treatment strategy for guided tissue regeneration in various class ii furcation defect: case series

periodontal regeneration is a main aspect in the treatment of teeth affected by periodontitis. periodontal regeneration in furcation areas is quite challenging, especially when it is in interproximal region. there are several techniques used alone or in combination considered to achieve periodontal regeneration, including the bone grafts or substitutes, guided tissue regeneration (gtr), root surface modification, and biological mediators. many factors may account for variability in response to regenerative therapy in class ii furcation. this case series describes the management of class ii furcation defect in a mesial interproximal region of a maxillary tooth and other with a buccal class ii furcation of mandibular tooth, with the help of surgical intervention including the gtr membrane and bone graft materials. this combined treatment resulted in healthy periodontium with a radiographic evidence of alveolar bone gain in both cases. this case series demonstrates that proper diagnosis, followed by removal of etiological factors and utilizing the combined treatment modalities will restore health and function of the tooth with the severe attachment loss. key words: class ii furcation, guided tissue regeneration, maxillary mesial furcation
