Dental gold: what standard of gold is used in dentistry, indications and contraindications for use, procedure for installing crowns

Gold is a universal metal. It is used not only in jewelry, but also in medicine. Among the main areas of application: dentistry (so-called dental gold), as well as homeopathy (solutions with colloidal gold).

This process is possible because:

• Gold is a noble metal. This means that it does not react with surrounding substances under normal conditions. It does not turn black over time and does not form films. Therefore, the composition of saliva and other human juices will not be able to change the properties of the metal and its characteristics.
• The metal is hypoallergenic, and very rarely there are adverse reactions to it. In prostheses, the substance is well accepted by the body and the implant quickly takes root.

Why is gold used in dentistry? Dental crowns - what are they?

Gold has been used by dentists for centuries. Previously, teeth made of precious metal were an indicator of luxury, available only to those in elite circles. Today, such material is used due to its inertness and strength, even despite its high cost. Dental gold is especially relevant in cases where it is impossible to use another material for prosthetics for medical reasons.

Most often, precious metal is used to make crowns, which are a kind of cap for damaged teeth. Dentists use a special alloy to restore single chewing teeth that are subjected to heavy loads or to restore an entire row of teeth.

The use of gold for prosthetics is due to the safety of the metal for the human body. The material is not capable of causing allergic reactions, oxidizing or reacting with food.

Gold in dentistry can be used to make:

• half-crown;
• gold-platinum stump inlays;
• equatorial crowns;
• metal-ceramic gold crowns;
• metal-ceramic gold crowns for implants;
• metal-ceramic crowns on galvanic gold.

Where to sell the 850

Dental samples are accepted at pawn shops. They buy crowns at a reduced price as scrap precious metals. Pawn shops apply deductions for dirt. Before being sold to a pawn shop, crowns are cleaned of plaque and dental material. It is recommended to call pawn shops in advance to find out the conditions for accepting crowns.

Pawn shops do not accept gold-plated teeth coated with gold.

The purchase of the eight hundred and fiftieth is carried out by illegal buyers. The purchase price will be as low as possible. Gold crowns are accepted by jewelry workshops for melting down and further use.

High standard dental gold

The question has always arisen, what grade of dental gold is used by dentists. The answer is quite simple; in dentistry, an alloy from 916 to 585 can be used, depending on the type of parts:

• 916 - inlays, facets, bridges, crowns, half-crowns;
• 750 — pins, springs, inlays, half-crowns;
• 585 – clasps (hooks for fixing removable dentures).

Table: average cost of dental crowns

It is important to remember that the cost of prosthetics is influenced by the price of a gram of precious metal and the materials used, the method of manufacturing the structures, the status of the clinic and the specialists who make dentures. Because of this, prices in different dentists and regions can vary significantly.

Why a gold crown is a good investment

Some houses still have old gold teeth. If you consider what grade of gold dental crowns are made from, they can be profitably sold to companies that are interested in buying such items. Today there are such companies in Moscow, Volgograd, Kostroma, Ufa and other regions of the country. That is why dental gold is often a highly liquid metal that can easily be converted into money.

Why you shouldn't pawn crowns at a pawnshop

To make dental gold, 900 or 916 samples are used, but you should take it to a pawnshop only in case of a hopeless situation. Such material is considered a semi-finished product and, as a rule, its price is low.

It is important to remember that installing one such tooth is expensive for clients, the cost starts from 11 thousand rubles. However, a pawnshop will value such a product at only a few thousand. This means that the owner of the teeth will lose significantly during such a sale.

It is also important that individual specialists can replace part of the precious metal with other less expensive metals and do gold plating.

Patient reviews

And I like gold teeth. This has always been considered an indicator of financial importance. I still have dentures from my grandmother; I can take them to a pawnshop. You just need to find out how to clean gold crowns from your teeth and check what kind of gold dental crowns are made of. But I wouldn’t put one on myself, because it’s unfashionable now.

Sergey, St. Petersburg

I am against gold teeth. They look unnatural. But last year I knocked out my front tooth during training. I went to the dental clinic and, as it turned out, not all dentures suit me. The dentist recommended inserting a gold tooth. I doubted it very much, but there were no other options for me. It turns out that they are placed for medical reasons. Especially if there are problems with the kidneys or liver.

In addition, gold dentures last about 15 years. You just need to take proper care of them. I asked what type of dental crowns are used. The doctor explained that gold teeth are of high standard and joked that this is a good investment.

Maxim, Nizhny Novgorod

Several years ago, on the recommendation of a doctor, I had gold teeth installed. It’s good that they are not front, so they don’t interfere with the aesthetics of the look. Gold interacts well with gums and does not cause discoloration. I didn't have any allergic reaction. I know that such teeth do not cause any negative reaction in the body. They are placed if the patient has significant stomach problems. Coated teeth often cause various complications.

