To achieve the long-term retention and stability of implants under such conditions, the quality of newly formed bone around implants is important. There have been many studies reporting that new bone formed around implants is spongy bone. However, although the morphology is reportedly like spongy bone, it is difficult to discriminate whether the bone quality of newly formed bone is mature like cortical bone, or immature, being similar to spongy bone, osteoid, or cartilaginous bone; therefore, evaluation of the bone quality is required.In this study, differences in the bone quality between newly formed bone and cortical bone formed around implants were investigated using Micro X-ray diffraction (XRD) and Energy Dispersive X-ray (EDX).

为了在这种条件下实现种植体的长期保留和稳定性，种植体周围新形成的骨的质量非常重要。有许多研究报告称，种植体周围形成的新骨是松质骨。然而，虽然据报道其形态类似松质骨，但很难区分新形成的骨的骨质量是像皮质骨那样成熟，还是像松质骨、类骨或软骨骨那样不成熟；因此，需要对骨质量进行评估。在本研究中，利用微X射线衍射（XRD）和能量色散X射线（EDX）研究了种植体周围新形成的骨和皮质骨之间的骨质量差异。
