According to statistics, its prevalence ranges from 3% to 10%. According to the International Congress of Oral Implantologists, it's rare for your body to reject your dental implants. However, this doesn't mean that your dental implant won't fail. A successful dental implant is one that is placed in a healthy bone and is properly cared for after surgery. Dental implant surgery is a highly predictable procedure, with a success rate of up to 97-99%.
However, in between 1 and 3% of cases, implants may not integrate properly. How can you recognize the symptoms of implant rejection? Implant rejection refers to the loosening of the dental implant and the loss of its functionality. This occurs due to inflammation and infection of the soft tissues and bone surrounding the implant. Early implant failure: The implant did not integrate during the osseointegration period (within the first 6 months after placement).
First, the doctor's level of understanding of the nature of bone in different patients. The doctor needs a minimum of 7 years of regular practice to learn to distinguish between different bone tissue biotypes. Without in-depth knowledge of the various biotypes of the mandible, osseointegration of implants is not successful. Second, the ability to learn from one's own mistakes.
The doctor must review his work after 7 to 10 years, identify the cause of the implant failure, draw conclusions and learn from those errors. An expert doctor is not one who only sees your successful cases, but one who analyzes failed cases and constantly improves his approach. At the beginning of my practice in New York, I invited my patients to return 5 to 10 years after the implant was placed to evaluate the results of osseointegration. I learned from my mistakes and consolidated my knowledge through successful cases.
New spongy bone tissue forms around the dental implant, which envelops it and penetrates its porous surface. The newly formed spongy bone around the dental implant is replaced by dense laminar bone. The implant is firmly fixed in the bone and can support a higher chewing load. It can be charged with a permanent crown.
The dental implant becomes an integral part of the jaw. If you feel pain intensifying 7 to 10 days or more after the procedure, it's important to seek professional help. You could run the risk of having your implant rejected. Swollen and inflamed gums 7 days after the procedure are a sign of implant rejection due to infection.
In the first few days after the installation of dental implants, a slight increase in body temperature may occur. The appearance of a discharge of pus under the gum at the site of implant installation is a sign of infection or postoperative rejection of the wound. After a comprehensive examination, the doctor will evaluate your clinical picture. If it is still possible to save the implants, conservative treatment will be provided.
Often, we redo the work of other doctors. We removed the loose implants, placed new ones and placed a couple of new teeth. Tetri complains of constant pain while eating and brushing her teeth. The examination showed that the implants and bridges were incorrectly installed. The bone had atrophied considerably and the implants had become loose.
Tetri decided to perform a complete oral rehabilitation. The treatment lasted about a year. Tetri removed 4 implants from the lower jaw, performed a bone graft and placed 5 implants in the lateral parts of the jaw. All of the upper teeth were removed because they couldn't be repaired. A sinus lift was performed and 7 implants were placed with a complete non-removable prosthesis made of ceramic crowns.
Periimplant pockets form, where pathogenic bacteria accumulate and leftover food. Due to an incorrect shape of the crown, the bite is overadjusted or underadjusted, causing constant overload of the implant. Inflammation develops, increasing the risk of peri-implantitis. Microspaces remain between the implant and the abutment or between the abutment and the crown, where food debris and pathogenic bacteria can be deposited.
During the first few days after the placement of the dental implant, it is important for the patient to strictly follow the doctor's recommendations, such as avoiding physical exertion and showers with hot water. Failure to comply with these recommendations during the rehabilitation period often leads to implant failure. Tobacco smoke contains substances that narrow blood vessels. Smoking for the first 4 to 6 weeks after dental implant placement increases the risk of rejection.
The soft tissues surrounding the implant will suffer from a deficiency of the nutrients needed for normal osseointegration. The suppression of the functions of the salivary glands contributes to the active reproduction of pathogenic microflora in the mouth. The accumulation of pathogenic bacteria around the dental implant leads to infection of the soft tissues of the gums - mucositis. In the absence of treatment, the inflammatory process leads to the destruction of soft tissues and spreads to the bone.
Periimplantitis develops and bone tissue decreases, causing the implant to loosen. The excellent training of our specialists and the modern equipment allow us to perform very complex operations: complete oral reconstruction and implantation of all teeth in one day. Before installing the implant, we always carry out professional dental cleaning: ultrasonic and with air flow. We remove plaque and calculus from the teeth.
If there are periodontal pockets, we do a deep cleaning with scales. We use a unique PIC technology. We fix the exact position of the installed dental implants. In the Exocad program, we adapt the implants with a virtual model of new teeth to correctly distribute the chewing load.
We eliminate the risk of implant rejection due to an overload. We manufacture new teeth in our dental laboratory with an accuracy of up to 5 microns. We perform gum plastic surgery after implantation. We recreate an aesthetic contour of the gums.
We provide nutrition to the bone surrounding the implant and protect the area where the implants are implanted infections. We eliminate exposure to the implant neck and reduce the risk of peri-implantitis. Fortunately, the body almost always accepts properly prepared and installed dental implants. Across the country, success rates are around 95%, so if you're considering getting a dental implant, don't let the fear of rejection stop you.
Some studies show that between 5 and 10% of dental implants fail a few days or weeks, months or years after the procedure. Implant rejection can occur months or even years after placement. Early rejection usually occurs due to infection, poor osseointegration, or an immune response. Late rejection may be due to bone loss, systemic conditions, or excessive pressure on the implant over time.
Dental implant failure is the body's inability to establish or maintain osseointegration, a process in which bone fuses with implants. Dental implant surgery can be an immediate success, and complications don't develop until years later. Usually, when a dental implant is rejected, it's not because the implant itself is rejected, but because there's another problem at play. By adopting these habits, you can extend the lifespan of your dental implants and reduce the risk of failure.
If you have bacteria in your jaw at the time of placing your dental implant, they can spread from one implant to another and cause the dental implant to fail. Dental implants are screw-shaped metal posts that are placed by oral surgery to hold one or more replacement teeth. Although dental implants are made of biocompatible materials such as titanium or zirconia, certain factors can cause implant rejection or complications over time. On average, less than one percent of potential dental implant recipients reported being allergic to titanium.
Dental implant failure is classified as early and late failure, depending on the time when complications arise. The integration of a dental implant, or osseointegration, is the process in which the implant fuses with bone. This means that your body should not react to the dental implant; however, rejections do occur from time to time. Understanding the causes of dental implant failure, recognizing early warning signs and taking preventive measures can help you maintain long-term implant success. The rejection of a dental implant is a destructive pathological process characterized by inflammation, resorption and loss of the already formed bone tissue surrounding the intraosseous part of the implant.
Dental implants are small metal posts that are surgically placed in the jaw bone by a dentist or oral surgeon.
