GBR
Also written as: GBR — Guided Bone Regeneration
Abbreviation for guided bone regeneration, a surgical technique using barrier membranes to promote new bone formation in jaw defects.
Full Definition
GBR is the standard abbreviation for guided bone regeneration in oral surgical, implantological, and periodontological literature. It is frequently encountered in case reports, clinical guidelines, and product instructions for membrane systems. Editors must not abbreviate GBR as 'GTR' (guided tissue regeneration), which is the analogous periodontal procedure targeting soft tissue attachment rather than bone. The abbreviation should always be defined on first use in any document where a non-specialist reader is anticipated.
Usage
Usage note: Always define on first use. The common confusable GTR (guided tissue regeneration) refers to a different procedure in periodontics; an editor must not substitute one for the other.
