Regenerative periodontal therapy in mucogingival surgery for root coverage.

This article illustrates the potential benefits of regenerative periodontal therapy in mucogingival surgery and esthetic dental treatment. Cases are described in which the treatment of soft-tissue recessions and root exposures are treated with surgical procedures where both clinical soft-tissue augmentation and the regeneration of periodontal attachment are obtained. Cases are also presented to illustrate the clinical application of guided tissue regeneration. Resorbable and nonresorbable barriers are placed over the root surface and bone and covered by the overlying flap, which allows the selective repopulation of the lesion by progenitor cells and the inhibition of a long junctional epithelium. Emphasis is placed on regenerative procedures in soft-tissue augmentation, particularly with respect to rationales, techniques, and indications.
