Bone graft procedures are most successful in treating
1. Furcation involvements
2. Deep, two-wall craters
3. Narrow three-wall defects
4. None of the above
Periodontics
Answer: 3

Bone graft procedures are most successful in treating
1) Furcation involvements
2) Deep, two-wall craters
3) Narrow three-wall defects
4) None of the above
Periodontics
Answer: 3
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.
