It is assumed that many female patients who want to have medical examinations for dental implant come of the ages suffering from osteoprosis.Since the bone quality has been just classified and evaluated clinically using X-ray analysis it's standard was not clear. From these reasons, we intended to investigate the relationship between the bone quality and it's metabolism after implantation. This research was conducted by the volunteer 12 patients more than 50 years old. Bone biopsy from implant site, X-ray analysis, pQCT value and Ca and P value in the blood of the patients were evaluated and compared individually around implant at the immediately, 3 months and 1 year after operation. And results were as follows, 1. Compared pQCT value of women in more than 50s years old were difference individually. 2. Interactive relationship between the bone quality, pQCT value and bone scintigraphy of the patients did not recognized clearly. 3. In observation of scintigraphy, bone remodeling and concentration were recognized around implant after 1 month implant placement but there were not differences between individuals.

据推测，许多想进行牙科植入物医学检查的女性患者都是患有骨质疏松症的年龄段，由于临床上骨质量的分类和评价都是通过X线分析进行的，因此其标准并不明确。因此，本研究拟探讨种植后骨质量与骨代谢的关系。这项研究是由12名50岁以上的志愿者患者进行的。分别于术后即刻、3个月、1年行种植体周围骨组织检查、X线片分析、pQCT值、血Ca、P值，并进行比较。结果如下：1. 50岁以上女性pQCT值比较，差异有统计学意义。2.骨质量、pQCT值与骨密度之间的交互关系尚不清楚。3.种植体植入1个月后，骨显像观察到种植体周围骨重建和骨密度增加，但个体间无差异。
