Bone Density
A qualitative or quantitative measure of the mineralisation and structural quality of alveolar bone, commonly classified by the Lekholm & Zarb scale (D1–D4) for implant planning purposes.
Full Definition
Bone density in implantology refers to the quality and mineralisation of the alveolar bone at a prospective implant site, which directly influences primary stability, osseointegration potential, and the choice of surgical protocol. The Lekholm and Zarb classification (D1 through D4, from densest cortical to predominantly soft cancellous bone) remains the most widely cited editorial reference. Editors must note that 'bone density' is a clinical/radiographic descriptor and should not be confused with 'bone volume', which refers to the quantity rather than quality of bone. Authors writing for radiological journals may use Hounsfield Units (HU) as an objective measure; editors should ensure these two measurement systems are not conflated.
Usage
Usage note: Distinguish clearly from 'bone volume'. When HU values are cited, ensure units are included.
