The peri-implant disease results from destructive inflammatory changes in the tissue around a load-bearing dental implant.
Peri-implant disease refers to two conditions: peri-implant mucositis and peri-implantitis. A reversible inflammatory response in the soft tissues around an implant is peri-implant mucositis.
An inflammatory response resulting in an implant’s surrounding tissues losing their supporting bone is known as peri-implantitis.
This article will explore the causes, symptoms, clinical manifestations, diagnosis, and several approaches to treating peri-implantitis.
What is peri-implantitis?
Peri-implantitis is a site-specific infectious condition that results in soft tissue inflammation and bone loss around an osseointegrated implant when it fails to function correctly. It’s essentially the implant equivalent of gum disease, and if left untreated, it can result in bone loss and implant failure. For a few specific implant systems, the overall frequency of peri-implantitis was reported to be 5% to 8%. [4]
The health of the surrounding tissue, the implant’s design, the degree of roughness, the external morphology, and excessive mechanical strain all impact the etiology of implant infections.
Prevalence and risk factors
Many implant patients experience peri-implantitis, which emphasizes the significance of early detection and prevention. The following are risk factors for developing peri-implantitis:
- Inadequate dental hygiene
- Diabetes
- Smoking
- Gum disease history
- Excessive bite forces
The importance of early detection and treatment
Early detection of peri-implantitis symptoms is essential for successful treatment and implant preservation. Early action can repair damage and avoid more severe issues.
Causes of Peri-Implantitis
Inadequate chewing pressure distribution on the surrounding tissues of the implant can also directly cause peri-implantitis, which can loosen artificial supports, infect adjacent tissues, and trigger inflammatory processes. A dental implant’s failure is frequently linked to osseointegration failure.
It is deemed a failure if a dental implant is lost, gets mobile, or shows peri-implant bone loss of more than 1.0 mm in the first year and more than 0.2 mm in the following year. Loss of bone surrounding the implant and the implant itself may occur from peri-implantitis. Replacing the lost implant’s supporting hard and soft tissues is ideal for peri-implantitis treatment.
Bacterial infection and biofilm formation
Peri-implantitis is initiated by the growth of a biofilm surrounding the implant. A biofilm is a complex collection of bacteria enclosed in a protective matrix. The bacteria in this biofilm release harmful compounds that cause the tissues around them to become inflamed. In response to this inflammation, the immune system may cause bone loss, ultimately resulting in implant failure.
Poor oral hygiene and plaque accumulation
One of the leading causes of peri-implantitis is poor dental hygiene. Bacterial plaque collects along the gum line and on the surface of implants. This plaque eventually develops into tartar, which is more challenging to remove. If left untreated, the bacteria in tartar and plaque can irritate and infect the surrounding tissues.
Smoking and other risk factors
One significant risk factor for peri-implantitis is smoking. Nicotine decreases the blood supply to the gums, which weakens the body’s defense against infection. Furthermore, smoking might impair immunity, which makes it harder to fight the bacteria that cause peri-implantitis. Other systemic diseases, including diabetes and osteoporosis, might also raise the chance of getting this illness.
Genetic predispositions and systemic diseases
While the exact role of genetics in peri-implantitis remains to be determined, specific individuals might be more likely to develop the condition. Systemic diseases that impact the body’s immune system and general health, like diabetes and rheumatoid arthritis, may increase the risk.
Symptoms of Peri-Implantitis
Changes in gingival color, bleeding and probing depth of peri-implant pockets, suppuration, X-rays, and progressive loss of tooth-crown bone height point towards periimplantitis.
- Changes in gum tissue appearance: The appearance of the gum tissue around the implant can reveal information about the surrounding area’s overall state of health. Look for indications of swelling, recession, or changes in texture. An implant’s surrounding healthy gum tissue should be firm and pink. Color changes, such as redness or inflammation, may indicate peri-implantitis. Gum bleeding when brushing or flossing is another common symptom. Furthermore, increased peri-implant pockets’ probing depth suggests the progression of the disease and bone loss.
- Pain, swelling, and discomfort around the implant site: You can feel discomfort, tenderness, or swelling around the implant as peri-implantitis progresses. These symptoms may make it difficult for you to go about your everyday life and may lower your quality of life.
