Comparison of Autogenous Periosteal Pedicle Graft and Collagen Membrane in Management of Periodontal Intrabony Defects

Twenty patients suffering from advanced chronic periodontitis were included in this randomized controlled clinical trial. Each subject contributed matched pairs of two- or three-walled intrabony defects. Each pair of periodontal defects were randomly assigned into the experimental group; periosteal pedicle graft guided tissue membrane or the positive control group; bioresorbable collagen guided tissue regeneration membrane. Clinical and radiographic parameters were recorded at baseline and at 6 months postoperatively.

Inclusion criteria

• Severe chronic periodontitis patients with at least two sites with pocket depth ≥ 6 mm and clinical attachment level ≥ 5 mm, with radiographic evidence of bone loss 2- or 3-wall intrabony defect depth ranging from 3 to 6 mm as detected in periapical radiographs
• The facial surface of teeth adjacent to the interproximal defect should be free of extensive recession and marginal bone loss, with at least a 4 to 5 mm band of keratinized gingiva to allow for periosteal manipulation

Exclusion criteria

• Pregnant women
• Subjects had <22 permanent teeth
• Having any given systemic disease
• Taking any type of medication and/or antibiotic therapy during the 3 months before the study
• Received periodontal treatment within the past 12 months
• Current or former smokers
