties. The product is suitable for use on front and back teeth: they look aesthetically pleasing and can withstand chewing loads. But such crowns are short-lived because they quickly wear out and sometimes become deformed. But their installation does not cause a blow to the budget.

Plastic

Plastic crowns are used as a temporary measure. They are manufactured on site and installed on the same day in place of the extracted or treated tooth. The cost of such crowns is low. But it is impossible to use them as permanent ones, since they cannot withstand prolonged chewing load.

Types of crowns

The number of missing teeth, the presence of dentures and other individual characteristics of the patient determine what type of crown is suitable for him. It is impossible to determine this in absentia, since it requires an examination by a specialist.

Bridges

Suitable for people who have lost more than one tooth. The prosthesis is made for all missing units, and its parts are connected by a metal bridge. To secure the crowns, you need healthy chewing teeth. Only complex prosthetics are performed in this way.

Implant supported crowns

If the patient has implants, the crown can be secured to them. This will prevent the destruction of healthy teeth, which can occur due to excess stress. But the method is only suitable for those who already have implants installed.

Crown for one tooth

If one tooth is destroyed, a crown can be installed only on it. This usually happens after deep caries or injuries. Before installing a crown, the condition of the periodontium, jaw and gum tissue is assessed. Sometimes additional operations are performed to build up the bone plate.

Fixation with a pin

The rarest method of prosthetics is installing a crown on a pin. It is quite traumatic and carries a risk of complications, so it is almost never used. If other methods of prosthetics are not available to the patient, the crown is installed on a pin, but this is done in several stages under the supervision of specialists at each of them.

What are the consequences of untimely crown replacement?

1. Destruction of the tooth under the crown with its subsequent loss.

The main function of a crown is to restore a badly damaged tooth and protect it. The first time after installation, the crown performs its function perfectly. But after a certain time, changes occur. The gingival margin rises, saliva and gingival fluid affect the cement that “secures” the crown. Over time, this cement can be partially washed out (dissolved), a microscopic gap is formed between the crown and the tooth, and the tooth begins to deteriorate under the influence of microbes and oral fluid. The most insidious thing is that these signs occur asymptomatically and unnoticed by the patient, since they are painless. Therefore, replacement of crowns often occurs untimely, when the tooth is destroyed too much and becomes simply unreliable.

Associated with this is the myth that teeth under crowns are destroyed. The truth is that crowns are simply replaced at the wrong time, but too late.

This can be prevented by timely replacement of the orthopedic structure.

2. Inflammation of the tissues around the crown . This means the gums, tooth ligament and bone tissue. A poor-quality crown can lead to the formation of a chronic inflammatory process in the gums (gingivitis, periodontitis), which is manifested by redness, bleeding when brushing teeth, aching pain in the gums and an unpleasant odor. If such a crown is not replaced for a long time, the underlying tissues become involved in the inflammatory process, which may lead to the formation of bone pockets, disruption of the ligamentous apparatus of the tooth, and local periodontitis, which in severe cases leads to tooth loss.

Important! Make it a rule to visit the dentist for a preventive examination at least once a year, if you have any dentures, in order to notice their failure in time and prevent or correct the problem.

Methods for making a crown

Orthodontic products can be manufactured using several methods. Each of them has its own advantages and disadvantages.

Cast products

Strong and durable crowns are made using casting. For this, a single piece of metal is used. The method is not suitable for all materials.

Stamped

More affordable, but less durable prostheses are made by stamping:

• a mold is placed into the dental anvil;
• using rubber rings a stamp is obtained;
• the crown is made using special hammers that differ in shape and size;
• The product is given its final shape using small tongs.

Such crowns last less than cast ones, but are much cheaper to produce.

How a tooth crown is made

Before starting to make the prosthesis, the size and shape of the product are determined. To do this, the patient undergoes:

• examination by a doctor;
• general and targeted x-ray diagnostics;
• 3D - visualization on a computer screen of the entire jaw and a specific tooth.

Then the doctor selects the material from which the crown will be made. It depends on which tooth needs to be replaced, the age of the patient and his financial capabilities.

To accurately manufacture the prosthesis, an impression of the jaw is taken. For this, gypsum or a similar synthetic material is used. The resulting model is sent to the laboratory.

