Cavity liner of ultramicronized hydroxyapatite, Ca10(PO4)6(OH)2 (UMHA) (crystal diameter: 0.2-1.0 micron, range 70) suspended in a rapidly evaporating mixture: 50 diethyl ether e.g. 34.6 degree C and 50 ethyl acetate, e.g. 76.5

摘要

The special features of the invention comprise: 1) the addition of ultramicronized hydroxyapatite (UMHA) (70% of the microcrystals having a diameter of between 0.2 and 1.0 microns) to various conventional cavity liners, 2) formulation of a rapidly evaporating mixture of 50% diethyl ether and 50% ethyl acetate. The qualitative/quantitative composition according to the invention incorporates and combines the features mentioned in paragraphs 1) and 2) above. 1 bottle contains: ultramicronized hydroxyapatite: UMHA 460 mg calcium hydroxide 724 mg zinc stearate 36 mg zinc oxide 180 mg excipient: titanium oxide, copahu, ethenyl benzene homopolymer q.s. analytical ethyl acetate, diethyl ether to 10 ml.
