Symptoms and causes of dental implant rejection: why doesn’t it take root and is it possible an allergy? What to do if a screw in a crown comes loose What to do if an artificial tooth root becomes loose

Any system breaks down over time, and dental implants are no exception.

A dental implant is a technical structure that consists of several parts fixed together into a common system. The most commonly used diagram of the technical design of a dental implant is:

• The abutment is secured to the implant body using a securing screw.
• An artificial crown is fixed to the base of the abutment using dental cement.

The most common failures are fractures of the securing screw. Dental implants rarely fail. If the screw breaks, you can save the implant. If the body of the implant is deformed, a new one has to be installed.

To prevent dental implant from breaking, you must follow the doctor’s recommendations. There is no need to eat solid food after the implant is installed. Also, the implantability of an artificial root largely depends on the material from which it is made.

Today, titanium is considered the most reliable. It has a high survival rate. Many manufacturers claim that such systems will last more than 50 years.

Rejection symptoms:

• the wound bleeds for four days,
• redness and swelling of the gums,
• severe pain that is not relieved by painkillers,
• the presence of pus in the implant installation area.

What to do?

As soon as you notice discomfort in your mouth, consult your doctor immediately. The word implant fell out means the separation of the crown. The screw itself cannot come off because it is firmly embedded in the bone. The prosthesis may fall out due to unskilled work of the doctor and if the recommendations were not followed.

The doctor is required to monitor the installed system for several years. It is during this period of time that various complications may appear.

In such a situation, the doctor immediately prescribes the necessary treatment. In order not to worry about rejection, you need to wisely choose a clinic and a doctor, making sure of his qualifications.

If you contact the NEW AGE clinic, you will receive high-quality installation of reliable implants.

Professional surgeons and orthopedists will install perfect and reliable implants from popular manufacturers at an affordable cost.

Name: Anton

Attending doctor: Kalaichev Alexey Demosthenovich

I had a tooth removed at the clinic today by the attending physician - Alexey Demosfenovich Kalaychev. I would like to note the professionalism of the doctor; he dealt with the tooth quickly, without discomfort or pain, and administered anesthesia very carefully. I’ll try not to let it get deleted again, but if I still need to delete it, then only go to him!

Name: Khabarova Nadezhda Vladimirovna

Attending doctor: Bugaev Sergey Sergeevich

Doctor Sergey Sergeevich Bugaev put a crown on me 6 months ago. It doesn't bother me and is identical to a regular real tooth. I also installed the Nobel implant, and there were no unpleasant sensations. I liked the fact that I didn’t have to wait long for my turn. I like everything about the NEW AGE clinic.

Name: Marina

Attending doctor: Razumeiko Daniil Alexandrovich

I contacted “NEW AGE” a year ago to install implants. We spent a long time choosing implants, and eventually settled on the German Ankylos. The installation was successful, nothing hurt during and after surgery. Thanks to Daniil Aleksandrovich Razumeiko for his professional and sensitive work. Soon I will need to get a crown, so I have already made an appointment with him. Thanks a lot!

Any surgical intervention, even in the modern world of high dental technologies, can lead to complications. And not everything is due to the quality of the materials used. What to do if it falls out, who to turn to for help, and is it possible to restore the chewing function of teeth again?

Causes

There are many established or recently installed artificial roots from. Among them:

1. Poor quality raw materials in the manufacture of the implant.
2. Violation of the installation protocol or non-compliance with its sequence by the implantologist.
3. Neglect of doctor's recommendations and failure to comply with personal hygiene by the patient.
4. Individual intolerance to the materials from which the sample is made.
5. Development of complications for reasons beyond the control of the doctor and patient.

In general, implant rejection is a pathological process that leads to loss of connection between the tissues of the jaw and the artificial root. This development of the situation is recognized as the most serious complication after prosthetics.

Approximately 10% of cases out of 100 are accompanied by rejection, which lasts approximately 2-4 months in the lower jaw and about six months in the upper jaw, due to its complex structure. The healing period directly depends on the individual characteristics of the patient’s body and the material from which the prosthesis is made.

Medical errors

If the implant falls out due to the doctor’s fault, this usually happens in the first two weeks after installation. The following factors may influence this:

• overheating of the bone with a drill;
• nerve ending injuries;
• incorrect choice of design;
• small thickness of the jaw bone;
• ignoring the preparatory stage;
• incomplete examination of the patient's medical history;
• violation of antiseptic measures.

