IMPORTANT!

If you are planning to install dental implants, you need to find out in advance whether they will take root with you.

______________________________________________________________________

The installation of dental implants is associated with large financial costs for the patient, which is why it is necessary to know in advance that allergies to implants will not occur.

According to European statistics, 26% of the population has a genetic intolerance to titanium , from which dental implants are made.

Irritation due to galvanic syndrome

Galvanic syndrome is a condition when an electrical impulse occurs between prostheses made of dissimilar metals. Moreover, crowns can be metal, metal-ceramic, or metal-plastic (the main thing is that metal is present). Galvanism occurs not only between crowns, but also between crowns and other prostheses. For example, clasp with metal hooks or a palatal bridge, as well as implants (less often). There is a tingling sensation in the mouth, an “electric sensation,” and a sour or bitter taste.

The occurrence of galvanism depends on how dissimilar metals are able to interact with each other (how different their electrochemical activity is), and not on the quality of the metals themselves. Therefore, you should always be interested in what crowns are made of and report this important information to the dentist during subsequent prosthetics. According to statistics, 15-35% of orthopedic dentists’ patients experience galvanic syndrome. For example, galvanosis may appear due to the presence of gold and nickel-chrome prostheses.

Get laboratory diagnostics for titanium intolerance in Germany:

• if you want to insure yourself against implant rejection
• if you want to know that you are not paying for implantation in vain
• if you want to correctly and individually select the material for dental implants

Implantologists at German and Swiss VIP implantology clinics recommend diagnosing titanium tolerance in 100% of patients, thereby insuring themselves and their patients from severe complications after the installation of dental implants and rejection of dental implants.

There are 2 types of studies that predict implant failure:

1. Type of determination of intolerance to titanium implants (Titanium intolerance TEST)

This study is recommended for all patients before installing even 1 dental implant.

The cost of Titanium intolerance TEST is 19,800 rubles 00 kopecks.

The analysis is carried out directly in a laboratory in Germany.

The price includes blood collection and transportation of blood samples to Germany.

1. The type of study includes determination of intolerance to titanium implants (Titanium intolerance TEST) and determination of genetic polymorphism of interleukins (Degree of inflammation IL-1, IL-1RN, TNF-alpha-genotype).

This study is recommended for patients to undergo before installing 4 or more dental implants and especially when installing zygomatic implants. This test, with a positive conclusion, indicates not only the possibility of early implant rejection, but also indicates late implant rejection.

Cost Titanium intolerance TEST + Degree of inflammation TEST

38,800 rubles 00 kopecks.

The analysis is carried out directly in a laboratory in Germany.

The price includes blood collection and transportation of blood samples to Germany.

_______________________________________________________________________

This cost is tens of times less than the cost of implants and prosthetics in Moscow. For example, the average cost of the popular Nobel Biocare implant, gum former, abutment and zirconium dioxide crown in Moscow is 130,000 rubles turnkey. What if 3-12 such implants are installed?

Diagnostic measures

Timely assistance from a specialist will help prevent the worsening of the condition and the development of complications. Initially, the doctor will perform bimanual palpation and determine the need for subsequent laboratory and instrumental diagnostic methods.

Making a diagnosis may require:

• orthopantograms (dental x-rays);
• tests and samples in the laboratory (Müllemann test, Schiller-Pisarev test);
• computed tomography;
• examination of biomaterial from the affected area (determination of the type of pathogenic microflora).

The specialist also performs a differentiated analysis of signs to exclude pathologies with similar symptoms: cystic suppuration, mucositis, periostitis.

TITANIUM INTOLERANCE - TITANIUM INTOLERANCE. ALLERGY TO TITANIUM.

Titanium has outstanding properties, which means that, compared to other metals, it is well tolerated immunologically.

However, it is known that in 26% of patients, implants cause adverse signs of inflammation, which lead to:

- lack of bone integration of implants,

- failure to engraft a dental implant,

— rejection of dental implants in the first 6 weeks after implantation

— rejection of dental implants within one to five years after installation

- peri-implantitis.

True cellular allergies of type IV to titanium are rare compared to other metals. The reason is that titanium ions have a high affinity for oxygen and therefore form oxides immediately after their release, and unlike free ions, these oxides cannot form protein bonds and therefore allergic effects cannot develop.

