Outline of Final Research Achievements |
Biological apatite(BAp) crystallite c-axis alignment is known to be a factor in the mechanical fanction of bone. The aim of this study was to specify the region of jaw bone affected by occlusal force and evaluate mechanical function of bone quantitatively using crystallographic approach. A microbeam X-ray diffraction system was used to determine BAp crystallite alignment along the tooth axis and implant longitudinal axis. Young’s modulus along the same direction in the sites was also measured with nanoindentation and the relationship between BAp crystallite alignment and Young’s modulus was examined. The results suggested that the funictional pressure typified by occlusal force affected nanostructure of jaw bone. Moreover, determination of BAp crystallite alignment may also useful in predicting the effects of mechanical environment of human jaw bone in a high accuracy.
