Using a bone substitute material to treat furcation defects in molars

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

NA · Göteborg University · NCT06270303

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.

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.

Who should consider this trial

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

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

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

Eligibility criteria

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)
