New attachment achieved by conventional periodontal surgery performed to gain access to diseased root surfaces and to remove local factors such as plaque and endotoxins, usually results in the formation of long junctional epithelium. On the contrary, guided tissue regeneration procedure in which a barrier is used to exclude gingival epithelium and connective tissue from the root surface, has been shown to partially regenerate lost periodontal tissues. This case report presents regenerative periodontal treatment of a 38-year-old female attending with a complaint of painless swelling in the mandibular left second molar region. The patient was diagnosed as chronic periodontitis based on clinical and radiographic findings and intrabony defects were observed at teeth #14, #15, #16, #25 and #37. After initial periodontal treatment, flap operation with the principles of guided tissue regeneration was performed for treatment of intrabony defects. After 4-year follow-up period, evidence of bone fill and no sign of recurrence were seen at defect sites. It was concluded that regenerative treatment of intrabony periodontal defects by the use of bovine xenograft and collagen membrane combination provides favourable clinical and radiographic outcomes in chronic periodontitis patients and could beined up to 4 years successfully.
