On panoramic X-ray showing J-shaped (3-wall) bony defect — which type of treatment should you do?

A J-SHAPED (angular/vertical) bony defect with 3 WALLS is the IDEAL candidate for REGENERATIVE therapy (Guided Tissue Regeneration — GTR with bone grafting). Three-walled defects have the best prognosis for regeneration because three bone walls provide a vascular scaffold and contain the graft material. Two-wall defects have intermediate prognosis. One-wall defects are generally treated restoratively or not regenerated. Resective therapy is for horizontal bone loss. A (Regeneration) is correct.
