What this trial studies

This clinical trial evaluates the effectiveness of non-surgical treatments for peri-implantitis by comparing conventional ultrasonic debridement with a laser-assisted approach. Patients diagnosed with peri-implantitis at the Postgraduate Periodontology Clinic of Aristotle University of Thessaloniki will be randomly assigned to receive either ultrasonic treatment or treatment with Er:YAG and Diode lasers. The study will assess clinical, microbiological, and metabolomic outcomes over a 3-month period, including pain levels and patient satisfaction. Microbial samples and peri-implant crevicular fluid will be collected for analysis before and after treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a diagnosis of peri-implantitis in at least one implant and no active periodontal disease.

Not a fit: Patients with uncontrolled systemic diseases, recent peri-implantitis treatment, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective and less invasive option for managing peri-implantitis.

How similar studies have performed: Other studies have shown promising results with laser-assisted treatments for periodontal conditions, suggesting potential success for this approach.

Eligibility criteria

Inclusion Criteria:

* Patients presenting at the Postgraduate Periodontology Clinic with a diagnosis of peri-implantitis in at least one implant, based on the 2018 classification of periodontal and peri-implant diseases (EFP 2018). Only implants with a probing pocket depth (PPD) of up to 10 mm will be included.

Periodontally healthy individuals (no active periodontal disease). Implants must have been in function (loaded) for at least one year. Age ≥ 18 years. Medically healthy individuals or those with well-controlled systemic conditions.

Implant-supported restorations must be accessible for proper oral hygiene. Patients must provide signed informed consent for participation in the study. Non-smokers only.

Exclusion Criteria:
