【Abstract】 Objective To discuss Construction of the three-dimensional finite element model of maxillary central incisor by using CT scanning technique. Methods In this experiment, three-dimensional finite element models were established with CT scanning technique and image process software. Auto-CAD and Ansys softwares were used to analyse the model. Results By using the accurate results of the CT scanning technique, we could accurately copy the two-dimensional image of the model and imitate the real condition of maxillary central incisor. Conclusion Construction of the three-dimensional finite element model by using CT scanning technique is simpler, more efficient and more accurate than other methods.更多还原
