The aim of this study was to evaluate differences in bones quality between newly formed bone and cortical bone formed around titanium alloy implants by using X-ray photoelectron spectroscopy. As a result of narrow scan measurement at 4 weeks, the newly formed bone of C1s, P2p, O1s, and Ca2p were observed at a different peak range and strength compared with a cortical bone. At 8 weeks, the peak range and strength of newly formed bone were similar to those of cortical bone at C1s, P2p, and Ca2p, but not O1s. The results from this analysis indicate that the peaks and quantities of each element of newly formed bone were similar to those of cortical bone at 8 weeks, suggestive of a strong physicochemical resemblance.
本研究的目的是通过使用X射线光电子能谱来评估新形成的骨与钛合金植入物周围形成的皮质骨之间的骨质量差异。4周时进行窄扫描测量的结果显示，与皮质骨相比，新形成骨的C1s、P2p、O1s和Ca2p在不同的峰范围和强度处被观察到。8周时，新形成骨在C1s、P2p和Ca2p处的峰范围和强度与皮质骨相似，但在O1s处不相似。该分析结果表明，新形成骨各元素的峰和数量在8周时与皮质骨相似，提示存在很强的物理化学相似性。
