ABSTRACT
Objective:
To compare influence of residual dentin stress on condition of different post length of posterior teeth post-core,to discover reasonable post length of posterior teeth post-core,in order to instruct clinic rational design.Methods:
Models were created by abrasive method and way which pictures were acqiured with digital camera.To generate three-dimensional models of maxillary firster molar which is short in medial palatal cusp restored with post-core crown.Then analyse magnitude and distribution of model residual dentin stress by the three-dimension finite element analysis.Result:
When maxillary firster molar which is short in medial palatal cusp restored with middle fusion metal post-core and porcelain fused mental crown,on condition of 1/2 post length and2/3 post lengths,it has the same magnitude of Von mises stress? most main stress ? least main stress and the same stress distribution on residual dentin.Conclusion:
When maxillary firster molar which is short in medial palatal cusp restored with middle fusion metal post-core and porcelain fused mental crown,on condition of 1/2 post length and2/3 post lengths,it has no infulence in magnitude and distribution of stress of residual dentin.
