Official title: The Use of a Bone Substitute Material in the Surgical Therapy of Furcation Defects - a Multi-center Randomized Controlled Trial

Run by Göteborg University · NCT06270303 · Data updated 2026-11-12

This study is testing if adding a special bone material during surgery can help people with gum issues in their molars heal better than just the standard treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with at least one molar exhibiting a degree II furcation defect and meeting specific periodontal health criteria.

Probably not a fit

Patients with multiple deep furcation defects or significant vertical attachment loss may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of a bone substitute material in the surgical treatment of degree II furcation defects in molars. It involves 200 patients who will be randomly assigned to receive either standard open-flap debridement or the same procedure with the addition of a bone substitute material. The primary outcome is the closure of the furcation defect, while secondary outcomes include various clinical measurements and patient-reported outcomes. The study will follow participants for up to 10 years to assess long-term effects.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes for patients with furcation defects, potentially leading to better tooth retention and periodontal health.

How similar studies have gone: Other studies have shown promising results with similar approaches, indicating potential for success in this trial.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

Patients should present with at least one surgically accessible molar (in tooth position 6 or 7) diagnosed with a single furcation defect degree II (at any aspect).

Following initial periodontal therapy, teeth to be included should present with one site with furcation defect degree II in combination with:

* Bleeding on probing
* Probing pocket depth of ≥6 mm
* Soft tissue coverage of the furcation entrance Patients should present with a full mouth plaque score ≤25%.

Exclusion Criteria:

* Multiple deep furcation defects (degree II - III) at the same tooth
* Vertical attachment loss \>50% at aspects not facing the furcation defect
* Defects presenting with apico-marginal communication
* Intake of systemic antibiotics within 6 months
* Systemic conditions/medication impeding surgical intervention (e.g. uncontrolled diabetes, immunosuppressive medication)
