| Abstract: | ? Objective:To discuss new way of analysing dental maxilla model by three dimensional finite element method.Methods:In this experiment,three dimensional finite element models were established with computer tomography image technique and engineering scanning system.Auto CAD and super SAP softwares were used to analyse the model.Results:By using the accurate,high and similar results of the CT technique and the integrity results of the engineering scanning system,we could accurately copy the two dimensional image of the model and imitate the real condition of oral tissue structures.Conclusion:Three dimensional finite element is simpler,more efficient and more accurate than other methods. 〔 |
