<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">Why is this topic important for you?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">You may have heard that experts have different opinions about this topic. That's because science is often more complex than a simple yes-or-no answer might suggest. In this article, we explain what current research actually shows — in plain language and without leaving out important details.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Peri-implantitis can be treated, but not every therapy is equally well supported by evidence. The key clinical question is choosing the right approach for the specific situation.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Why does this matter to you? Because you can make better decisions as a patient when you understand the background. This article is not a replacement for talking with your dentist, but it gives you the knowledge to ask the right questions.</p>
<p style="margin:0;color:#3b362f;line-height:1.82;">In research, the most important questions focus on these areas: Non-surgical vs. surgical, decontamination and surface treatment, long-term success and recurrence risk. For each of these areas, we explain what the studies show and what it means for your daily life.</p></section>
<section style="margin:0 0 32px 0;"><article style="margin:0 0 28px 0;">
<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What is better: Non-surgical or surgical?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">One of the most common questions patients ask about this topic concerns non-surgical vs. surgical treatment. The answer is not as simple as you might hope — but research now provides clear guidance.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The EFP S3 guideline (West et al. 2024) defines a clear step-by-step approach: Non-surgical therapy using mechanical biofilm removal is the first treatment step for peri-implantitis. The guideline is based on the GRADE-ADOLOPMENT framework and was developed by a representative panel including prosthodontics, implantology, and oral surgery. Mechanical cleaning alone shows limited effectiveness for advanced damage, which is why surgical treatment is recommended when deep pockets persist and bone loss continues.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Surgical therapy includes bone removal and bone regeneration approaches. Bone removal procedures aim to eliminate the problem area around the implant through bone reshaping and gum flap surgery. Bone regeneration procedures using bone replacement materials and membranes are used for suitable defects. The EFP guideline recommends surgery for patients who do not respond well enough to non-surgical treatment, with the type of defect determining whether bone removal or regeneration is best.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The point at which to switch from non-surgical to surgical treatment is not clearly defined for everyone. Schwarz et al. (2012) reviewed 75 scientific publications on ligature-induced peri-implantitis in animal models and found significant differences in how studies were conducted: The active breakdown period averaged 14.3 ± 6.4 weeks, followed by a progression period of 5.5 ± 10.4 weeks, resulting in an average bone loss of 40.0 ± 14.0% of the implant length. This variation in experimental methods reflects the clinical uncertainty about when to move to the next treatment step.</p>

<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The clinical decision between non-surgical and surgical treatment is also influenced by patient factors: smoking status, gum disease (periodontitis) history, general health conditions, and how well you follow treatment plans determine how well your individual treatment works. The EFP guideline emphasizes that the treatment decision should not depend only on how deep the defect is, but on a comprehensive risk assessment tailored to you.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">It's important to note that the studies reviewed vary considerably in their design, how long patients were followed up, and which groups of patients were studied. This variation limits how much we can directly compare the results and explains why combined results must be interpreted carefully. However, the overall direction of the findings is consistent across different types of studies.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For applying these findings to dental care in German-speaking countries, it's also important to know that much of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in how treatments are paid for, treatment practices, and how patients access care can affect the size of benefits, but this doesn't make the basic findings invalid.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For your dental care, the step-by-step approach is the most important guide: First, non-surgical cleaning to remove harmful bacteria, then re-evaluation after three to six months. If signs of inflammation and bone loss persist, surgical treatment may be needed. The choice of surgical method depends on the shape of the defect.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The real challenge is deciding when to move to the next step—and not waiting too long. Since implant-related gum disease progresses faster than natural tooth gum disease and can speed up suddenly, don't delay your re-evaluation after non-surgical treatment.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In everyday practice, this means: The scientific evidence doesn't give a one-size-fits-all answer, but rather a framework for decisions tailored to you. Your individual health, how well you can follow treatment, your personal risk factors, and your treatment preferences should all be considered.</p>

<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Scientists have studied this topic intensively in recent years. More than 8 scientific studies were reviewed for this article. It's important to understand: Not all studies have the same value. Large, well-controlled studies give more reliable results than small observation studies. Looking at all these different studies together gives us the overall picture we present to you here.</p>

