Non-surgical Treatment of Peri-implant Pockets With H42 (H42)

28. september 2026 oppdatert av: Bioteck S.p.A.

This prospective, observational study evaluates the efficacy and safety of H42 non-surgical treatment for peri-implant pockets. The trial involves 56 patients, with 28 subjects receiving the H42 treatment and 28 acting as a control group to monitor soft tissue healing and bone level changes.

Clinical outcomes focus on Pocket Probing Depth (PPD) and Silness and Löe Plaque Index (PI) measured at baseline, 1 month, and 3 months. Gingival inflammation, pain intensity on a 0-10 NRS scale, and absence of infection are monitored at baseline, 7, 14, and 21 days, and at 1 and 3 months. Additionally, a five-point tissue assessment evaluates color, suppuration, granulation tissue, bleeding, and incision margins. Radiographic analysis at baseline and 3 months uses standardized periapical x-rays to measure bone level, intra-bony defect height, width, and angulation. Safety is assessed through the continuous registration of adverse events.

Studiepopulasjon

Adult patients diagnosed with peri-implantitis and treated at the Department of Stomatology, Faculty of Dentistry, University of Seville, Spain. Participants are recruited from patients seeking care at the university dental clinic and are allocated to the study groups according to the study protocol and predefined inclusion and exclusion criteria. The study evaluates the adjunctive use of H42 hydrogel in the non-surgical treatment of peri-implantitis using a case-control design.

Beskrivelse

Inclusion Criteria:

  • Men or women with age ≥ 25 and ≤ 65 years.
  • Subjects affected by peri-implant pockets with probing depth (PD) in the range between 6 to 8 mm.
  • Each subject can have from 1 to 5 defects.
  • Subjects willing to provide signed informed consent to clinical investigation participation.

Exclusion Criteria:

  • Use of aspirin and antiplatelet agents a week before treatment.
  • Subjects smokers ≥ 10 cigarettes per day.
  • Subjects presenting current or previous bleeding disorders.
  • Subjects taking or having indications for anticoagulant therapy.
  • Concomitant treatments or procedures to improve gum health over the last six months before the clinical investigation enrolment, such as HA gel treatments, injection of fillers, and surgery.
  • Subjects suffering from infectious diseases, including herpes simplex infection, active hepatitis, or human immunodeficiency virus.
  • Subjects with dental aesthetic surgery in the preceding 12 months before the clinical investigation enrolment.

At 1 month and 3 months in comparison with the baseline value
Plaque Index (PI)
Tidsramme: At 1 month and 3 months in comparison with the baseline

For each tooth, the four-point scale Silness and Löe Plaque Index is used (Score 0: Excellent; 3: poor)

At 1 month and 3 months in comparison with the baseline
Degree of inflammation
Tidsramme: Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up

Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up
NRS scale
Tidsramme: Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up

Numeric Rating Scale is a simple, reliable tool used to measure pain intensity on a scale from 0 to 10 (0: no pain; 10: maximum pain)

Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up
Absence of infection
Tidsramme: Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up

Clinical evaluation to assess the absence of infection, specifically defined as the absence of suppuration (pus formation), at the treated site as evaluated by the Investigator.

Baseline and 7 days, at 14 days, at 21 days, at 1 month and 3 months of follow-up
