Sample preparation will be identical to that fortribasic calcium phosphate as specified in the National Formu-lary (2.3) except that approximately1gofmaterial will bedissolv

22、ckiteAPPENDIXES(Nonmandatory Information)X1. RATIONALEX1.1 Hydroxylapatite is commercially available as a syn-thetic bone-grafting material. As with any implant material, thebioresponse is critically dependent upon the material proper-ties. To achieve reliable biocompatibility these must be knownand

23、 consistent. This material standard provides specificationsfor a biocompatible grade of hydroxylapatite. Trace elementcontent and physical form must be within established biocom-patibility standards.X1.2 It is recognized that a separate performance standardmay be necessary for each end-use product.

24、For this reason,physical and mechanical properties were not specified. Asource of general test methods for ceramics may be found inRef (7).X2. BIOCOMPATIBILITYX2.1 No known surgical implant material has ever beenshown to be completely free of adverse reactions in the humanbody. However, long-term cl

25、inical experience has shown thatan acceptable level of biological response can be expected ifthe materials are used in appropriate applications.F1185032REFERENCES(1) Cranin, A.
