Quick answer
Peri-implantitis is an inflammatory condition affecting the tissues around a dental implant, leading to bone loss if untreated. It differs from mucositis, which is limited to soft tissues. Treatment ranges from non-surgical cleaning to surgical intervention, depending on severity. Prevention through meticulous oral hygiene and regular professional reviews is essential.
What is peri-implantitis?
Peri-implantitis is a destructive inflammatory process that affects the soft and hard tissues surrounding a dental implant. It is characterised by inflammation of the gum (mucosa) and progressive loss of the supporting bone. If left untreated, it can lead to implant failure. Understanding this condition is crucial for anyone considering or already living with dental implants.
How does peri-implantitis differ from mucositis?
Mucositis is a reversible inflammation confined to the soft tissues around an implant, similar to gingivitis around natural teeth. It presents with redness, swelling, and bleeding on probing, but there is no bone loss. Peri-implantitis, in contrast, involves bone loss and requires prompt intervention. The key distinction is that mucositis can be reversed with improved oral hygiene and professional cleaning, whereas peri-implantitis demands more advanced treatment to halt disease progression.
What causes peri-implantitis?
The primary cause is bacterial plaque accumulation, similar to periodontal disease. Risk factors include poor oral hygiene, smoking, diabetes, a history of periodontitis, and poorly designed or placed implants. Other contributing factors may include cement residue left after crown cementation, occlusal overload (excessive biting forces), and genetic predisposition. It is a multifactorial condition, meaning multiple elements often interact to initiate and propagate the disease.
What are the symptoms of peri-implantitis?
Early signs include redness, swelling, and bleeding when brushing or probing around the implant. Patients may notice a bad taste or halitosis. As bone loss progresses, the implant may become mobile, and pus may discharge from the gum pocket. However, the condition can be asymptomatic in its early stages, which is why regular professional reviews are vital. If you experience any of these symptoms, seek evaluation promptly.
How is peri-implantitis diagnosed?
Diagnosis involves a clinical examination and radiographic assessment. Your dentist or specialist will probe the gum pockets around the implant. There is no single depth that separates health from disease around an implant: what matters is whether the pockets are deeper than they were at earlier visits and whether they bleed on gentle probing, which is why the readings are recorded each time rather than judged in isolation. X-rays (periapical or panoramic) are used to measure bone levels and detect bone loss compared to baseline images taken at implant placement. Early detection is key to successful treatment.
What are the treatment options for peri-implantitis?
Treatment depends on severity and is categorised as non-surgical or surgical. The goal is to eliminate inflammation, arrest bone loss, and preserve the implant.
Non-surgical treatment
For early peri-implantitis or mucositis, non-surgical therapy includes professional mechanical debridement using specialised instruments (e.g., titanium or plastic curettes, ultrasonic scalers with plastic tips) to remove plaque and calculus without damaging the implant surface. This is often combined with antimicrobial irrigation (e.g., chlorhexidine) and improved home care. The patient must be instructed in meticulous oral hygiene, including the use of interdental brushes and water flossers. A course of systemic antibiotics may be prescribed in some cases, but this is not routine.
Surgical treatment
If non-surgical therapy fails or bone loss is advanced, surgical intervention is required. Procedures include flap surgery to access the implant surface, debridement, and decontamination using methods such as air-powder abrasion, titanium brushes, or laser therapy. In cases with significant bone loss, bone grafting (using autograft, allograft, or xenograft) may be performed to regenerate lost bone. The implant surface may be modified or replaced if damage is extensive. In severe cases where the implant is no longer salvageable, explantation (removal) may be the only option.
How can peri-implantitis be prevented?
Prevention starts before implant placement. Patients with a history of periodontitis should have their gum disease treated and stabilised first. After implant placement, a rigorous oral hygiene routine is essential: brushing twice daily with a soft toothbrush, flossing or using interdental brushes, and irrigating with an antimicrobial mouthwash if recommended. Regular professional maintenance visits every 3–6 months allow your dentist to monitor implant health, perform professional cleaning, and take periodic radiographs to detect early bone loss. Smoking cessation and good diabetic control are also critical preventive measures.
Whoever places your implants, there are a few things worth settling in advance, because they determine whether peri-implantitis can be caught early. Ask for the radiograph taken on the day of placement — this is the baseline every later X-ray is compared against, and without it bone loss can only be guessed at. Ask which implant system and abutment were used, and keep the record. Ask how excess cement will be avoided or removed, since retained cement is a well-recognised trigger. Finally, agree who will carry out your three- to six-monthly maintenance visits, and make sure that person has your records.
Patients treated abroad should settle the last point before travelling rather than after: a maintenance programme that nobody at home has agreed to provide is not a maintenance programme. Peri-implantitis also cannot be assessed remotely — probing depths and bone levels require an in-person examination and a current radiograph. If you are considering treatment in Turkey, Taki Dent in Antalya is this guide's disclosed partner clinic and assesses implants for patients enquiring from the UK.
Frequently asked questions
Can peri-implantitis be cured completely?
Yes, if caught early, treatment can arrest the disease and preserve the implant. Advanced cases may require surgery, and while bone loss cannot be fully reversed, further deterioration can be halted with appropriate care.
Is peri-implantitis painful?
Peri-implantitis is often painless in its early stages. As it progresses, you may experience tenderness, swelling, or discomfort. Regular check-ups are important because you might not notice symptoms until significant damage has occurred.
How often should I have my implants checked?
It is recommended to have professional reviews every 3 to 6 months, depending on your risk factors. This allows your dentist to monitor implant health and perform preventive cleanings.
Can peri-implantitis cause implant failure?
Yes, if left untreated, peri-implantitis leads to progressive bone loss and can ultimately result in implant mobility and failure. Early treatment is crucial to avoid this outcome.
Are smokers at higher risk for peri-implantitis?
Yes, smoking significantly increases the risk of peri-implantitis due to impaired healing and reduced blood flow. Smokers are advised to quit or reduce smoking to improve implant prognosis.
What is the success rate of peri-implantitis treatment?
Outcomes vary a great deal with how early the disease was caught, how much bone has already been lost and how well plaque is controlled afterwards. Non-surgical cleaning can arrest early disease in many patients; more advanced bone loss usually needs surgical access to decontaminate the implant surface, and neither approach holds without ongoing maintenance. Published figures differ widely because studies define success differently and follow patients for different lengths of time, so ask your clinician what is realistic for your own case rather than relying on a headline percentage.
