§16§The ultimate goal of periodontal therapy includes the arrest of progressive periodontal disease and reformation of those parts of the periodontium that were destroyed by the disease. Another goal of therapy is predictable regeneration of the periodontium at the site of previous breakdown. The regeneration is defined as 'reproduction or reconstitution of a lost or injured part so that the form and functions of the lost structures are restored' . The periodontal regeneration is defined as regeneration of the tooth's supporting structures including alveolar bone, periodontal ligament and cementum over a previously diseased root surface . The new attachment is defined as ' the reunion of connective tissue with the root surface (previously denuded by disease) that has been deprived of its periodontal ligament. The reunion occurs by the formation of new cementum with inserting fibers' .Optimum wound healing following periodontal reconstructive surgery should result in the formation of n §16§ew cementum, periodontal ligament and alveolar bone appropriately covered by the gingival tissue. This book discusses the different aspects of guided tissue regeneration.
