The effect of the post diameter design of over dentures attachment on the strss distribution of pulpless dentine was investigated in this study. The optimal post diameter design was computed with a finite element method and analyzed with graphic method. The changes between the dentine stress value and the post diameter was parabola relationship. The optimal diameter of attachment post was 1.55 mm for this study model. The dentine thickness which retained above apical foramen 4 mm was 0.83 mm. This investigation provides a series of valuable parameters for making a post diameter optimal design of over dentures attachment.
