About this trial

This is an interventional treatment trial for Periodontal Diseases focused on measuring resorbable collagen membrane

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Aged 18 to 65 years, male or female;
  2. patients were clinically diagnosed with chronic periodontitis according to the international classification of periodontal disease in 1999;
  3. Only solitary lesion site requires surgical treatment and must meet the following criteria:

    1. The baseline PD≥7 mm ;
    2. After debridement during operation, the defect of the vertical bone at the adjacent surface ≥4mm, and at least one alveolar buccal wall can be detected;
    3. The wideness of the keratinized gingiva≥2 mm;
    4. Based on the X-Ray image, the dental crowns at the bottom of the bone socket should be at least 3mm;

Exclusion Criteria:

  1. The test tooth has open surgical debridement history within the most recent one years;
  2. Known allergy to collagen of animal origin;
  3. Clinical or radiographic signs of untreated acute infection at the surgical site, apical pathology, root fracture, severe root irregularities, cemental pearls, cemento-enamel projections not easily removed by odontoplasty, untreated carious lesions at the cemento-enamel junction (CEJ) or on the root surface, subgingival restorations and/or restorations with open margins at or below the CEJ;