Preparing for installation

A crown cannot be placed on an unprepared tooth. He must be completely healthy. If you have inflammatory diseases of the oral cavity, they need to be cured before installing a crown.

Then the teeth are ground down. It is performed under anesthesia, so the patient does not experience any discomfort. This procedure is carried out to ensure that the denture fits perfectly and no food remains get stuck under it. It also allows you to equalize the width of the neck and middle of the tooth. This way the prosthesis will be firmly fixed, which will prevent loosening.

Only 1-2 mm of enamel is removed. The depth of treatment depends on the selected crown material: metal-ceramics require more space, and ceramics are quite thin; a very thin layer is removed to install it.

In some cases, depulpation is performed. The patient is warned about its need in advance.

If the tooth is severely damaged, a core inlay is installed. It separates the internal tissues from the crown, allowing you to avoid pain while wearing it.

Upon completion of all manipulations, a temporary crown is installed on the tooth. It is made in the dentist's chair. The design protects the prepared area and restores its aesthetic appearance.

Composite veneering as a way to correct crooked teeth

Composite restoration is called composite veneering, but this procedure has many differences from installing onlays on teeth.

• Composite restoration is the most affordable way to correct crooked teeth for adults and children. Depending on the amount of material used, the cost will vary between 3500-5500 rubles.
• Only the problematic tooth is subject to intervention. Other units are not turned.
• You can correct crooked teeth with composite in one visit.
• The durability of composite restorations is inferior to ceramic prostheses (veneers or crowns), but with high-quality care and careful handling, a new “straight” tooth will last a long time.

Installation process

The crown is installed in several stages. The number of visits to the doctor depends on the condition of the teeth and the chosen prosthetic method.

Laboratory stage

A cast of the patient's jaw is sent to the laboratory to create a plaster model of the jaw. After complete drying, the desired part is cut out. Using it, a wax prototype is made.

The model is fixed on the base and filled with a special mixture. It goes into the oven for 4-5 hours. The resulting mold is immediately filled with the alloy while it is hot. The future crown is left in this form until it hardens completely. The piece is then polished and sanded to achieve the perfect shape.

Removing the temporary structure

When the permanent crown is ready, the temporary structure is removed. It only takes a few minutes, after which prosthetics can be applied.

Installing a crown on a tooth

Before fixing the crown, a fitting is performed. If it is uncomfortable or the enamel color is not suitable, it is sent for revision. When the crown is perfect, it is secured with cement. The strength of the fixation must be checked after the material has hardened.

Monitoring the situation after installation

After fixing the crown, the doctor checks how correctly it is installed. To do this, an x-ray is taken. Only after his assessment can the patient go home. If you experience strange sensations, you should call your dentist to clarify your condition and the need for a second visit.

Our advantages

At the Beryozka clinic, the material for the crown and its type are selected individually. Each patient is given an approximate treatment estimate so that he can clearly see what he is paying for. A transparent work system, professionals, the latest equipment and materials ensure the ideal result of prosthetics at the Beryozka clinic. A polite attitude and the ability to quickly get an appointment are the key to pleasant emotions from visiting a dentist.

Pros and cons of crowns

All medical procedures have both pros and cons. Before you decide to install crowns, you should compare the pros and cons.

Advantages

The advantages of using this method of prosthetics are much greater than the disadvantages. The advantages of installing crowns include:

• preventing the destruction of pulpless teeth;
• preservation of a living tooth even with partial destruction;
• restoration of the ability to chew food normally;
• restoration of an aesthetic appearance while smiling;
• prevention of diseases of the gastrointestinal tract, which can be caused by insufficient chewing of food;
• restoration of the ability to speak clearly.

Due to the large number of advantages, the procedure has become so popular among patients.

Flaws

The procedure for installing crowns has its disadvantages. Flaws:

• the need to grind healthy parts of the tooth;
• limited period of wearing a prosthesis;
• inability to carry out the procedure with a damaged root;
• the need for regular visits to the dentist for monitoring.

The disadvantages of the procedure are offset by its advantages. Therefore, crowns remain the most popular way to restore the integrity of the dentition.