The often heard statement that “there is no allergy to titanium” is quite likely true from an immunological point of view. However, allergies are not the only cause of immunologically related intolerance. The most common cause of individual hypersensitivity to titanium is excessive proinflammatory reactivity of tissue macrophages. Macrophages are special cells of the body that are responsible for protecting humans from foreign substances and bacteria.

Titanium particles in the tissue cause an inflammatory response, which leads to implant rejection.

Studies have shown that titanium particles are always found in the bone and soft tissues surrounding the implant. Tissue macrophages ("scavenger cells") phagocytose (ingest) these titanium oxide particles (particulate matter). As a result, a physiological response of the patient's tissues to the implantation occurs, such that macrophages react to contact with titanium oxide particles by releasing pro-inflammatory cytokines, in particular TNF-α and interleukin-1.

However, the extent of this immune response is very individual.

The intensity of cytokine release depends on the genetic variants (polymorphisms) of the proinflammatory (IL-1 and TNF-α) and anti-inflammatory (IL-1RN) mediators involved.

Therefore, titanium intolerance usually results from an increased propensity of tissue macrophages to become inflammatory in response to titanium oxide particles. Titanium-specific lymphocytes do not play a role here, which explains the negative results of LTT and the results of the skin test.

To what components of structures can an acute reaction of the body occur?

The above symptoms occur when the body does not “read” certain substances contained in the structures as homogeneous to it. Since they are made from artificial materials, some elements contained in the material or unwanted chemical reactions that occur under the influence of certain conditions can cause allergies. The following materials/components can act as an allergen and cause an inflammatory reaction:

• various metals in the composition: the use of cobalt, chromium, nickel and their combinations in production somewhat reduces the cost of construction, which makes them popular. They are used to create budget crowns and bridges made of metal-ceramics, as well as the basis for removable clasp dentures. The presence of these metals in dentures becomes a common problem for allergy sufferers due to spontaneous corrosion processes - destruction of the metal. It occurs under the influence of the chemical components of saliva, due to the “hostile” interaction between different metals in one prosthesis. Temperature changes during the manufacture of structures also have an impact, causing instability of the material,
• toxic elements such as copper and manganese. Under the influence of electrochemical processes in the oral cavity, these metals are released from the supporting material and enter the blood, saliva, and gastric juice. Thus, they increase the undesirable concentration of antigens and provoke allergies,
• dyes in dentures can also trigger an immune response. They are used to provide aesthetics, but are not always biocompatible,
• Some types of plastics (most often inexpensive acrylic) can provoke stomatitis or, again, acute allergies. The residual monomer must be contained in the prosthesis in a certain concentration - no more than 0.2%. Exceeding this proportion in case of violation of production technology causes an inflammatory process in the mouth,
• galvanic currents that arise due to the heterogeneity of metals incompatible with each other and have an irritating effect on tissue. Different metals can act as electrodes in relation to each other, saliva serves as an electrolyte, and the entire system produces microcurrents. The so-called “galvanic syndrome”, or galvanism, is manifested by a number of symptoms, such as a metallic taste in the mouth, increased salivation, sleep disturbance, distortion of the sense of taste, and more.

Interestingly, acrylic, which is used in orthopedics, is a high-polymer compound of a non-protein nature. Namely, it is to foreign proteins that allergies mainly occur. But the monomer contained in acrylic, which is called methacrylic acid methyl ester, can combine with body proteins as a potential hapten and turn into an antigen.

Modern prosthetics have developed several new composites that are more biocompatible. New technologies are being used in this area. Now designs made of safe plastics have come into use, for example, soft and durable nylon. Allergies to nylon dentures are extremely rare. Ceramics, from which a large proportion of structures are made, are also safe for the body. It is reliably known that metals such as gold, silver, titanium, and iron are resistant to corrosion and do not cause allergic reactions. But the tolerance of the components is individual for everyone, so it is impossible to say with one hundred percent certainty that the prosthesis will not cause rejection.

ALLERGY TO TITANIUM. ALLERGY TO IMPLANTS.

