Regenerative Periodontal Therapy in Intrabony Defects and Long-Term Tooth Prognosis

In this chapter, the results from a relatively recently performed systematic appraisal of the literature on the long-term outcome of regenerative periodontal treatment in intrabony defects are presented. Periodontal regenerative procedures in intrabony defects yield significantly better clinical outcomes compared with conventional surgery and result in high rates of tooth retention on a medium- to long-term basis. Combination approaches seem, in general, more efficacious compared with monotherapy.
