DFDBA
Pronunciation: D-F-D-B-A
Also written as: DFDBA — Demineralised Freeze-Dried Bone Allograft
Demineralised freeze-dried bone allograft; a processed human donor bone graft with mineral content removed to expose osteoinductive proteins.
Full Definition
DFDBA is produced by demineralising freeze-dried bone allograft (FDBA), a process that removes the inorganic mineral matrix and exposes collagen and bone morphogenetic proteins believed to confer osteoinductive properties. It is widely used in periodontal osseous defect management and ridge preservation. Editors must distinguish DFDBA from FDBA (freeze-dried bone allograft), which retains its mineral content and acts primarily as an osteoconductive scaffold. Both acronyms appear frequently in periodontal literature and are easily transposed.
Usage
Usage note: Always spell out on first use. A critical confusable pair with FDBA. Editors must verify the correct acronym against the described material.
In Context
- "DFDBA was placed in the three-wall intrabony defect in combination with a resorbable membrane." — Surgical case report
- "Authors should not interchange FDBA and DFDBA; the demineralisation process fundamentally alters the material's biologic activity." — Journal style note
