Guided tissue regeneration in periodontal therapy.

In teeth where continued function requires additional periodontal support, optimal treatment requires not only controlling periodontal infection, but also regeneration of periodontal support lost to periodontal disease. Today, guided tissue regeneration (GTR) is a technique with significant clinical and histologic documentation of periodontal regeneration. This paper will address GTR barriers and clinical indications for using these materials to successfully regenerate the periodontium.
