Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.

Hyaluronidase and chondroitinase are enzymes that play a role in the degradation of connective tissue components, including glycosaminoglycans in the periodontal tissues. These enzymes contribute to the breakdown of the extracellular matrix, which is significant in periodontal disease progression.
