| Abstract: | Objective To construct 3-D finite element model of craniofacial complex in rapid maxillary expansion.Methods Raw DICOM data of 2-D images of craniofacial complex were got by spiral CT scan,and with softwares of Mimics10.0,ProE Wildfire 4.0,MSC.Marc.mentat 2005R3 and Geomagic Studio10.0,the 3-D finite element model of craniofacial complex including maxillary first premolar,first molar and their periodontal ligament as well as the band was developed.Results The established 3-D finite element model included 522800 elements.The model had good geometrical similarity and biological similarity,which could be imported to CAD software to process.Conclusions The method to develop a 3-D finite element model of craniofacial complex by CT together with softwares of Mimics10.0,MSC.Marc.mentat 2005 R3 and Geomagic studio10.0 is feasible and effective. |