Features of the patient's body

This aspect is partly the doctor's fault and partly the patient's fault. However, both parties may not be aware of the presence of such an unpleasant factor. The reasons may include both the characteristics of the body and the presence of any diseases:

1. poor immunity;
2. structural features of the maxillofacial region;
3. sensitivity to foreign bodies in the body;
4. allergic reactions;
5. aggravated form of chronic ailments;
6. untreated dental units;

Irresponsible attitude

In practice, there are quite often cases of rejection due to the patient’s negligence. The fact is that some people think that a new tooth has been installed and you can be calm. But this is by no means true. Failure to follow recommendations and lack of care lead to complications in the postoperative period and even loss of the structure. The reasons are banal:

• drugs and alcohol;
• non-compliance with recommendations for proper nutrition;
• refusal to take preventive medications;
• sudden temperature changes after installation of the prosthesis;
• lack of oral hygiene;
• refusal to regularly visit the dental office;
• selection of analogues, dosage violations or uncontrolled use of drugs.

The most dangerous complication is reimplantitis (viral infection of bone and soft tissue around the installed prosthesis).

Symptoms

When the rejection process begins, the patient develops primary symptoms, expressed by pain, swelling, discomfort, etc. If you do not consult a doctor in time, the number and intensity of symptoms increase:

1. mobility of the prosthesis;
2. in the area of ​​artificial root;
3. increased body temperature;
4. changes in the gum cuff, including inflammation.

If you do not want your dental implant to fall out, rush to see a doctor even when the first symptoms that are unusual for your usual state of the body appear.

It also happens that the cause of rejection may be an allergy to titanium root:

• inflammation of the salivary glands;
• sore throat;
• ulcers and microcracks on the mucous membrane;
• metallic or bitter taste;
• increased salivation or, conversely, dryness;
• coating on the tongue.

Diagnostics

If a tooth implant falls out without the appearance of any symptoms, which is extremely rare, or if the first symptoms and discomfort begin to appear, you should immediately seek help from a doctor.

To obtain a complete clinical picture, the prosthetist must perform the following manipulations:

1. initial examination and hearing of patient complaints;
2. X-ray image;
3. CT scan;
4. collection and examination of biological material to determine the type of bacteria;
5. various tests and studies to identify allergic reactions and the presence of inflammation.

When conducting a diagnosis, the doctor must understand whether complications are present after the onset of the rejection process, and what could be the reason for its formation:

• cystic suppuration;
• development of inflamed reimplantitis;
• periostitis;
• mucositis.

Treatment

Upon receipt of a complete clinical picture, the doctor prescribes treatment. If there is a chance of recovery, the prosthetist carries out all the necessary procedures to eliminate inflammation and infectious diseases that can lead to complete rejection.

When it is impossible to change the irreversible consequences that have begun, a reimplantation procedure is prescribed. However, not everything is so fast. First, you need to undergo a full course of rehabilitation, including drug treatment and, if necessary, and only then after about six months you can again think about installing a new denture.

Drug treatment involves taking antiseptics and antibiotics, following certain hygiene procedures, rinsing the mouth with special medical solutions, as well as careful care of the wound canals.

1-2% of implants do not take root. This is normal, and this is a fairly small percentage of the risk. As a rule, implant rejection occurs without pain, and the clinic performs re-implantation. Free or for money – it’s better to find out in advance. Implant manufacturers usually provide a warranty.

EARLY REJECTION

The first six months after installation, the implant grows into the bone. It may not take root: then you’ll just have to try again. This is a normal situation, although quite rare.

Even in a completely healthy person, an implant installed by an experienced surgeon may not take root. This happens very rarely, in one case out of 300. No one knows why this is so.

Implant rejection is painless and often the patient does not even notice it. Sometimes the patient himself, feeling mobility, takes it out. Sometimes during a follow-up examination the doctor unscrews a rejected implant. Next, re-implantation is scheduled in agreement with the patient.

Pain is possible in exceptional cases when the implant is installed in the wrong position, in violation of the surgical protocol. But in this case, the implant is removed immediately, there is no question of any engraftment. This can only be assessed on an x-ray.

Possibility of rejection

According to statistics, one or two implants out of a hundred are rejected.

