Guided Tissue Regeneration – A Boon to Surgical Periodontal Therapy

Abstract

Periodontitis has been a chronic inflammatory disease of the gingiva which eventually result in periodontal pocket formation with loss of the associated periodontal ligament and alveolar bone around teeth. Guided tissue regeneration (GTR), which is often a target for periodontal treatment, has the ability to promote periodontal regeneration. The development of the periodontal attachment is primarily concerned with tissue regeneration.Based on such concept, guided tissue regeneration is being utilized to varying degree of success to restore periodontal defects. In order to remove epithelium as well as gingival corium from the root and/or existing bone walls on the assumption that they interfere with regeneration, barrier techniques have been applied, using elements like expanded polytetrafluoroethylene, polyglactine, polylactic acid, calcium sulfate and collagen.