<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What does "decontamination and surface treatment" mean for me as a patient?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">When it comes to decontamination and surface treatment, the research is clearer than many people think. Here's what the latest studies really show.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Mechanical cleaning of the implant surface is the core of any implant-related gum disease treatment. The EFP S3 guideline (West et al. 2024) recommends standard cleaning below the gum line as the basic treatment. Additional methods like lasers, light-based therapy, and antimicrobial rinses are discussed as possible additions, but are not recommended as routine treatments.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">An independent scientific review by Jervøe-Storm et al. (2024) examined light-based antimicrobial therapy as an add-on treatment in 50 studies with 1,407 participants. In active gum disease (periodontitis) treatment, the average difference in pocket depth after six months was 0.52 mm (95% CI 0.31–0.74), bleeding on probing 5.72% (95% CI 1.62–9.81), and clinical attachment level 0.44 mm (95% CI 0.24–0.64) in favor of light-based therapy—all with very low quality evidence. The authors considered these differences as not clinically meaningful.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In the maintenance phase, Jervøe-Storm et al. (2024) found no relevant differences: the average difference in pocket depth was -0.04 mm (95% CI -0.19–0.10), bleeding on probing 4.98% (95% CI -2.51–12.46). For implant-related gum disease, no usable data were available—the review found no studies in patients with implant-related gum disease and only one very small study in patients with implant-related inflammation without six-month data.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">24 studies with 639 participants reported no side effects from light-based therapy (moderate quality evidence). The authors concluded that because the evidence quality is very low, we cannot be sure whether adding light-based therapy leads to better clinical results, and even any possible improvements would be too small to matter clinically.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">It's important to note that the studies reviewed vary considerably in their design, how long patients were followed up, and which groups of patients were studied. This variation limits how much we can directly compare the results and explains why combined results must be interpreted carefully. However, the overall direction of the findings is consistent across different types of studies.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For applying these findings to dental care in German-speaking countries, it's also important to know that much of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in how treatments are paid for, treatment practices, and how patients access care can affect the size of benefits, but this doesn't make the basic findings invalid.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In practice, mechanical cleaning should be the main focus. Add-on methods like light-based therapy, lasers, or chemical additions can be discussed as extra options in individual cases, but should not be recommended as routine treatment since the evidence does not prove they provide meaningful additional benefit.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Your dentist should discuss the costs of add-on treatments: Buying laser or light-based therapy equipment is expensive, while proven additional clinical benefit is small or not proven.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In everyday practice, this means: The scientific evidence doesn't give a one-size-fits-all answer, but rather a framework for decisions tailored to you. Your individual health, how well you can follow treatment, your personal risk factors, and your treatment preferences should all be considered.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for you? Recommend additional procedures only when supported by research evidence.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for your next dental visit? These research findings help you better understand your dentist's recommendations and ask specific questions if something isn't clear.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">How do scientists reach these conclusions? They don't look at just one study, but examine many studies at the same time. This way they can see whether a result was due to chance or whether it appears again and again. In this case, the findings are based on 8 scientific studies from different countries and research groups.</p>

<article style="margin:0 0 28px 0;">
<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What does "long-term success and risk of recurrence" mean for me as a patient?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">One topic that often causes uncertainty is long-term success and risk of recurrence. However, science has made important progress in recent years.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Long-term results of peri-implantitis treatment are characterized by a high recurrence rate. The EFP S3 guideline (West et al. 2024) emphasizes that peri-implantitis can progress after treatment in a non-linear, accelerating pattern if supportive peri-implant therapy (dental follow-up care) is not provided. The progression rate is typically faster than with gum disease (periodontitis).</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The cost analysis in the EFP guideline shows the economic perspective: A Swedish study with 514 patients calculated average costs over 8.2 years of 878 euros (single tooth restoration) to 1210 euros (full arch restoration). The largest share of costs went to prevention (741 euros), while implant loss was the most expensive complication (1508 euros), followed by peri-implantitis (1244 euros). The additional costs of implant maintenance were five times higher than those of tooth maintenance.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">A cost-effectiveness analysis modeled the 20-year course of individual implants and showed that skipping annual dental follow-up care increased the risk of peri-implant disease. Providing dental follow-up care was cost-effective, especially for high-risk patients. For non-surgical treatment, instrumentation alone, air-polishing, and the combination of instrumentation with local antiseptics/antibiotics were more cost-effective than Er:YAG laser, Vector system, or photodynamic therapy.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Follow-up care compliance is the crucial predictor for long-term success. Patients with a history of severe gum disease (periodontitis), poor plaque control, and lack of regular dental follow-up care have a consistently increased risk of peri-implantitis recurrence. Smoking and diabetes are additional risk factors, though the scientific evidence for these is less consistent than for lack of follow-up care.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Methodologically, it is important to note that the included studies vary considerably in study design, follow-up period, and population selection. This variation limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different types of studies.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For transferability to German-speaking dental care systems, it is also relevant that a significant portion of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in reimbursement structure, treatment culture, and patient access can influence effect sizes without invalidating the basic findings.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The clinical conclusion is clear: Treating peri-implantitis means managing it long-term. Treatment does not end with the surgical procedure, but requires structured follow-up care for life. The follow-up interval should be adjusted to individual risk — for high-risk patients every three to four months, for stable patients every six months.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Already during treatment planning, the long-term costs of follow-up care should be communicated transparently. Patients who can afford the implant but do not plan for follow-up care carry a structurally increased risk of complications.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In daily practice, this means: The scientific evidence does not provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be included in the decision-making process.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for you? Treatment success must be thought of together with follow-up care commitment.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for your next dental visit? The research findings help you better understand your dentist's recommendations and ask targeted questions if something is unclear.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What makes these results reliable? In medical research, the principle is: the more independent studies that reach the same conclusion, the more certain the statement. The type of study and the number of participants also play an important role. Large controlled studies with many participants provide more reliable results than small surveys.</p>
