Dental implant failure or rejection is when the base of the implant is not permanently integrated with the jawbone, which can lead to severe pain, loosening of the implant, inflammation and swelling of the gums, difficulty in chewing, and even infection. Causes of implant failure include poor bone quality, infection, excessive pressure, smoking, and improper implant selection. If you see these symptoms, you should go to the dentist for accurate diagnosis, appropriate treatment, including infection control, implant removal or reimplantation. Adhering to hygiene and care after surgery is also very important in preventing this complication. It is better to consult a reputable dentist before doing dental implants.

Signs and symptoms of implant rejection or non-union

Emulpent not boiling or repelling has certain signs and symptoms, the most important of which are the following.

Severe and prolonged pain

Pain that begins after implant placement and lasts more than a few days or increases in intensity can be a sign of infection, nerve damage or implant rejection. This pain may be felt in the surgical area and around the implant and requires immediate dental care.

Implant loosening

The implant must remain firmly in place. If you feel that the implant moves a little or feels loose in the mouth, this is probably a sign that the implant is not welded or the implant is not properly integrated with the bone. This condition should be checked and treated.

Difficulty chewing or biting food

If you feel pain, discomfort, or instability in the implant while eating, it may be due to the implant being pushed back. This problem indicates that the implant is not properly seated.

Gingival swelling and inflammation

Swelling, redness, and inflammation of the gums around the implant, especially if it persists, can indicate an infection or inflammatory reaction. If these symptoms are severe or prolonged, you should see a dentist.

Allergic reaction

Allergic reaction may appear with symptoms such as cysts, bumps, or sensitivity at the implant site. If these symptoms occur, you need proper diagnosis and treatment by a doctor.

Gingival depression around the implant

Gingival depression or receding around the implant, which may lead to exposure of the metal base, indicates the beginning of implant retraction and should be checked. This condition increases the risk of infection and reduces the stability of the implant.

Movement and movement of the implant

If the implant moves or displaces, especially if it happens shortly after surgery, this indicates a lack of proper fusion and possibly non-fusion of the implant. This situation requires serious medical action.

Infection and pus at the implant site

The presence of pus, an unpleasant smell, or persistent bleeding is a sign of infection. If the infection is not treated, it can lead to rejection of the implant and damage to the surrounding tissues.

In any case, if you experience any of these symptoms, be sure to see a dentist immediately so that the exact cause can be diagnosed and proper treatment can be performed.

Causes and causes of implant rejection or non-welding

It is not easy for the jaw and bone not to fuse or reject the implant, and there are various reasons that can cause this, and we will mention all these reasons below.

Quality of dental implant materials

Implants are usually made of titanium or zirconia. Titanium implant is very durable and compatible with the body and is considered the gold standard. Zirconia is suitable for patients who are allergic to the metal, but may have a longer healing period. Using low-quality or low-quality implants can cause implant failure.

Unsuccessful jaw bone graft with implant

If the jawbone is insufficient or weak, the implant will not fuse well into the bone. In such a situation, bone grafting is usually required, which, if not done correctly, will cause the implant to reject.

Gum abscess

Bacterial infection in the area around the implant that causes swelling, pain and accumulation of pus. The cause of this problem can be improper oral hygiene, use of low-quality implants, low skill of the specialist and smoking.

Breaking of the implant crown

The crown (artificial tooth on the implant) can break or crack due to excessive pressure, grinding or chewing hard materials. This condition is usually treatable and the crown can be replaced without damaging the implant.

Incidence of nerve or other tissue damage

If the implant is placed near the oral nerves or the nerve is damaged during implantation, it may cause numbness, pain and nerve problems. This damage may be permanent and needs careful examination.

Sinus problems or rupture

In the area of the upper jaw near the sinuses, the implant may enter the sinus or cause a rupture of the sinus membrane. This problem is usually caused by improper surgery or insufficient bone and requires reconstructive surgery.

Autoimmune diseases

In these patients, the immune system may attack the body tissues and the implant or disrupt the healing process, which can cause the implant to be rejected. Immunosuppressive drugs also aggravate this problem.

Poor blood circulation

Low blood circulation in the implant area reduces the healing and fusion of the implant and increases the possibility of infection and rejection of the implant.

