NCT06252935

Brief Summary

The goal of this clinical trial is to evaluate clinically and radiographically effectiveness and products safety of the collagen membrane (FormaAid®) in the treatment of periodontal regeneration using guided tissue regeneration (GTR) performed by the trained periodontists. The main question it aims to answer are:

  • The difference of periodontal status: clinical attachment level (CAL), periodontal pocket depth (PPD), gingival recession (GR), gingival Index (GI) and plaque index (PI).
  • The difference of intrabony defect height.
  • The difference of gingival tissue thickness and gingival tissue volume.
  • The incidences of safety indicators. Participants will be randomized into either experiment group or control group, undergo guided tissue regeneration (GTR) surgery at week 1, and re-visited on week 3, 5, 13 and 27 after the GTR surgery. Researchers will compare if the test product is non-inferior to Bio-Gide.

Outcome Measures

Primary Outcomes (1)

  • Difference of clinical attachment level (CAL)

Secondary Outcomes (8)

  • Difference of periodontal pocket depth (PPD)

    Week 0, Week 27

  • Difference of gingival recession (GR)

    Week 0, Week 27

  • Difference of gingival index (GI)

    Week 0, Week 5, Week13, Week 27

  • Difference of plaque index (PI)

    Week 0, Week 5, Week13, Week 27

  • Difference of intrabony defect height

    Week 0, Week 27

  • +3 more secondary outcomes

Study Arms (2)

FormaAid group

EXPERIMENTAL

Patients with intrabony defects are randomly assigned to receive either FormaAid collagen membrane or Geistlich Bio-Gide (control)before the GTR. And then treated with GTR surgery, the surgical procedure involves a full-thickness flap, the affected area is cleaned, and the damaged or diseased tissue may be removed. The allograft will be then placed into the defect and the collagen membrane is then trimmed and adapted over the defect. After all the treatment is done, 5-0 nylon suture will be used for the flap closure.

Device: FormaAid

Bio-Gide group

Device: Bio-Gide

Interventions

FormaAidDEVICE

FormaAid is mainly composed of pure collagen extracted from bovine tendon, it is fabricated in the form of highly dense collagen matrix without chemical cross-linking to act as a barrier excluding epithelium.

FormaAid group
Bio-GideDEVICE

Bio-Gide is a bilayer collagen membrane made of porcine collagen, permits prompt and homogeneous vascularization and so brings about optimal tissue integration and wound stabilization.

  • Patients who have decided to pay at their own expense and require guided tissue regeneration (GTR) for periodontal regeneration
  • The defect morphology of intrabony defects is 2 or 3 wall intrabony defect.
  • Periodontal pocket depth ≥ 5mm (probing periodontal depth, PPD, distance from gingival margin to the bottom of the defect).
  • The height of the bone defect in the X ray image is ≥ 3mm (according to the X ray film intraosseous defect)
