About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age between 18 70 years old, male or female

Non current smoker: A person who has not smoked more than 100 cigarettes from the past to the present and has not smoked in the last 30 days.

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.

Disqualifiers

Have a history of severe allergies or be allergic to collagen.

Those who are known to be positive for human immunodeficiency virus.

Undergoing chemotherapy three months before agreeing to this experiment.

Trial design

Design model

Parallel

Treatments tested in this trial

  • FormaAid

    Device

    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.

  • Bio-Gide

    Device

    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.

Treatment groups

60 Participants
are divided into 2 treatment groups
Group A: FormaAid groupExperimental treatment 1 intervention
Group B: Bio-Gide groupActive comparator 1 intervention

Trial outcomes

Primary outcomes

1

Difference of clinical attachment level (CAL)

Difference from baseline in periodontal clinical attachment level (CAL) with a periodontal probe Week 27 after the surgery. CAL is defined as periodontal probing depth plus gingival recession.

Time frame
Week 0, Week 27

Secondary outcomes

1

Difference of periodontal pocket depth (PPD)

PPD is assessed by periodontal probing to detect and measure the distance from gingival margin to the bottom of the defect. Difference from baseline in periodontal pocket depth (PPD) Week 27 after the surgery.

Time frame
Week 0, Week 27
2

Difference of gingival recession (GR)

GR is assessed by periodontal probing to detect and measure the distance from the gingival margin to the cemento-enamel junction (CEJ). Difference from baseline in periodontal Gingival recession (GR) Week 27 after the surgery.

Time frame
Week 0, Week 27
3

Difference of gingival index (GI)

Difference from baseline in periodontal status: Gingival Index (GI) Week 5, 13, and 27 after the surgery. GI is evaluated according to Löe \& Silness. * 0: Normal gingiva. * 1: Mild inflammation Slight change in color, slight oedema. No bleeding on probing. * 2: Moderate inflammation: Redness, oedema and glazing. Bleeding on probing. * 3: Severe inflammation: Marked redness and oedema. Ulceration. Tendency to spontaneous bleeding.

Time frame
Week 0, Week 5, Week13, Week 27
4

Difference of plaque index (PI)

Difference from baseline in periodontal status: Plaque Index (PI) Week 5, 13, and 27 after the surgery. PI is evaluated by using the grading definition of Silness \& Löe. * 0: No plaque in the gingival area. * 1: A film of plaque adhering to the free gingival margin and adjacent area of the tooth The plaque may only be recognized by running a probe across the tooth surface. * 2: Moderate accumulation of soft deposits within the gingival pocket, on the gingival margin and/or adjacent tooth surface, which can be seen by the naked eye. * 3: Abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface.

Time frame
Week 0, Week 5, Week13, Week 27