- Bleeding and pus discharge: Pus discharging from the implant site is an obvious sign of infection. Even with light brushing, bleeding gums may also indicate peri-implantitis.
- Loosening or mobility of the implant: When peri-implantitis reaches an advanced state, the implant may come loose or shift. This is a severe condition that requires immediate attention. If you encounter these symptoms, you must see your dentist or periodontist for an accurate diagnosis and treatment plan.
Prevention of Peri-Implantitis
The importance of regular dental visits and professional cleanings
Regular dental check-ups and professional cleanings are necessary to maintain optimal oral health and prevent peri-implantitis. Dentists can recognize early inflammation or bone loss indications and provide timely treatment. Professional cleanings remove plaque and tartar buildup that at-home treatment cannot eliminate.
Proper oral hygiene practices and home care routine
It is essential to practice good oral hygiene at home to avoid peri-implantitis. Plaque and food particles can be eliminated from the area around implants by using interdental brushes, flossing, and gentle brushing techniques. Mouthwash can also help reduce oral microorganisms.
Smoking cessation and lifestyle modifications
For both general dental health and peri-implantitis, smoking poses a severe risk. Giving up smoking can significantly reduce the risk of developing this condition. Other lifestyle modifications, such as maintaining a healthy diet and managing stress, can contribute to overall well-being and support implant health.
Early intervention and monitoring of implant health
Implant longevity depends on the early diagnosis and management of peri-implantitis. Patients and dental professionals must regularly monitor the health of their implants. By staying vigilant and seeking professional care, patients can enjoy the long-term benefits of their dental implants and considerably lower their chance of developing peri-implantitis.
Professional examinations: Regular dental check-ups allow dentists to assess implant stability, identify early indicators of peri-implantitis, and provide professional cleanings.
Patient self-care: Patients should perform regular self-exams to check for inflammation, bleeding, or implant loosening signs.
Radiographic evaluations: Periodic X-rays can monitor bone levels around the implant and identify any bone loss.
Treatment Options for Peri-Implantitis
The management of implant infection should focus on infection control, implant surface cleansing, and alveolar bone regrowth. Treatment options vary depending on whether peri-implant mucositis or peri-implantitis is present. They range from non-surgical to surgical interventions.
Nonsurgical interventions (e.g., professional cleaning, antimicrobial therapy)
- Professional cleaning involves using specialized tools to remove tartar and plaque accumulation surrounding the implant.
- Antimicrobial therapy: Using mouthwashes, gels, or local drug delivery devices to reduce the bacterial load.
- Debridement: A thorough cleaning process to remove biofilm and diseased tissue from the implant’s surface.
Surgical procedures (e.g., flap surgery, bone grafting, implant removal)
- Regenerative therapies use growth factors and other materials to stimulate tissue regeneration.
- Flap surgery involves lifting the gum tissue to access and clean the implant surface and remove infected tissue.
- Bone grafting is used to regenerate bone loss around the implant.
- Implant replacement: In severe cases where the implant is compromised, removal and replacement may be necessary.
Maintenance and follow-up care after treatment
Oral hygiene: Continue to practice good oral hygiene at home. Schedule regular visits and professional cleanings at your dentist. Routine monitoring of implant health is crucial to identifying early warning signs of recurrence.
Early intervention and strict adherence to the prescribed treatment plan depend on the longevity of dental implants and the effective management of peri-implantitis.
Possible difficulties and long-term results
If peri-implantitis is not treated, it can cause significant problems and shorten the life of dental implants.
Bone loss: Gradual bone loss surrounding the implant can cause instability and, ultimately, failure.
Implant failure: In severe cases, the implant may come free and need removal.
Adjacent tooth damage: Inflammation and bone loss can impact the health of natural teeth adjacent to the implant.
Infection: Untreated peri-implantitis can lead to persistent infection, which may spread to other body parts.
Long-term Results
Shorter implant lifespan: Peri-implantitis can significantly reduce the lifetime of dental implants.
Compromised aesthetics: Swelling, redness, and bone loss can negatively impact the appearance of the implant and surrounding tissues.
Financial burden: Treating peri-implantitis can be expensive, and implant replacement may be required in extreme circumstances. Persistent inflammation can also result in pain, discomfort, and difficulty chewing.
Prioritizing prevention and timely treatment can increase the long-term prognosis for dental implants.
