Natural bioactive gel to treat peri-implantitis around dental implants.

Efficacy of a Natural Bioactive Gel as an Adjunct to Standard Therapy in the Treatment of Peri-Implantitis: A Randomized Controlled Split-Mouth Clinical Trial

NA · University of Pavia · NCT07088679

This study will try adding a natural bioactive gel (Sterify Gel®) to standard non-surgical cleaning to see if adults with peri-implantitis have less inflammation and bone loss around their implants.

What this trial studies

This is a randomized, controlled, split-mouth clinical trial in which each participant serves as their own control: one affected implant will receive standard non-surgical therapy plus a mucoadhesive bioactive gel (Sterify Gel®) and a second implant will receive standard therapy alone. The gel contains polyvinyl polymers, hydroxytyrosol, magnesium ascorbyl phosphate, and the antimicrobial peptide nisin and is applied as an adjunct to mechanical debridement and air-polishing. Twenty patients with at least two implants in different quadrants affected by peri-implantitis will be enrolled and followed for nine months. Clinical outcomes will include plaque levels, bleeding on probing, probing depth, and radiographic measures of bone loss.

Who should consider this trial

Good fit: Adults aged 18–70 with peri-implantitis involving at least two dental implants in different quadrants, clinical signs of bleeding and/or suppuration on probing, and increased probing depth and radiographic bone loss who can attend follow-up visits are ideal candidates.

Not a fit: Patients with only one affected implant, those with excluded conditions (such as implanted electronic devices, uncontrolled systemic or autoimmune diseases, pregnancy or lactation), or those unable to comply with follow-up visits may not be eligible or likely to benefit from this protocol.

Why it matters

Potential benefit: If successful, adding Sterify Gel® could reduce inflammation and pocket depth around implants and help limit further bone loss, potentially lowering the need for more invasive treatments.

How similar studies have performed: Local antimicrobial and bioactive adjuncts for peri-implant and periodontal disease have shown mixed but sometimes promising results in prior studies, while clinical data specific to Sterify Gel® are limited.