However, I think that from time to time it is necessary to take pictures to make sure that everything is in order with the teeth.
It's just for insurance. And so they will serve for at least 10 years, or even more. Marina, Orel

Indications for the installation of gold crowns

• it is necessary to accurately restore the shape of the teeth;
• the need to restore chewing teeth that are subject to heavy loads;
• the patient has a strong bite or has a habit of grinding his teeth or clenching his jaw tightly;
• the need to strengthen dental tissues;
• the need to improve the appearance of the dentition.

The benefits of crowns in the mouth

Using a gold crown is beneficial for the following reasons:

• the metal does not allow chewing teeth subject to constant stress to deteriorate;
• gold helps restore already destroyed tissues;
• often allows you to replace a natural tooth;
• helps hide imperfections in natural teeth that have irreversibly changed color.

Clasp dentures made of gold.

A 750 alloy alloy with the addition of platinum is used. Increased hygiene and high aesthetic properties. A small drawback is the high price; it is precisely because of such designs that there are ridiculous rumors about rich dentists.

Gold alloys for dentistry

• 916 gold alloy is used for crowns and bridges. The inside of the crowns is reinforced with a layer of 750 gold.
• 750 gold alloy. For the manufacture of clasp dentures, clasps, the alloy is more elastic and durable.
• Super TZ alloy has higher hardness.
• Superpal. This alloy is 90% palladium, but has the color and properties of gold.
• Imported casting alloys for metal-ceramic prostheses V-classic (Switzerland), Stabilor-G (Germany).

There are other alloys of noble metals, but in this area it is advisable to be a little conservative and use a time-tested material that has proven itself well.

Prices and payment features

Gold-containing alloys are purchased by dental laboratories and dental technicians from their suppliers and receive appropriate certificates and documents confirming the quality of the products.

Contraindications for installing crowns

• the patient is under 16 years of age;
• increased dental mobility was diagnosed;
• the presence of chronic periodontitis;
• the patient has mental illnesses;
• pregnancy.

How does the installation work?

The installation of gold crowns can be generally described as follows:

• on a previously prepared tooth (ground to 0.5-1 mm, depulped), a prosthesis obtained from the laboratory is tried on, if necessary, it is adjusted,
• check the density of shrinkage and the correct closure of the teeth, while the patient should not feel discomfort,
• fix the product with dental cement.

You need to remember that you cannot get a gold crown in the first clinic you come across. To manufacture and install such products, a medical institution and laboratory must have a license. In addition, the specialist must have at least 5 years of work experience in this field.

Advantages and disadvantages of gold teeth

Gold prostheses have the following advantages:

gold is not capable of harming teeth and, on the contrary, has a positive effect on the oral cavity and the entire body;

the inertness of the metal does not allow it to react with saliva or food;

when closing the jaw, the golden tooth is not capable of destroying tissue in opposite rows;

the precious metal is not capable of causing the development of allergies;

gold alloy is a strong, durable material.

The use of gold crowns also has its disadvantages:

the use of almost pure gold implies its natural softness. Although the alloy contains a ligature that enhances its strength, such teeth will gradually begin to wear out, although decades may pass;

the high cost of the source material is not accessible to everyone;

gold dentures look good on the sides; to restore the front teeth, it is better to choose a different material.

How to care? How long will such a tooth last?

With proper care, such crowns will last a very long time - up to 15 years. For some people, gold teeth last 20 or 30 years and look great. To keep them in excellent shape, no special effort is needed. You just need to clean them twice a day as usual. You can rinse with antibacterial solutions or plain water. Visit your dentist's office every six months to evaluate the condition of your dentures. Dental gold dentures are the best and long-lasting solution for your teeth that do not require extensive maintenance.

New trend for a golden smile

The fashion for gold teeth has been around for a long time. They are actively used in modern prosthetics. At the same time, flashing a golden smile with different inserts is now at the peak of popularity. For this purpose, grills are used - precious jewelry that can be worn on one or more front teeth.

Fashionable jewelry for teeth - gold grills
This accessory is not tightly fixed and can be easily removed if necessary. They can have absolutely any shape, be inlaid with stones, and made from various materials. You can buy jewelry in Russia via the Internet with delivery to Podolsk, St. Petersburg, Krasnoyarsk, Togliatti, Chelyabinsk, Samara and other cities of the country. You can also find a specialist who can make custom-made grills.

Don't let yourself be deceived by a scammer

The most pressing topic, which all experts mostly refuse to talk about, is fraud on the part of jewelers. Of course, the lion's share of goldsmiths work honestly. But only a few of them speak publicly on this issue and give clients advice on how to protect themselves from dishonest colleagues or outright scammers.

