The acquisition and maintenance of the osseointegration are the precondition of the success of implant treatment and the bone quality is made the important factor. It is conceivable that it is extremely important to grasp the bone quality of trabecular bone sufficiently before implant treatment. At present the evaluation of the fixed quantity unable to use to clinical of a possible thing easily about bone quantity the bone quality diagnosis of the trabecular bone before the means of the implant treatment that is carried out and be not able to finish the evaluation of the effective qualitative analysis that substitutes the fixed quantity target or it about bone beam structure. Therefore, the problem was unable to evaluate like the fixed quantity results even if it is related to the correspondence of the convalescence of the bone quality and implant treatment of trabecular bone. We perceived it to the method that uses a simple X-ray photograph from the diffusion degree and radiation quan … More tity and other viewpoints of the device for the purpose of, that announces the possibility of the bone quality evaluation of the fixed quantity of the trabecular bone that used the mouth inside measurement X-ray photograph, in this research. It is not announced the method that analyzes the image and remove noise at all about the relation between the evaluation parameter and bone quantity and bone beam structure, although I tried to adopt the simple X-ray photograph that is applied to the diagnosis of osteoporosis with the bone and the others It was needed to clarify the relation between the bone regarded as the difference, those evaluation parameters and shooting object from the diagnosis of the osteoporosis that aims to grasp the condition of a systemic bone. Thereupon, I mainly compare and examined the bone beam structure by the bone quantity and μCT by the mouth inside measurement X-ray copy real image analysis result and CT from the position of structure measuring learning about the bone quantity and bone beam structure of the lower jaw bone with this research.

种植体骨整合的获得和维持是种植体治疗成功的前提，而骨质量则是种植体治疗成功的重要因素。可以想象，在种植体治疗前，充分掌握松质骨的骨质量是极其重要的。目前关于骨定量的评价无法轻易地用于临床对所实施的种植体治疗前的松质骨的骨质诊断手段，也无法完成替代骨梁结构的定量指标或其有效的定性分析的评价。因此，即使该问题与骨质量恢复和松质骨植入治疗的对应性有关，也无法像定量结果那样进行评价。从弥散度和辐射量两方面对单纯X线摄影法进行了认识 ...更多信息 本研究旨在揭示口腔内测量X线片定量评价骨小梁骨质量的可能性。关于评价参数与骨量和骨束结构之间的关系，根本没有公布分析图像和去除噪声的方法，尽管我试图采用应用于骨质疏松症诊断的简单X射线照片与骨和其他骨之间的关系，但需要阐明被视为差异的骨之间的关系，这些评价参数和拍摄对象来自于旨在掌握全身骨骼状况的骨质疏松症的诊断。因此，本研究主要对下颌骨骨量和骨梁结构进行了比较研究，并将口内测量X线片的骨梁结构和μCT的骨梁结构与CT从结构位置测量的X线片的骨梁结构进行了比较分析。少