It depends:
from the general health of the patient;
from compliance with medical recommendations;
on the volume of surgical intervention;
on the choice of implantological system;
doctors' experience with this system.

For some patients (for example, those with diabetes), the risk of rejection may be higher. The doctor will definitely warn you about this.

However, even in high-risk patients, implantation is often successful. You yourself can influence the likelihood of engraftment by following all the doctor’s recommendations and prescriptions.

LATE REJECTION

Later, there should be no problems with the implant - if it is correctly installed, properly cared for, and its owner does not suffer from serious illnesses or injuries. Sometimes, even in later stages, implant rejection is possible.

It may be caused by:
medical error (incorrectly placed implant, poor prosthetics, cheap non-original components, etc.);
mechanical trauma, increased load on the implant, bruxism;
poor oral hygiene;
development and exacerbation of certain diseases (oncology, diabetes, immune diseases).

Symptoms of late implant rejection are gum redness, swelling, pain, and bad breath.

In any such situation, you should contact your doctor. If this is not possible, go to the nearest dentist.

Fracture

There is no need to be afraid of an implant fracture. Titanium and its alloys are very durable materials. Implants break extremely rarely (about one in 30,000) and only as a result of serious injury.

Guarantees

Serious manufacturers offer a lifetime guarantee – you won’t have to pay for a new implant. If the clinic includes insurance against such failures in the cost of the service, then the operation will be free.

Ask your doctor in advance:
is there a guarantee for the implant;
Do the clinic's rules provide for free reinstallation?

Note:

... the price of implantation that is initially too low most likely indicates a lack of insurance. This means that if the implant fails, you will have to pay for the entire treatment again. The more popular implants you have, the higher the likelihood of receiving help anywhere in the world. Choose those brands that are found not only in one clinic in your city.

CONCLUSIONS

So, to avoid problems with the implant in the future, you need to:
from the doctor - do your job well;
It’s up to you to take care of the implant and avoid excessive loads on it.

To ensure that problems, if they do arise, are resolved quickly, efficiently and without unnecessary costs, the main thing is:
choose a good clinic;
choose a good implant from a well-known manufacturer.

After dental implantation, there is a risk of complications, including implant rejection. This phenomenon is associated with various factors, most often poor survival rate is the result of an error during the operation and the lack of preventive measures in the early period after installation of the implant. Failure of a dental implant is accompanied by a number of unpleasant symptoms, which are important to recognize in time in order to provide timely assistance and choose an alternative option for dental restoration.

Symptoms of dental implant failure may appear in the early postoperative period, 2-14 days, and up to a year after the procedure. A complication factor in the later period is the increased load on the structure and bone tissue atrophy. There are a number of rules and recommendations that help avoid the consequences of implantation and promote normal implantation.

The complication occurs in 2 patients out of 100, even with proper preparation and compliance with all stages of titanium pin installation. It is difficult to determine in advance whose implant will not take root, because this may be influenced by a seemingly insignificant factor.

Why does implant failure occur?

Normally, after surgery there are mild symptoms. For a week, the patient experiences tissue swelling, foreign body sensation, pain, and redness of the gums. If these phenomena do not go away on their own, there is already a reason to undergo an unscheduled examination by your doctor and find out the cause of prolonged discomfort.

You should contact your dentist if the following symptoms appear:

• pain syndrome for more than 14 days;
• inflammation of the gums in the area of ​​the operation;
• implant mobility;
• discharge of pus from under the gums;
• bleeding from the wound for more than a week.
• general symptoms of illness.

When a dental implant is rejected, it begins to wobble, but this does not happen immediately. At first, pain, inflammation and swelling of the tissues begin to worry, then the symptoms increase, and the pin begins to loosen.

Implants do not take root well for the following reasons:

• medical errors;
• low-quality prostheses;
• lack of postoperative care;
• systemic diseases;
• jaw injuries.

Medical errors and patient guilt

The implant takes root painlessly, within two weeks all unpleasant symptoms disappear, which indicates a normal reaction of the tissues of the oral cavity and the whole body to a foreign body. But something can go wrong, and after the implant is installed, the gums begin to swell, bleed and hurt.

Most of the complications of implantation occur due to the fault of the doctor:

• choosing the wrong implant;
• insufficient assessment of bone tissue condition;
• ignoring the rules of asepsis;
• overheating of tissues during bone drilling;
• ignorance of the patient’s life history and illness;
• lack of preliminary sanitation of the oral cavity.

