| Outline of Final Research Achievements |
There is a possibility that the diffusion of pro inflammatory fluids from the microgap to the surroundings of the dental implant due to the micromovement would be a causal factor for the reabsorption of peri implant bone. To analyze this condition, a CAD model of an implant body and its respective superstructure were created by means of a CAD software. Then, the tisular fluids around the microgap and its dispersing conditions were simulated by the moving particle semi-implicit method. As a result, the present method confirmed a horizontal and vertical dispersion of the simulated particles from the tisular fluids. The results of the present experiment can be used to visually analyze the behavior of the tisular fluids around the dental implant.
