Introduction — Are Dental Implants Safe?
Yes. Dental implants are among the most successful surgical procedures in modern medicine — with success rates between 95 and 99% at 10 years with proper indication and aftercare. For comparison: many purely orthopaedic procedures (hip, knee prosthesis) are in the same range.
But: no medical procedure is 100% complication-free. In 2-5% of patients, complications occur over the years — from harmless, quickly treatable swellings to implant losses. The good news: most complications are predictable, preventable, and well-treatable — when detected early.
This article is an honest, evidence-based explanation of possible complications: what they are, why they arise, how we treat them, and — most importantly — how we prevent them. We believe that informed patients achieve the best clinical outcomes.
If you're considering an implant treatment in Poland or already have an implant and are concerned about complications, you'll find here structured information for an informed decision.
Early vs. Late Failures — The Important Distinction
Complications in implantology are categorised by time of occurrence. This distinction is critical for diagnosis and treatment.
Early Failures (Within 3-6 Months After Placement)
The implant fails during osseointegration — the phase in which it should normally integrate with the bone. Typical causes:
Frequency: approximately 1-3% of all implants. Detection: the implant is loose or painful — we gently remove it, the bone heals (3-4 months), then we place a new implant — usually successfully.
Late Failures (After Completed Osseointegration)
The implant was osseointegrated and functional, but complications develop over months to years. Main causes:
Frequency: approximately 2-5% of all implants at 5-10 years.
The Most Common Complications Overview
Peri-Implant Mucositis (Reversible)
What it is: Inflammation of the soft tissue around the implant — analogous to gingivitis at natural teeth. Reversible with timely treatment.
Peri-Implantitis (Bone Loss)
What it is: Inflammation with bone loss around the implant — analogous to periodontitis at natural teeth. Not spontaneously reversible without treatment.
Mechanical Complications — Screw Loosening
What it is: The screw that fixes the crown or abutment to the implant becomes loose.
Implant Fracture (Very Rare)
What it is: Fracture of the titanium implant itself.
Progressive Bone Loss Without Inflammation
What it is: Bone resorption around the implant without classical inflammatory signs.
Peri-Implantitis — The Detailed Look
Peri-implantitis is the most important late complication in implantology. Since it can lead to implant loss without treatment, a detailed look is worthwhile.
Causes — Who Is at Risk?
The main risk factors are well documented scientifically:
Symptoms — When to Contact Us
Early signs (well-treatable):
Late signs (urgent treatment needed):
Diagnosis at Mikrostomart
Treatment Stages — Marcin's Protocol
Stage 1 — Non-surgical therapy (for early peri-implantitis):
Stage 2 — Surgical therapy (for advanced peri-implantitis):
Stage 3 — Implant removal (last resort, when preservation is not possible):
Prevention — The Most Important Chapter
The best treatment is prevention. With proper aftercare, peri-implantitis is avoidable in most cases. The most important measures:
Professional Aftercare Every 3-6 Months
At Mikrostomart or with your local dentist (on our recommendation). Implant aftercare includes:
Optimal Home Oral Hygiene
Lifestyle Optimisation
What If Complications Occur?
We are available 24/7 via WhatsApp and phone (Marcin and Elżbieta speak fluent English). For urgent cases, we organise initial care — either in Opole with short travel or in cooperation with an implantologist near your home in the UK.
Our treatment warranty covers structural implant problems during the warranty period. Details on the Warranty and Reimbursement page.

Mikrostomart Clinic — Experience and Statistics
Mikrostomart Clinic in central Opole has been led since 2016. We have placed over 1,250 implants and provided care to over 6,000 patients. Current daily treatment statistics are visible live on our homepage from our Practice Management System.
Our peri-implantitis statistics are significantly below the literature average (5-10%) — result of conservative indication, Premium materials, and structured aftercare.
Frequently Asked Questions (FAQ)
How likely is it that my implant will have problems?
With properly indicated treatment and good aftercare: 2-5% probability for late complications within 10 years. For risk patients (heavy smokers, uncontrolled diabetes, previous periodontitis): up to 10-20%. You can actively reduce your risk through professional aftercare every 3-6 months and good oral hygiene.
What is the difference between peri-implantitis and periodontitis?
The mechanisms are very similar (bacterial inflammation with bone loss), but peri-implantitis often progresses more aggressively — the implant-bone interface is more vulnerable than the natural periodontium. Treatment options differ in part, as the implant has no periodontal ligament.
If I have an implant placed in Poland and later develop problems — who treats me?
We remain your contact point. For complications, we offer 24/7 consultation via WhatsApp/phone in English. For urgent procedures, we organise either a short-term appointment in Opole (2 hours flight from London) or refer you to an implantologist near your home in the UK. Our Treatment Warranty applies long-term.
Can I completely prevent peri-implantitis?
Not to 100% — even with perfect aftercare, complications can occur in rare cases. But you can reduce your risk by 70-80% through: regular professional aftercare, excellent oral hygiene, smoking cessation, well-controlled diabetes, bite guard for grinding.
How long does an implant typically last?
With good care and no complications: 20-30+ years — many patients have their implants for life. The crown on the implant typically lasts 15-20 years and can be renewed if needed, without changing the implant.
What happens if an implant is lost despite all efforts?
Re-implantation is usually possible after: gentle explantation, 4-6 months bone healing (eventually with bone grafting), new implantation. Re-implantation success rate: 85-90%. We discuss this openly with you if the case occurs.
