| Abstract: | Objective To investigate the stress distribution of normal roots,flared roots of maxillary single root premolar restored with four kinds of post-core crown by three-dimensional finite element analysis. Methods After one intact single root maxillary premolar was scanned with micro-CT,the data was dealt with MIMICS,GEOMAGIC,ANSYS.The three-dimensional finite element models of normal root,flared roots of maxillary premolar restored with four different post-core crowns were established,and the S1 and shear stre... |