What actions can a patient take to cause complications:

• overload of the titanium pin during the healing period;
• refusal to take prescribed antibiotics and anti-inflammatory drugs;
• lack of oral hygiene;
• ignoring the rule about quitting smoking in the first days after surgery.

Large dental centers specializing in implantation usually work with trusted suppliers of dental instruments and materials, so implantation complications due to poor-quality implants are excluded. But small clinics may try to save on quality.

Nowadays, titanium is the best option for dental implantation. The material has a porous structure, so healing occurs stably, bone tissue penetrates into the implant, ensuring reliable fixation of the pin. For aesthetic reasons, zirconium dioxide can be used, but its degree of osseointegration is significantly inferior to titanium, which can become a rejection factor.

Early and late complications

Implantation occurs in several stages. First, the implant is implanted, and after the wound has healed, an abutment is installed - the base for a prosthesis or artificial crown. When implants fail, it is accompanied by peri-implantitis - inflammation of the tissue around the titanium post.

Complications at the implantation stage occur for the following reasons:

• hemorrhage with wound suppuration;
• inaccurate tissue preparation;
• poor wound closure;
• poor oral hygiene;
• infectious and purulent focus.

To prevent these conditions, professional hygiene and sanitation of the oral cavity are carried out. The dentist cannot begin direct implant installation when he is not sure that the condition of the mucous membrane, teeth and periodontal tissue meets all the required parameters for surgical manipulation. In some cases, it takes several weeks or even months to create all the conditions for safe and high-quality implantation.

Systemic disorders and conditions that can cause rejection:

• diseases of the hematopoietic organs, blood clotting disorders;
• diabetes mellitus, hyperglycemia;
• malocclusion and bone deformation;
• age up to 16 years;
• severe chronic periodontal diseases;
• immunodeficiency, HIV infection, hepatitis;
• benign and malignant neoplasms in the body;
• pathologies of the nervous system and heart;
• systemic connective tissue disorders.

These are relative contraindications to implantation, which are considered individually. During the period when the pathology subsides and if you feel well, treatment can be carried out, but the risk of developing various complications remains.

The implant can take root poorly when the doctor or patient ignores the importance of preventing not only complications from the oral cavity, but also systemic pathologies that can worsen after surgery.

Complications at the stage of abutment installation:

• unscrewing the pin with the plug– occurs as a result of rejection or re-implantitis, the implant first wobbles, then comes off completely, calcium supplements are prescribed for treatment in order to restore bone tissue;
• exit of the implant into the maxillary sinus– this happens during implantation in the upper jaw, when the installation technique is not followed or there are bone tissue disorders, in which case the pin is removed;
• overgrowth of the implant with bone tissue– the pin is covered with bone, but this happens extremely rarely, and to prevent this, a gum former is installed during the implantation process

Signs of implant rejection

The implant takes root within a year, but its rejection most often occurs in the early period - the first 6 months after surgery. Symptoms that appear after 2-3 years or even 10 years are more likely to indicate other problems in the oral cavity or with bone tissue. Typically, dental implant failure results in symptoms consistent with oral infection and inflammation.

How to understand that there are problems with implant healing:

1. A week after surgery, pain remains. Normally, the pain goes away after 3-5 days; anti-inflammatory drugs are taken for pain relief. If the symptom does not subside, you need to go to the doctor to find out the cause.
2. Gum swelling persists. Light swelling is present for several days, and if the inflammatory process does not begin, the swelling goes away without a trace.
3. Pain when pressing on the gum. This is an important sign of poor implant healing. The symptom may be accompanied by a sensation of pulsation, in which case additional treatment will probably be necessary, possibly with removal of the implant.
4. Structure mobility. Normally, the pin is well fixed in the bone, which completely eliminates its mobility. Violation of the position of the prosthesis and its free movement indicates rejection due to an error during installation.
5. Bleeding from a wound. Periodic bleeding from the wound continues for 3-7 days. If this phenomenon bothers you for more than a week and you feel a constant metallic bite in your mouth, you should go to the dentist.

What to do when the implant does not take root

When the cause of rejection was a doctor’s mistake, it is better to undergo examination by several specialists. Each dentist has his own approach to work; some may adhere to outdated implantation technology and not delve into modern treatment methods, ignoring the important stages of preparation and postoperative management.

