Sequential regenerative therapy using biologic-based regeneration and connective tissue graft wall technique for a severe infrabony defect: A case report.

Researchers treated a severe bone defect around an upper premolar using a two-stage approach: first combining a bone graft with growth factor, then connective tissue grafting. The tooth, initially marked for extraction, was preserved with improved bone fill and gum recession coverage.
