Marching cubes (MC) algorithm is a typical representative for surface reconstruction method

however

there are still some shortcomings about the topology structure and the represent accuracy of the isosurface which extracted by MC algorithm

and so does the algorithm’s execution efficiency. Thus

based on the continual characteristic when the isosurface past the cubes

one improved MC algorithm is proposed

which can shorten the execution time obviously. And its realized in visualization tool kit (VTK). The experiment showed that the stomatognathic reconstruction time can decline to 58s. A new medical 3D reconstruction system for stomatognathic is also developed based on the improved MC algorithm. The application instances show that the improved MC algorithm is efficient and robust

which can be applied successfully in 3D reconstruction for complex curved surface of stomatognathic.
