Objective: To provide a valid model for biomechanics researches of the post-core and PFM complex by constructing three- dimensional finite element model. Methods: SCT scanning technology was used in combination with self-fabricated software, Solidworks software and FEMAP software. Results: The constructed model simulated the morphology and mechanical characters. weir with high quality of mesh and easy operability. Conclusions: A valid three- dimensional finiteelement model can be constructedby combination of CT technology, digital imageprocessing technology and finite element method, which provide measures to oral biomechanical researches and optimizes optimum design of restoration.
