Treatment of Class II furcation lesions using an autogenous periosteal barrier.

Over the last two decades, guided tissue regeneration has achieved significant advances in periodontal healing that confirm the efficacy of periodontal regeneration. Several types of barriers have been utilized to apply this principle to periodontal wound healing. The objective of this article is to review the literature and principles of guided periodontal tissue regeneration (GPTR) in the treatment of Class II furcation defects and to describe a surgical technique that utilizes the neighboring periosteum of the furcation lesion as a barrier for the clinical application of GPTR.
