Metal ceramics in Krasnoyarsk - March

A crown is a dental prosthesis that imitates a real tooth. Its goal is to preserve what is left of the damaged tooth or replace it. In the case where there is no tooth at all, a pin or stump tab is inserted into the root canal and a crown is secured to it. If there is a tooth, but it is in unusable condition, then they try to cure it, fill the root canals, grind it down on all sides by 1-2 millimeters and then put a crown on it. A crown is placed if a tooth is destroyed by more than half (especially if it is a “dead” tooth from which the nerve has been removed), if the tooth tissue is prone to excessive abrasion, if it is necessary to correct visual imperfections - for example, to hide a gap between the teeth. Crowns vary in the type of material used - usually metal alloys, ceramics and combinations thereof.

Metal-ceramic crowns

The installation of a metal-ceramic crown is performed when there is a significant violation of the integrity of the tooth, when therapeutic treatment is no longer advisable.
Metal-ceramic crowns are a particularly durable orthopedic structure on a metal base. It is distinguished by high performance, long service life, high strength and aesthetics.

Metal crowns

Installing metal crowns has many advantages. They are comfortable, durable, have minimal negative impact on nearby healthy teeth, are resistant to corrosion, have high strength and biocompatibility. Their main disadvantage is their unaesthetic appearance, which is why metal crowns are not installed on the front teeth. But they are great for chewing teeth. A contraindication to the installation of metal crowns may be an allergy to certain types of metal, as well as the risk of a galvanic effect. Crowns of this type are made from alloys of precious metals. Silver-palladium and gold alloys are used. Gold is not used in its pure form because it is soft and therefore short-lived. The advantage of alloys is hypoallergenicity; from alloys of other metals. Steel, steel coated with gold, chrome, cobalt are used. Such crowns last for decades and can withstand heavy chewing loads. Please note that you cannot use crowns made of several metals at once. If you have installed steel once, then in the future you will have to turn to this metal. Otherwise, galvanic reactions may occur in the mouth, which will manifest as a burning sensation and a metallic taste.

pros

Durability;
strength;
affordable price.

Minuses

Unaesthetic appearance;
may cause galvanic reactions (burning, metallic taste)

Metal ceramics in dentistry

The method of replacing one or more units of the dentition is called prosthetics. There are many materials from which a prosthesis can be made, they differ in cost, strength, and aesthetics.

One of the most versatile and popular materials for prosthetics, as already mentioned, is metal-ceramics .

This is due to the fact that the material is similar in structure and physical properties to natural enamel. In the dental dictionary, metal-ceramics means the manufacture of crowns and bridges , the frame of which is made of metal and the surface is coated with ceramics. The use of alloys made of expensive metals allows the highest quality of the frame to be achieved. The shape of the frame is exactly similar to the tooth being replaced.

The technician covers the surface of the frame with ceramic cladding. The advantage of the material in this case is the ability to select the shade of the coating to match the enamel of the remaining teeth. The finished prosthesis is hypoallergenic and compatible with oral tissues. Sometimes, in rare cases, allergies can trigger a reaction to the material. Then the metal-ceramic crown is replaced with a completely ceramic one without metal inserts, for example, all-ceramic E-max crowns. Which completely eliminate the possibility of allergic reactions.

The scope of application of metal ceramics is the manufacture of dentures for chewing teeth , due to the strength of the final structure, but it is also used for the anterior groups of teeth.

What is the service life of a metal-ceramic crown?

The quality of a metal-ceramic crown is largely determined by the properties of the alloy from which the prosthesis frame is made; it is this that is responsible for the strength of the structure as a whole. The alloys from which crowns are made in our clinic have a service life of at least 12-15 years .

Types of bridges

Types of bridges include artificial teeth of varying cost and materials. The most popular are metal-ceramic and ceramic bridges. Both types are characterized by strength. Such crowns are reliable, biocompatible, do not cause allergies and do not cause harm to health. The service life of these dentures is more than 5 years, which allows patients to completely forget that some teeth have been replaced with artificial ones.

In the case of installing metal-ceramics, a metal base made of gold, chromium, cobalt, platinum or a combined alloy is installed first. The metal is then coated with a layer of ceramic that exactly replicates the shade and quality of real tooth enamel.

Ceramic dental prosthetics is possible when there is a small, up to 2/3 of the total size, fragment of a destroyed tooth. The ceramic structure, specially created in the laboratory, is indistinguishable from a real tooth and is made in accordance with the individual characteristics of the patient, even replicating the natural transparency of the enamel.

Prosthetics of anterior teeth

Prosthetics of the front teeth with metal-ceramic crowns is possible, but there is a high probability of the metal crown being visible through a thin layer of ceramic in the visible zone, which significantly affects the overall aesthetic appearance of a row of teeth. It is used according to the patient’s decision, or when it is impossible to restore the integrity of the tooth using filling materials and onlays. For prosthetics of the smile area, all-ceramic crowns or ceramic crowns on zirconium dioxide are more suitable.

At the client’s request, to install metal-ceramic crowns on the front teeth; with proper care, the service life of the dentures is at least 10 years.

Strength

Metal-ceramic crowns and bridges are highly durable, which is why they are most often installed in the chewing area of the dentition. Recently, crowns on a frame made of zirconium dioxide and aluminum dioxide have gained great popularity. They are installed not only on the chewing teeth, but also on the front teeth.

Allergic reactions

Ceramic coating on the surface of the crown is absolutely hypoallergenic and is well tolerated by the body. The metal alloy from which the frame of the denture is made may contain metal, which in rare cases causes an allergic reaction.

