FDBA
Pronunciation: F-D-B-A
Also written as: FDBA — Freeze-Dried Bone Allograft
Freeze-dried bone allograft; a processed human donor bone that retains its mineral content and acts as an osteoconductive scaffold.
Full Definition
FDBA is produced by freeze-drying cadaveric bone to remove water and reduce antigenicity while preserving the mineral hydroxyapatite structure. Unlike DFDBA, it is not demineralised and therefore functions primarily as an osteoconductive scaffold rather than an osteoinductive agent. FDBA is commonly used in ridge preservation, sinus augmentation, and intrabony defect fill in periodontal surgery. The distinction between FDBA and DFDBA is a frequent source of error in manuscript preparation and must be verified at editing stage.
Usage
Usage note: Spell out on first use. FDBA and DFDBA are a high-risk confusable pair in periodontal manuscripts; always cross-check the acronym against the described material properties.
In Context
- "FDBA was used for socket grafting following extraction to preserve ridge dimensions." — Case report
- "The abstract states FDBA has osteoinductive properties; this claim should be queried as FDBA is osteoconductive, not osteoinductive." — Peer-review editorial note
