Chemical Requirements4.1 Bulk compositions shall be tested using Test MethodC 169.4.2 The concentration of trace element levels in the bioac-tive glass and glass-ceramics shall be limited as follows:Element ppm, maxArsenic (As) 3Cadmium (Cd) 5Mercury (Hg) 5Le

21、ad (Pb) 30total heavy metals (as lead) 50Either inductively-coupled plasma/mass spectroscopy (ICP/MS) (18), atomic absoprtion (AAS), or the methods listed in2.3 and 2.4 shall be used.5. Physical Characterization5.1 The following physical and mechanical characteriza-tions may be applicable to various

22、 bioactive glass and glass-ceramics products and should be used whenever possible toverify the material.5.1.1 DensityThe densities of glass and glass ceramicmaterials are related directly to the processing history andcomposition of the material. The density of the bulk materialshall be measured usin

23、g Test Methods C 373 or C 729 and shallbe consistent for the specific materials.NOTE 1This test should use a non-aqueous liquid for bioactive glassand glass ceramic materials, which are known to react in an aqueousenvironment and could thereby affect the measurement.5.1.2 Flexural StrengthWhen used

24、as bulk materials inload bearing applications, the flexural strength of the bulkmaterial shall be measured using Test Methods C 158.5.1.3 Youngs ModulusWhen used as a bulk material,Youngs Modulus of glass and glass ceramic biomaterials shallbe determined following Test Method C 623.5.1.4 HardnessWhe

25、re applicable, for characterization ofthe material, the hardness of bulk samples shall be determinedusing Test Method C 730. The Knoop indentation hardness isone of many properties that is used to characterize glasses.Attempts have been made to relate Knoop hardness to tensilestrength, but no genera

26、lly accepted methods are available. Suchconversion is limited in scope and should be used with caution,except for special cases in which a reliable basis for conversionhas been obtained by conversion tests.5.1.5 Surface AreaThe surface area of a particulate maybe important in determining the reliabi

27、lity of the bioactivity ofthe material. Whenever the specific surface area of the materialrelates to function, the surface area of particulate glass andglass ceramic biomaterials shall be measured using TestMethod C 1069.5.1.6 Bond Strength of Glass or Glass Ceramic CoatingWhen used as a coating on

28、a metallic or ceramic substrate, thebond strength of the coating shall be measured following TestMethod C 633.5.1.7 CrystallinityFor glass-ceramic biomaterials, thepercent crystallinity and crystal phases present in glass ceramicbiomaterials shall be determined by means of X-ray diffractionanalysis.

29、 While there is no single standard method for deter-mining the crystallinity and crystal phases of glass ceramicmaterials, techniques such as those detailed in Refs (19) and(20) should be followed to standardize methods as much aspossible.5.1.8 Thermal ExpansionThermal expansion shall bemeasured usi

30、ng Test Method E 228, when materials are to beused for coatings (raw materials are to be measured), or onfinished product as a quality control test.5.1.9 Particle SizeWhen used as a particulate, the particlesize shall be measured in accordance with Test Methods C 958or C 1070.6. Biocompatibility6.1

31、Glass and glass-ceramic biomaterials should be evalu-ated thoroughly for biocompatibility before human use. Bio-active glass and glass-ceramic materials are unique in theirmode of action when implanted in the body due to the releasedionic species and the mechanisms by which these materialsbond with

32、bony tissue. These materials have been found toexhibit an excellent tissue response in laboratory studies(13-17) and clinical usage (1-12).

36、nd glass-ceramic materials areavailable commercially as synthetic graft materials for main-tenance of the alveolar ridge; as devices for spinal fusion; asimplants for replacement of the vertebral body, iliac crest, andossicular chain of the middle ear; as bone filler to substitute forbone defects re

37、maining after the excision of bone tumors andextraction of loosened joint prostheses; and as coatings ondental and orthopedic implants. As with any implant material,the bioresponse is critically dependent on the material proper-ties. To achieve reliable biocompatibility, these properties mustbe know

This specification provides specifi-cations for biocompatible grades of bioactive glass and glass-ceramics.X1.2 In order to be called bioactive, the materials mustdemonstrate that living tissue is bonding to a significantlyhigher level than non-bonding implant control, as well asde

39、monstrate that ionic species are released from the materialinto solution in a controlled and reproducible manner.X1.3 Bioactive glass and glass-ceramic materials are gen-erally silicate-based materials, with additions of oxides ofcalcium, phosphorous, and various alkalis. They may bephosphate-based

40、materials as well. These materials may alsoinclude fluoride and other alkaline earth metals. Table X1.1gives a few specific examples of the bioactive glass andglass-ceramic materials produced. Since the compositions ofthese materials may vary greatly from product to product, it isnot possible to spe

41、cify their exact compositions.X1.4 It is recognized that separate performance standardsmay be necessary for each end-use product. Physical andmechanical properties were not specified for this reason. Asource of general test methods for glass and ceramic materialsmay be found in the Annual Book of AS
