Difference of implant-bone adhesion was influence to concentration of occlusal stress and bone remodeling. In HA-implant, occlusal stress and bone remodeling was mainly performed on alveolar bone which was adhesion to neck part of implant. On the other hand, in Ti-implant, concentration of occlusal stress and bone remodeling was done on mainly cancellous bone around implant bottom. But, difference of a little amount of bone resorption was shown between two kinds of implant under experimental conditions. Therefore, the difference of implant-bone adhesion was suggested a little influence to implant successful clinical course.The most large amount of bone resorption was found under the condition of excessive occlusal stress plus peri-implantitis, and the next large amount bone resorption was found in peri-implantitis. Excessive occlusal stress on implant showed the smallest alveolar bone resorption in experimental group. In control group, the two kinds of implant showed little amount of bone resorption.Peri-implantitis was more influence on bone resorption and bone remodeling than excessive occlusal stress of two kind of implant Therefore, a good control of peri-implantitis is the most important factor for good clinical course of dental implant.

种植体-骨结合力的差异对咬合应力集中和骨改建有影响。HA种植体的咬合应力和骨改建主要发生在与种植体颈部粘连的牙槽骨。钛种植体的应力集中和骨改建主要发生在种植体底部周围的松质骨上。但在实验条件下，两种种植体的骨吸收量略有差异。因此，种植体与骨的粘附力差异对种植体成功的临床过程影响不大，种植体周围炎和咬合应力过大时骨吸收量最大，种植体周围炎时骨吸收量次之。实验组牙槽骨吸收最小。对照组两种种植体均无明显的骨吸收，种植体周围炎对骨吸收和骨重建的影响大于种植体过度的咬合应力，因此，良好的种植体周围炎控制是保证种植体良好临床进程的重要因素。
