Research Abstract

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 new 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 new bone and cortical bone formed around implants were investigated using Micro-XRD and EDX.