When contacting unverified authors, people may encounter these types of scams.

1. Substitution of precious stones.
2. Dilution of gold composition.
3. Conscious increase in the consumption of precious metals in the manufacture of jewelry.

Few people turn to private jewelers to melt down their gold, and therefore word of mouth does not work well in these cases. Not each of us has such acquaintances whose opinion we could safely rely on. Therefore, you will have to contact jewelers at your own peril and risk, testing their honesty experimentally.

To insure yourself against fraud, you need to be extremely careful and require various additional checks. For example, if you brought a gold item to a jeweler inlaid with stones that you want to see in a new piece of jewelry, ask that you record all their characteristics. Carefully inspect the stone yourself and note that there are no chips or scratches on it. If the pebbles are small and there are a lot of them, carefully count the number. When receiving a new gold item, double-check everything carefully.

Why did the crown sag after a few years?

The human body is characterized by age-related changes, which include a decrease in the volume of gum tissue. In this case, the upper row of teeth rises, and the lower row falls accordingly. Dentists call this process recession. This means that if there are crowns, a gap may appear between the gum and the “cap”, caused by tissue movement. In case of discomfort, you should consult your doctor.

Why does the crown cause a sour taste in the mouth?

Expert opinion

Kibantseva Elena Anatolyevna

Allergist-immunologist, “Movement” clinic, Saratov

A sour taste in the mouth may be a sign of galvanism in the mouth. That is, if there are crowns made of different metals, electrical impulses may appear between them. As a result of such chemical reactions, the patient begins to feel a sour metallic taste. If you ignore such symptoms in the future, you may encounter serious problems not only in the oral cavity, but also in the entire body.

Which crowns have better properties: gold or expensive metal-ceramics?

Expert opinion

Pribrezhny Gennady Valentinovich

Jeweler 6th category

Each type of crown has its own composition and properties. They have their pros and cons, and also differ in cost. The use of precious crowns is due to the following characteristics:

• durability, lasts at least 15 years;
• comfortable to wear;
• minimal impact on natural teeth;
• corrosion protection;
• increased strength.

However, their main disadvantage is the unnatural color of the coating.
That is why such structures are not used for prosthetics of anterior teeth. The advantages of metal ceramics are:

• durability, lasts at least 8 years;
• natural appearance;
• partly consists of precious metal.

At the same time, cracks and chips sometimes appear on such prostheses, which appear due to poor quality materials or improper installation. They are less durable, but can also withstand chewing loads.

How are they made?

Gold crowns are solid structures. They are installed on the ground base of the tooth after the dentist has prepared the mouth. Afterwards, models are sculpted using plaster. They will become an exact copy of your future crown for the technician. The doctor takes into account all physiological characteristics and makes a suitable prosthesis. Following the plaster blanks, wax copies are made. They are needed so that the dentist can compare them with photographs and try them on in the patient’s oral cavity. The wax blanks can be adjusted, and then the dentist sends them to cast gold crowns. Before installing them in place, the dentures are ground and polished.

Gold alloys

If we consider this precious metal in a completely pure form (or very close to pure - without impurities), then it is a soft and malleable metal. gold alloys are widely used

with other metals. The most common alloys are copper and silver, less often - with platinum and palladium, and even less often - with steel and cadmium.

Gold alloys

with antimony, lead, bismuth, tin and zinc are not used for jewelry, since they are very fragile and therefore cannot be processed by impact or in rollers. Provided it is alloyed with silver and copper, it can be rolled and forged well. With this treatment, the alloy becomes very hard, which in turn requires calcination.

Alloys with steel, platinum and palladium are rarely used. This is explained by their high hardness and refractoriness, which makes such alloys difficult to process. Alloys with cadmium are quite fusible, but due to their fragility they are rarely used.

The presence of metals in a gold alloy is called ligature

.

Gold content

Gold content

determines the quality of the alloy and the weight content of pure metal for every thousandth part of the alloy. If they say that gold is 583 standard, then every thousand parts of the alloy consists of 583 parts of pure metal and 417 parts of alloy, that is (583+417=1000).

Gold content

also determined using a touchstone with a polished matte surface. The product is passed over it and the trace left is compared with the color of the strokes from standard metal alloys of a known standard.

To approximately determine the sample, a chemical method is also used: the mark on the touchstone is treated with special solutions. Concentrated 72% nitric acid completely dissolves traces of gold alloys less than 333 fine. If the streak turns brown, the sample corresponds - from 333 to 500, and if there were no changes - above 500. The brown trace is finely crushed gold remaining after the dissolution of other metals (copper, silver) in the alloy. Using a mixture of nitric and hydrochloric acids, you can establish in a few minutes the approximate content of precious metal in alloys with a fineness of 160 to 1000.
