Long-Term Assessment of Combined Osseous Composite Grafting, Root Conditioning, and Guided Tissue Regeneration.

Although the short-term, success of guided tissue regeneration has been widely reported, few studies on the long-term, success of treatment have been published. The present investigation assessed the 5-year results of guided tissue regeneration procedures used alone or in combination with root conditioning and osseous composite grafts. Results indicated that the long-term success of guided tissue regeneration was significantly enhanced by the addition of root conditioning and grafting procedures.
