Features of the manufacture and installation of gold crowns

The use of gold for dental prosthetics has a long history. Gold has not lost its relevance in dental practice.

New technologies offer the use of various strong and composite materials. Noble metal has excellent performance.

Modern gold products are different from traditional crowns, primarily a complex design. Gold for crowns is a complex alloy of several metals. Dentists use gold of such samples:

• 916 test( gold - 91.6%, silver - 4.2%, copper - 4.2%);
• 900 sample( gold - 90.0%, silver - 4.0%, copper - 6%);
• 750 sample( gold - 75.0%, silver - 8.3%, copper - 16.7%);
• 583 test( gold - 58.3%, silver - 13.7%, copper - 28.0%).

It should be noted that jewelry and dental gold are different in composition.

The most popular products in the restoration of the dentition are crowns using, in addition to the gold alloy and other noble metals - platinum, palladium.

Such products are closed with metal-ceramic composites. Manufactured by such technology, crowns are the most suitable for natural color. The golden base gives the product a natural warm shade. In this case, the transition to the color shades of the prosthesis to the neck of the tooth from the incisal edge is as close as possible to natural color.

It is desirable to install products from solid gold on molars of the chewing group, and on the front teeth it is better to choose another material. They are not visible, they do not spoil the appearance of a smile.

Features and composition of gold crowns

Fromalloy 916-th sample make crowns, inserts, bridges. This alloy does not lend itself to corrosion processes, it is easy to process, has a small shrinkage, and therefore the products made of it are highly accurate. The alloy is characterized by a high hardness which leads to rapid abrasion along the line of closing of the prosthesis.

For the same products, the alloy of the 900th test is also used. Compared with the 916-th test, it is even harder, similar in performance.

From the alloy of the 750th test, parts and elements of prostheses of removable structures are made-hooks, clasps, etc.

The use of less copper in alloys due to cadmium( up to 10.0%) leads to a significant decrease in the melting temperature. Such an alloy is used as a solder when connecting different prosthetic parts from the more expensive samples of the 900th and 916th.

Of the 583-th test, pins and some other elements are made. Such products have anticorrosive characteristics lowered.

Indications and contraindications

The installation of crowns has not so many individual indications. If the patient has an increased abrasion of the enamel, then to eliminate this pathology, it is necessary to fix the level of teeth clamping with the help of metal( gold) crowns.

The variant of the crowns made of gold is the most optimal due to good survival in the body. It is possible to replace gold products with other modern materials - cermets, ceramics. They are virtually identical in color to natural teeth, provide a long and comfortable operation, do not damage the gums and adjacent teeth.

Gold products are relatively expensive, do not meet modern aesthetic requirements, the material is harsh.

To put gold crowns on teeth it is possible also and at will of the patient. The trend is gaining increasing popularity among celebrities in the West.

Here are the main indications for prosthetics with gold alloys:

• recovery of chewing and speaking functions of jaws;
• giving the broken tooth an original anatomical shape;
• strong bite correction;
• elimination of problems( gnashing of teeth in a dream, jaws strongly squeezed, etc.);
• fixation of weak teeth;
• restoration of aesthetic dentition;
• complete restoration of chewing molars;
• if there is an allergy to other dental prosthetics.

It is not advisable to make prosthetics with gold alloys in such cases:

• in the presence of problems with mental health rights;
• periodontal disease of the oral cavity;
• course of pregnancy;
• to persons under 16 years of age.

If the desire to be replaced with gold has not disappeared, it is desirable to eliminate contraindications. In cases of impossibility of such prosthetics, experienced dentists will select and recommend the most appropriate option for restoration and correction of teeth.

Types of gold crowns

Dentists use gold not in pure form, but in the composition of alloys. Because the metal is too soft. In the composition of the crowns, add other precious metals - palladium, platinum. Dental products can be covered with other composite materials - ceramics, cermets.

The application of a decorative layer on the outside of the product is fraught with the formation of chips. For reliability, the product as a base is covered with a layer of composite aesthetic materials. This technology is complex and expensive.

