Bone Graft
The transplantation or implantation of bone material — autogenous, allogeneic, xenogeneic, or alloplastic — to augment deficient jaw bone volume prior to or concurrent with implant placement.
Full Definition
A bone graft in oral surgery refers to the surgical placement of osseous material into a defect, socket, or sinus to restore or augment bone volume. Graft material may be autogenous (harvested from the patient's own body), allogeneic (from a human donor), xenogeneic (from an animal source, typically bovine), or alloplastic (synthetic). Editors must apply precise terminology when specifying graft type, as the distinctions carry clinical, regulatory, and medicolegal weight. Common graft-specific terms include 'socket preservation graft', 'ridge augmentation', and 'sinus lift'; these should not be used interchangeably with the generic term 'bone graft' without qualification.
Usage
Usage note: Always qualify 'bone graft' with its source type (autogenous, allograft, xenograft, alloplast) in formal surgical documentation.
