| Abstract: | Objective To study stress distribution of dental zirconia layered structure.Methods On the constructed three-dimensional finite element model of zirconia layered structure of the first maxillary molar,veneer layer is 70 GPa and 1.5mm,core layer is 205 GPa and 0.5 mm,respectively.Load of 200 N was applied over a 1mm diameter circle at the tip of the mesial-distal cusp ridge,simulating typical occlusional contact areas.Then maximum principal stress was calculated.Results The maximum principal stress varied th... |