Risk of titanium dental implant loss in healthy patients with titanium intolerance:

THE FOLLOWING VALUES SHOULD BE CONSIDERED AS THE CRITERIA FOR THE TEST FOR INTOLERANCE OF DENTAL IMPLANTS:

Titanium intolerance TEST

negative titanium stimulation test there is no risk of rejection positive titanium stimulation test the risk of rejection is 12 times greater

Degree of inflammation IL-1, IL-1RN, TNF-alpha-genotype

genetic degree of inflammation 0 risk of rejection no genetic degree of inflammation 1 risk of rejection 1.5 times greater genetic degree of inflammation 2 risk of rejection 2.4 times greater genetic degree of inflammation 3 risk of rejection 3.8 times greater genetic degree of inflammation 4 risk of rejection greater 6 times

Comment: A patient with a positive titanium stimulation test has a 12-fold increased risk compared to the normal population.

If he or she also has a genetic grade 4 inflammation, the risk increases sixfold, IN THIS CASE TITANIUM IMPLANTS CANNOT BE INSTALLED.

What does a positive titanium stimulation test or increased genetic inflammation mean?

A positive test result (titanium intolerance) in one of the two tests indicates the presence of a significant predisposition to the development of titanium-related inflammation, which may be associated with primary or secondary implant loss.

This is not the same as an allergy, which requires that the allergen be avoided as a matter of course.

Therefore, a positive titanium stimulation test or inflammation grade of 2 to 4 is not an absolute contraindication for a titanium implant.

However, in these cases, alternatives (eg, ceramic implants, removable bridges, coated titanium implants) should be critically evaluated and preventive measures should be increased (prophylaxis, use of reduced rotation speeds, avoidance of titanium periodontal probes, immediate implants, removal of sources of infection, smoking cessation , optimal correction of other predisposing diseases (diabetes mellitus), absence of multiple implants, avoidance of immunostimulation for up to 4 weeks after implantation).

Should an implant allergy test be performed before implantation or in cases of suspected titanium intolerance?

An allergic reaction to titanium, as mentioned earlier, is extremely rare, due to titanium's strong tendency to oxidize. Thus, LTT is much less important for dental problems compared to the titanium stimulation test.

However, even dental implants from the most famous manufacturers contain elements such as nickel, vanadium and aluminum.

These metals are super allergens.

From the point of view of type IV sensitization, metal contaminants are of greater importance in the development of implant rejection.

For this reason, an LTT screening profile in addition to the titanium stimulation test has been developed, in which these three metals are tested in addition to titanium.

By undergoing laboratory diagnostics in our clinic for intolerance to titanium implants , you will protect yourself from severe complications associated with implant rejection and save your money.

Preventive measures after installation of an implant or prosthesis

Implants must be installed after a thorough examination of the medical history, the absence of contraindications and allergy tests. Then there will be no exacerbation of the allergic reaction. After implantation, you must adhere to the following rules:

• avoid stress;
• rinse your mouth after eating;
• Healthy food;
• reduce the consumption of spicy, sour foods;
• exclude strawberries, citrus fruits, coffee, eggs from the diet;
• quit smoking.

Even ordinary mineral water provokes allergies because it accelerates electrochemical processes in the oral cavity.

SURVIVAL OF IMPLANTS.

The survival rate of implants depends on several factors:

• tolerance to titanium and lack of macrophage polymorphism.
• absence of allergies to impurities: nickel, vanadium and aluminum.
• compliance with the technique of installing a dental implant.
• absence of bone burn during implantation.
• compliance with the rules of septicism and asepsis in the clinic during implantation.
• correct choice of thickness and length of the implant.

If points 3, 4, 5, 6 depend only on the qualifications of your implantologist, then points 1 and 2 from this list depend on genetic changes in the patient’s body. This is why it is necessary to conduct laboratory diagnostics of implant survival before implantation.

IMPLANT REJECTION. REJECTION OF DENTAL IMPLANT.

Implant rejection is the lack of growth of bone tissue to the surface of a dental implant, or the destruction of this connection, which was formed earlier.

An inflammatory process begins in the bone tissue, which leads to implant rejection and peri-implantitis.

Implant rejection is classified:

• implant rejection in the early stages, up to 4 weeks after implantation.
• implant rejection in the later stages, after 6 months after implantation.

Implant rejection is a serious treatment complication that must be prevented!

