Computer aided analysis in maxillary sinus surgery

Abstract

The focus of this paper is methods of computer simulation of surgery process. Firstly, CT scan digitized images were obtained by using 16-slice CT (GE Light Speed, USA) to scan from the bottom of mandible to the top of skull along the transverse axis. Secondly, maxillary sinus was reconstructed by using Mimics 10.01(Materialise, Belgium) which is professional software of 3D Reconstruction for Medical Images. Then the 3D model in STL format will be inputted into imageware11.1 (Siemens PLM, USA). Using this software, the outer contour of maxillary sinus will be reconstructed into sheet body. Third, the sheet body will be input into UG NX4.0(Siemens PLM, USA). Mucosa, Trabecular and Cortical Bone will be reconstructed by Means of UG NX4.0 Software. The 3D model of bone condenser was built by the same ways. Finally, by using Ansys Workbench program nonlinear finite element analysis is carried out. © 2008 Springer-Verlag.
