Abstract

The aim of this study was to assess stress/strain of different implant modeling simplifications by 3D-FEA. Three variation of external hexagon implant (O3.75x10mm) supporting one molar crown were simulated: A (no threads); B (slightly threads simplification); C (original design). 200N (axial) and 100N (oblique) were applied. Cortical bone was evaluated by maximum principal stress and microstrain qualitatively and quantitatively (ANOVA and Tukey post hoc (p<0.05)). Higher stress levels (p<0.05) were observed in model A. Models B and C presented similar stress transmission. It was possible to conclude that slightly simplification should be used for studies evaluating stress transferring for bone tissue. (AU)
