PURPOSE: To investigate the stress distribution patterns at the bone interface around dental implants. MATERIALS AND METHODS: Using three-dimension finite element method and multivariate step regression analysis, authors analyzed influencing factors on the stress distribution patterns at the bone interface based on the stress magnitudes surrounding dental implant neck. RESULTS: Finding the vital influencing factors of stress distribution patterns at the bone interface around dental implants, obtaining the regression equation, revealing the quantity's relation between the varieties' factors and the stress distribution patterns at the bone interface around dental implant neck. CONCLUSIONS: Cantilever, superstructure bar connecting with the implants and loading angles were the vital important factors of influencing the stress magnitudes at the bone interface around dental implants. When implanting a dental fixture the loading angles were the most important one influencing the stress magnitudes at the bone interface.