When poor hygiene or health problems become a complication factor, then you should continue treatment with the specialist who installed the implant, because he will better understand what needs to be corrected to solve the problem.

Any mechanism is prone to breakdowns, unfortunately dental implants are no exception.

A dental implant is a technical structure consisting of several elements interconnected into a single mechanism. Here is the most commonly used formula for the technical design of a dental implant:

• fixed to the implant body using a fixing screw;
• fixed to the surface of the abutment using dental cement.

According to the frequency of observed breakdowns, the most common fractures of the fixing screw. Dental implants are less likely to break. If the screw breaks, it is possible to save the implant. If the body of the implant breaks, a new one has to be installed.

Broken dental implant

To illustrate the complication of “breakage of a dental implant”, let us give an example from the clinical practice of CKS dentistry.

The photo shows that the patient is missing the second upper premolar of the maxilla. According to the patient, about 5 years ago in one of the Kyiv clinics he had an implant installed in the place of the extracted tooth. For five years he used the artificial tooth perfectly and did not feel any discomfort. But suddenly the tooth began to “loose” and soon “fell out.”

The photo shows the part of the implant that ended up in the patient’s hands after the breakdown. The part to which the abutment and crown were fixed with a screw broke off from the implant.

The numbers in the figure indicate:

• 1 - metal-ceramic crown;
• 2 - abutment;
• 3 - fragment of the implant.

Why was such a breakdown possible? And why did the implant break in this particular place?

From the point of view of the science of "strength" everything is quite logical. The highest loads occur at the connection to the abutment in the implant. And the cross section of the implant is the weakest.

The fracture occurred in the area from point 1 to point 2 (implant neck). It is this section of the implant that ensures the retention of the abutment, and therefore the crown. In this section, the implant is hollow - it is a thin ring, this is clearly visible in the section. Therefore this area is weak. Thus, in the place where the highest loads occur, the implant has the weakest cross-section. It is not surprising that the implant broke in this exact location.

How to avoid dental implant fracture?

1. The formula for success turns out to be very simple - you need to choose only high-quality dental implants. There are about 2000 implant systems in the world. But you can only choose from 64 systems. Why you can’t trust more than 1900 systems, read our article.
   The price of a dental implant should reflect the precision of the connection between the implant and abutment. The more accurately the connection is made, the longer the structure will withstand chewing loads. When chewing, a person does not develop high efforts. But the complexity of the situation lies in the fact that these small loads are repeated millions of times in just one year of operation. In engineering, failures caused by constantly repeating, cyclic loads are called fatigue failures. Over millions of cycles, the metal loses its harmonious structure. So-called dislocations appear and accumulate in it, which then turn into microcracks. Next comes destruction - breakdown.
2. When making prosthetics, it is necessary to select the sizes of dental implants according to the requirements of the manufacturer. In our case, for chewing teeth, the diameter of the implants should be at least 5 mm.

In our patient, both principles were violated. The implant was too thin - only 4 mm in diameter. The implant manufacturer was not chosen from a reputable category.

X-ray of a patient with a broken implant. It is obvious that the dental implant is perfectly integrated with the bone tissue. It is surrounded by healthy bone. Integration is what patients call “engraftment.” According to patients, this implant has taken root well, because it lasts 5 years.

This picture is a good illustration of the postulate that it is not as difficult to achieve implant engraftment as it is difficult to achieve long-term successful functioning of a dental implant.

The green rectangle indicates the missing part of the implant in the image. Although the implant is perfectly integrated, it cannot be used. Without the missing fragment, it is impossible to fix the abutment and crown to it.

What to do if the implant breaks?

I would like our article to carry a positive charge for patients. We want to demonstrate that complications arising during implant treatment can and should be corrected. Patients often do not think about the fact that complications can occur in any treatment. It seems to them that all the troubles can only be associated with surgical treatment.

Let's remember that dental fillings can fall out, and root canals can be poorly filled... These are also complications. They are overcome. The filling is placed again, and the canals are re-treated. The same is true with dental implants. We will correct the complication of “implant failure” by replacing the implant.

For the purpose of a complete diagnosis, we conducted a CT scan and discovered that there was another complication of the previous treatment. Chronic inflammation of the maxillary sinus.

