1 Scope
This standard covers the material requirements and testing technology of bioglass and glass ceramic used for implants for surgery; the biomaterials listed in this standard may be used for use as bulk porous or powdered surgical implants, or as coatings on surgical devices, but not including drug delivery systems. The biological response to bioglass and glass ceramic biomaterials in bone and soft tissue has been demonstrated in clinical use and laboratory studies.
This standard excludes synthetic hydroxylapatite, hydroxylapatite coatings, aluminum oxide ceramics, alpha- and beta-tricalcium phosphate, and whitlockite.
