Purpose:
To investigate the influence of stress on three-dimentional finite element models of maxillary first premolar with multifactors:cavities designs,restored materials,basing materials and loading sites.
Methods:
Three dimensional finite element models for maxillary first premolar with different types cavity which were filled with different basing materials and restoration were constructed and the maximum main stress was measured according to factorial design.ANSYS9.0 software were employed,and the data was statistically analyzed with SPSS 13.0 software package for multivariate ANOVA.
Results:
Loading sites,cavity designs,restored materials and basing materials had effects on stress. Loading sites were the most important factors. Basing materials only had effect on occlusal stress. Cervix region was one of the stress concentration sites.
Conclusions:
Loading site has significant influence on stress,cavity designs,restored materials must be considered during restorations. Supported by Key Research Project of Science and Technology Commission of Liaoning Province (Grant No. 99225008).
