Abstract

Abstract High-resolution 31 P and 1H NMR spectra at 40 MHz ( 31P) and 300 MHz ( 1H) of biologically relevant synthetic samples of calcium phosphates and biopsies have been obtained by magic angle sample spinning (MASS) at spinning speeds up to 6·5 kHz and by high power proton decoupling (HPPD). The samples include crystalline hydroxyapatite, a deficient hydroxyapatite characterised by a Ca/P atomic ratio of 1·5, a poorly crystallised hydroxyapatite partially dissolved in EDTA, monetite, brushite, β-tricalcium phosphate, octacalcium phosphate, rabbit bone and human pathologic bones. The resorption of a porous β-tricalcium phosphate plate was studied; within fifty days new ossification accounts for more than half of the implant.