In the image, number 1 indicates thickening of the maxillary sinus mucosa, indicating an inflammatory process in the maxillary sinus (chronic sinusitis). The reason for this inflammation is the location of the implant close to the maxillary sinus, indicated by the number 2.

How to avoid the complication of “chronic sinusitis” when installing a dental implant?

Often patients look for any explanations and reasons not to do an open sinus lift. They are looking for a doctor who will agree to perform a closed sinus lift rather than an open one. Patients are frightened by the word open; they see hidden danger in this word. In fact, the opposite is true. The disadvantages arise from the fact that in the case of a closed sinus lift, the doctor is forced to carry out the manipulations “blindly”. This clinical case illustrates well the possible complications of a “closed” sinus lift.

Judging by the CT scan, the dental implant was installed using the closed sinus lift technique. In the illustration, arrow “2” indicates the adherence of the implant to the bottom of the maxillary sinus. There is no bone structure above the implant. This suggests that the Schneiderian membrane was perforated during implant placement. If the previously performed sinus lift had used an open protocol, then such a complication would not have occurred.

Treatment plan: eliminating complications

• removal of a broken implant;
• and eliminating the cause of chronic odontogenic sinusitis.

It may seem strange that a patient has encountered treatment complications and still wants a dental implant.

• The first thing I would like to draw your attention to is that the patient does not have fillings. One small one in the "seven" on the left. Therefore, the patient does not want to hear anything about drilling teeth to make a bridge or something similar.
• Second. The patient used the implant for five years. He believes in implantation as a treatment option. He attributes the complication, in the form of a broken dental implant, to the fact that he had a bad implant installed.
• Third. The patient’s life experience provides clear confirmation that the use of implants does not harm neighboring teeth in any way, and we instill in him the belief that the situation with implant failure can be corrected.

Cost of dental implantation in Kharkov

The cost of a full cycle of dental restoration using implants is described in detail in the section “Prices for dental implantation”. The cost of the CKS dentistry service includes all necessary procedures and manipulations, including the work of a dental technician (prices without hidden fees)

Treatment procedure:

1. Dental intervention was preceded by treatment with an ENT doctor. The inflammatory process was stopped.
2. A broken dental implant was removed.
3. An open sinus lift was performed (the future implant was separated from the maxillary sinus with a special membrane and osteoplastic (bone replacement) material). This will avoid the appearance of inflammatory processes in the sinus in the future.
4. A new dental implant was installed.

Surgical intervention to replace a broken implant and perform an open one:

Surgical treatment does not require large incisions or extensive exposure to surrounding tissue. As in any other situation, we try to keep the intervention minimal.

After making the incision, the end of the broken implant becomes visible (indicated by an arrow in the photo).

The implant is integrated with the bone tissue and is not easy to remove. It is important that during implant removal, the bone is preserved as much as possible, otherwise it will be impossible to install a new implant.

The photo shows a removed dental implant. The use of special instruments allowed us to minimize bone loss.

The next step is a sinus lift.

The photo illustrates the progress of the operation, the numbers indicate:

1. - cavity formed as a result of implant removal;
2. - access window to the maxillary sinus from the outside of the upper jaw;
3. - sinus mucosa (Schneider's membrane) raised above the surface of the sinus.

Next stage of the operation:

The result obtained after the treatment corresponds to the result of the first stage of dental implantation (in the terminology of the two-stage dental implantation protocol).

After 6 months, the second stage of dental implantation will be carried out according to the standard protocol. Then the manufacture of an abutment and a ceramic crown.

Once again about why a broken dental implant could not be used. Now we have cleaned the dental implant from the bone tissue into which it was perfectly integrated and we can clearly see it.

In the photo: 1. - a larger fragment of a dental implant, 2. - a smaller fragment of a dental implant, 3. - an abutment.

Two different photos clearly demonstrate that the abutment and the dental implant fragment can be connected and precisely aligned using the so-called external hexagon. But the fracture line between fragments “1” and “2” of what was once a single dental implant cannot be restored.

Conclusions:

To avoid dental implant failures, you should:

1. Give preference to implants from reputable manufacturers who control the full production cycle of implantological products;
2. Select dental implant sizes by strictly following the implant manufacturer's recommendations.

1. A complication in the form of a broken dental implant can be eliminated, but this requires a separate surgical intervention.

We tell you how to choose an implantation system in the article.