It is necessary to pay attention to allergy symptoms in time:

burning in the mouth,
swelling of the gums near the crown;
metallic taste.

If after installing the structure the following signs are noticed, you need to contact your dentist and replace the denture with an all-ceramic one.

Zirconium dioxide (ceramics based on zirconium dioxide)

The zirconia crown base has a color that imitates the color of the tooth and has high light transmittance. The zirconium dioxide frame is lined with ceramics, and the tooth on which such a crown is installed looks natural and aesthetically pleasing.

pros

The highest aesthetic indicators;
biocompatibility;
do not cause allergic reactions.

Minuses

High price.

Metal ceramics or ceramics?

The determining factor when choosing a material for a prosthesis is its direct function: strength or aesthetics. To replace a chewing tooth, a more durable material is required, but its aesthetic qualities fade into the background, since it is located behind the smile area. In this case, a metal-ceramic crown . When making anterior dentures, aesthetics are important; the beauty of the smile will depend on the crown, so all-ceramic dentures are preferable.

Aesthetics

When installing metal-ceramic prostheses, the compliance of the design with aesthetic indicators is of great importance:

Correctly chosen color;
The shape of artificial teeth corresponds to the anatomical shape of natural teeth;
The organic combination of a denture with natural teeth is achieved by choosing the right shade of dye for the incisal edge, interdental spaces and cervical area.

Metal ceramics look very aesthetically pleasing and do not differ from natural teeth.

Ceramics

Ceramics has high aesthetic values. Such teeth cannot be distinguished from real ones. The following materials are used in the manufacture of crowns: Pressed ceramics (porcelain). Such crowns provide the highest aesthetic results, but they are also the most fragile. Ceramic crowns last an average of 5 years.

pros

High aesthetic indicators;
biocompatibility.

Minuses

Fragility;
fragility.

Types of metal-ceramic structures

Metal-ceramics is a multifunctional material from which the majority of orthopedic structures can be made, which will help solve many dental problems. These include:

Bridges and crowns - applicable when it is necessary to restore from two to four units of the dentition in the front or side;
Restoration of damaged parts of teeth as a result of external damage;
Abrasion of tooth enamel;
Supports for temporary dentures;
Correction of other aesthetic defects.

Advantages of metal-ceramic prosthetics

The most important advantage of metal-ceramic crowns is their long service life ; they do not wear down while chewing food. If you regularly visit your dentist and are attentive to oral hygiene, your denture will last at least 15 years.

To make metal-ceramic crowns, it is possible to use a large number of metals and their alloys of different prices, which makes prosthetics more affordable.

If the ceramic coating on the prosthesis is done with high quality, the patient can be sure that the metal-ceramic crown will not stand out from the row of “natural” teeth.

With properly performed prosthetics, the process of chewing food does not cause any unusual sensations, the difference between natural teeth and dentures is not noticeable.

There is no accumulation of bacteria on metal-ceramic teeth; this is especially important for patients with periodontal disease.

With the help of metal-ceramic dentures, it is possible to restore damaged teeth even in severe advanced cases. The metal-ceramic crown is so durable that the appearance of cracks and chips is practically excluded. After installation of the prosthesis, the patient can chew hard vegetables and fruits without fear. Keeping the crown in its original form does not require much effort. To do this, simply brush your teeth twice a day and visit a dental hygienist every six months.

Disadvantages of metal-ceramic crowns

Despite the advantages, there are a certain number of disadvantages of metal-ceramic prosthetics:

The need to depulp the tooth, which leads to some fragility in the future;
Due to the large thickness of the structure, the hard part of the tooth is subjected to significant excision and grinding;
It is impossible to install metal-ceramic crowns in the absence of a large number of teeth.

Metal-plastic crowns

Metal-plastic crowns are one of the most economical types of prosthetics. Inexpensive types of metals (nickel, chromium, cobalt) and their alloys are used as a metal base. This option is suitable for temporary prosthetics. The crown can last 2-3 years. Dentures are fragile, can cause irritation and allergic reactions, and the material darkens over time.

pros

Low cost.

Minuses

Fragility;
may cause irritation and allergic reactions.

Stages of dental prosthetics

The total duration of the procedure for restoring teeth using metal-ceramic prosthetics is approximately 1-2 weeks, in some complex cases it may take a little longer due to the individual characteristics of the patient’s treatment plan. The preliminary part is the therapeutic part, during which it is necessary to heal all teeth with caries, gum disease, and perform root canal filling. After this, you can begin installing the prostheses. The process includes the following steps:

Consultation and development of a treatment plan for the patient.
Tooth preparation for metal ceramics. Using painkillers, the tooth is ground down. A metal-ceramic crown can be installed on a living tooth, but there is a need to depulp it. Choosing a method of fixing a crown on a pin or inlay, in the absence of most of the tooth.
Taking impressions of the lower and upper jaws.
Making a prosthesis by a dental technician using individual impressions. It includes two stages: manufacturing a metal frame and applying layers of ceramics to it.
Trying on a prosthesis.
Fixation of the prosthesis to the patient.

Cost of installing metal ceramics

The cost of installing a metal-ceramic prosthesis by several factors, the main ones being preparation of the tooth for prosthetics and whether the tooth needs to be depulped. How will the crown be fixed to the tooth using a pin or inlay? The fundamental factor is the complexity of each individual clinical case. The cost of a metal-ceramic crown in our clinic is 7,000 rubles. for one unit .

It is possible to determine the final cost and draw up an individual treatment and prosthetic plan during a personal consultation with an orthopedic dentist.