Plastics and acrylic are the most allergenic materials

According to research, synthetic polymers - plastic, polyurethane, nylon, acrylic - provoke an allergic reaction in approximately 1% of cases, i.e. in 1 in 100 people. In principle, this is not little, but not very much either. As a rule, plastic crowns are often placed only on a temporary basis - so that the patient does not go without a tooth while more durable permanent ones are made. So a large concentration of potential allergens should not have time to accumulate in the tissues. But still, slight irritation of the gums or allergic stomatitis can appear in people with high sensitivity and a weakened body.

If we consider the acrylic from which artificial gums are made (it is sometimes built up around bridge crowns if the gum contour is not very smooth), then the allergen here is the acrylic monomer. But today there are materials with low monomer content or without it at all - for example, Acry-free.

SYMPTOMS OF IMPLANT REJECTION. SIGNS OF IMPLANT REJECTION.

Signs of implant rejection may be completely absent. Sometimes the patient does not notice any symptoms of implant rejection. Only when the dentist begins to check whether the implant has grown to the bone tissue or not, he discovers that the implant is not fixed to the bone.

However, most often the patient experiences the following symptoms of implant rejection:

• redness of the mucous membrane in the area where the implant is installed.
• change in color of the mucous membrane in the area of ​​implant installation to bluish.
• discharge of pus from the gums in the area of ​​implantation.
• pain when pressing on the gums in the area of ​​implantation.
• proliferation of granulation tissue in the area of ​​implantation.
• not a significant increase in body temperature.
• mild pain in the implantation area.
• loosening and mobility of the implant.
• a change in a clinical blood test indicating inflammation in the body.
• acceleration of ESR in clinical blood tests.

If these symptoms of implant rejection are detected, it must be urgently removed.

How is the disease diagnosed?

To diagnose the disease, you may need to consult an allergist, immunologist, or dermatologist. Diagnostics is accompanied by the following stages:

1. Sanitation of the oral cavity . The doctor will note the moisture content of the mucous membrane, its condition, the type of saliva, and the presence of defects. Receive information about the composition of the implant and time of use. Oxide films indicate the development of allergic reactions.
2. Allergy tests . They are prescribed to identify allergens. There are several types: cutaneous and provocative. The first type of test involves introducing a drop of allergens into skin incisions. Provocative tests are done only in a hospital, when other diagnostic methods turned out to be uninformative.
3. Elimination and exposure test . Used in the presence of removable dentures. Elimination - removal of the prosthesis for a period of one day to 7 days, until allergic symptoms disappear. Exposure - installation of a prosthesis after the disappearance of negative manifestations.
4. Isolation of the prosthesis from the mucous membrane. It is performed by fixing gold foil to dental glue and cement. Used for fixed dentures.
5. Analysis of venous blood for antibodies responsible for the occurrence of an allergic reaction.

CONSEQUENCES OF IMPLANT REJECTION

If a dental implant fails, it must be removed immediately. After removal of the implant, bone grafting is necessary. After removing the implant, you must wait 4 months and reinstall the implant.

If you do not remove the rejected implant, serious complications will arise:

• destruction of bone tissue in the area of ​​the rejected implant.
• periostitis.
• osteomyelitis of the jaw.
• sepsis (blood poisoning).
• abscess.
• phlegmon.

Treatment methods

Allergies cannot be cured. Symptoms of an allergic reaction can be relieved. There are two ways to solve the problem of allergies to fixed structures . The doctor can:

1. Remove the implants and install structures that do not cause allergies. The method requires identification of the allergenic component. A new structure can be installed no earlier than a month after the first one is removed.
2. Metallize the surface of the implant with hypoallergenic materials. Usually gold and platinum are used.

Drug therapy is not always required. Initial symptoms following surgery usually go away on their own. If this does not happen, the following may be prescribed:

• Antihistamines (Loratadine, Fenistil, Zodak, Claritin).
• Antiallergic - antihistamine (Fenkarol, Diphenhydramine, Tavegil).
• Adsorbents (Smecta, Polysorb).
• Hormones.
• Ointments for the oral cavity (Cholisal, Metrogyl Denta, Vokara).

Additionally carried out:

• plasmapheresis - filtration of blood plasma through special membranes;
• immunosorption is a method of blood purification (extraction of antibodies or antigens from complex mixtures using immunosorbents);
• cricothyroidotomy - ensuring patency of the upper respiratory tract in case of obstruction.

When using removable dentures that cause an allergic reaction , the doctor can replace them with structures made of hypoallergenic materials.