Depending on the technology of making the crowns of gold alloys, there are such types:

1. Stamped .At the present stage of development of prosthetics, this technology is giving up its positions. The products are made of gold alloy plates or sleeves. The technique requires the completion of the workpiece, the crown does not always sit tightly on the body of the tooth, there may be gaps and rubbing the gums.
2. Solid-cast .The technology makes it possible to make an exact copy of the tooth shape. Such products fit tightly and do not damage the gums. They serve longer stamping. Requires preparation of the tooth for installation( grinding, etc.).

Procedure for the manufacture and installation of

To install the crowns, the following manipulations should be performed:

• to prepare the oral cavity( sanation, treatment, removal of nerves, etc.);
• Impression of both jaws;
• manufacturing of models from gypsum on the basis of received impressions;
• manufacturing of wax copies of the crown;
• fitting the wax cast;
• product casting;
• fitting, grinding and final fixation in the oral cavity.

Advantages and disadvantages of

The undeniable advantages of using gold alloys in prosthetics are such factors:

• versatility of use( can be used in various prosthetic options);
• gold is a neutral material, does not oxidize, does not affect the taste of food;
• practically allergenic reactions are absent, the metal is close to enamel by properties, biocompatible with the tissues of the body;
• excellent hygienic indicators( no unpleasant odor from the mouth, does not cause inflammation);
• is quite strong material and is capable of withstanding significant loads;
• thanks to good plasticity of gold, the product well follows the shape of the tooth, snugly;
• gold crowns with normal care can be used for more than two decades;
• good compatibility with other materials, does not cause galvanic currents;
• released gold ions have an anti-inflammatory effect when ingested with saliva in the human stomach.

Prostheses made of gold alloys have a number of disadvantages, namely:

• pleasure is not cheap from the patient;
• the treated tooth is deprived of protective enamel and part of a solid body;
• does not have high aesthetic characteristics in the light of current trends towards naturalness.

Recovery period and special recommendations

After the installation of the gold crowns, the patient undergoes a certain period of adaptation. On the recommendation of the dentist during the first month should refrain from eating solid foods. Patients after prosthetics may encounter such conditions:

• initial hypersensitivity, usually occurs after the end of the action of anesthetics;
• biting process causes painful sensations - it is necessary to adjust the fitting of the prosthesis;
• in rare cases of bruxism the patient is prescribed the use of nocturnal drops;
• , when a cement smell appears in your mouth, you should contact the dentist again to fix the problem( prosthesis removal, correction and cementing anew);
• with the appearance of discomfort for hot and cold products, the dentist ascribes special pastes, but it is better to remove and eliminate the problem of poor-quality depulularization of the tooth.

Care for gold teeth

Special recommendations for the care of gold teeth will not be needed. As always, you should brush your teeth in the morning, in the evening, use mouth rinsers, visit the dentist's office every six months. The service life with proper care can exceed several tens of years. In some cases, they need to be removed, namely:

• inflammation in the oral cavity;
• violation of integrity( crack, wear, mechanical damage);
• preparation of the oral cavity( sanation) was carried out at a low level and as a consequence inflammation under the crowns;
• replacement by expiry date.

Gold crowns can be removed either by sawing or by gentle methods for re-use after the elimination of dental complications.

Alternative prosthesis options

There are alternative methods of prosthetics:

• ceramic prostheses, plus - aesthetics, cons - expensive and not very strong;
• all-metal prosthesis, pluses - the cost is available, cons - not very nice and the likelihood of allergies;
• use of zirconium dioxide, pluses - excellent aesthetics, strength, minuses - high cost is more expensive than gold.

The cost of

The material is expensive, so inserting gold crowns on the tooth can cost differently. The price depends on several factors:

• product weight;
• gold sample;
• manufacturing method;
• qualification of dentist-orthopedist and technician;
• level of the clinic.

Prices for gold teeth( types of products) can range from 5000 to 40000 rubles per unit.

The use of gold in dentistry is proven by time, has undeniable advantages. The patient receives qualitative prostheses without harmful influences on an organism. The aesthetic side suffers a little, but the advantages cover up the shortcomings.

The use of gold as a basis for prostheses, crowns and other composite materials makes prosthetics a worthwhile investment in your health for a long time.