Excessive pressure

Excessive pressure on the implanted tooth, such as chewing, grinding and excessive use of the teeth, can cause the implant to break or loosen.

Dental implant root infection

Infection around the implant causes inflammation, bone loss, and eventually failure of the implant. This infection is usually caused by bad hygiene and infections in the mouth.

Gum diseases and bone loss

The presence of gum disease and jawbone degeneration is one of the main reasons for implant failure, because healthy bone and gum tissue are essential for implant stability.

Smoking

Smoking reduces the resistance of the immune system, impairs bone repair and increases infection, all of which increase the risk of implant rejection.

Incorrect care after surgery

Failure to observe oral hygiene, not using prescription drugs, and not visiting the dentist causes infection and weakness in implant welding.

Not having dentist skills

Dentist's low expertise and experience causes mistakes in surgery, improper choice of implant and inability to manage post-surgery problems, all of which will lead to treatment failure.

Implant mismatch

Improperly choosing the type or size of the implant that is not compatible with the patient's oral and bone conditions will cause the implant not to fuse and cause subsequent problems.

Improper molding of the implant

Precise molding is essential for making an implant crown. A mistake in molding leads to a mismatch between the cover and the gum and creates a suitable space for bacteria and infection to enter.

Consequences of not treating rejection or implant failure

• Infection: An unwelded implant becomes a suitable place for the accumulation of bacteria, which can cause a local infection in the gums or jawbone and even spread the infection systemically. Untreated infection may require surgery and implant removal.
• Analysis and damage to the surrounding tissues: Inflammation, ulceration, bone and gum degeneration occur around the implant, which makes the process of repair and reimplantation more difficult and may require bone or gum grafting.
• Implant displacement and loosening: An unfixed implant may move and put pressure on the teeth and jawbone, causing more problems.
• Severe and chronic pain: abnormal pain that increases over time and pain when chewing are symptoms of implant rejection.
• Psychological effects and decreased self-confidence: Dissatisfaction with the appearance of the teeth, especially in the front of the mouth, reduces the quality of a person's social and spiritual life.
• In severe cases, the infection may spread to other parts of the body, which is dangerous for people with weakened immune systems.

Steps to treat implant rejection or non-union

1. Examination and detailed examination with photography to detect the condition of the implant and bone.
2. Removing the loose or infected implant to prevent the spread of the problem.
3. Treatment of infection with medicine and cleaning the implant site.
4. Regeneration of bone and gum tissue if needed with bone grafting.
5. Replanting of the implant after complete healing of bone and gum.
6. Follow-up care and follow-up for the success of the treatment and to prevent the recurrence of the problem.

Prevention of implant rejection

• Maintaining oral and dental hygiene: regular brushing, using dental floss or water flosser, and washing with disinfectant mouthwash are very important to prevent infection and inflammation around the implant.
• Quit smoking and avoiding smoking: smoking reduces the blood supply to the gums and greatly increases the possibility of implant rejection.
• Ensuring gum health before implant placement: If the patient has gum disease, it should be treated first to reduce the risk of infection.
• Detailed examination of jaw bone density: if there is not enough bone, bone grafting is necessary before implant surgery.
• Choosing a quality implant compatible with the body, which is usually made of titanium.
• Implant implantation by a specialist and experienced surgeon.
• Regular visits to the dentist for checkup and periodical care after surgery.
• Adhering to a proper diet and consuming nutrients to strengthen the immune system and the healing process.

Retraction of the implant base

Rejection of the implant base occurs when the connection between the implant and the jaw bone is not established or the surrounding tissues are infected and inflamed. In this case, the bone around the implant degenerates and the implant cannot stay in place and becomes loose. This problem is usually seen more in those who have low bone density or have underlying medical problems.

Implant screw loosening and falling out

Implant screw loosening or falling out is usually caused by mechanical factors such as excessive chewing pressure, teeth grinding, improper screw placement, or infection around the implant. When the screw loosens, the implant may loosen or the crown may fall out. If the screw loosens, you should see a dentist immediately to prevent further damage.

Loose or falling of the implant abutment

Abutment is a piece that connects the implant to the veneer. Abutment loosening or falling out is usually due to impact, excessive pressure, or damage to the abutment itself or the connecting screw. This problem causes the veneer to loosen and the patient's discomfort and must be repaired or replaced by the dentist.
