The Fit Consideration of the Denture Manufactured by 3D Printing and Sintering

—In previous study, the shrinkage rate of denture was investigated, and the denture was fixed on the standard mold successfully. However, the shrinkage at the bottom of denture is most important to fit the tooth properly. If the fitness isn’t close enough, the bacterial will get into aperture easily to make the teeth being decayed again. It will make the teeth to be removed completely. In this paper, the cross section of the denture is measured and compared through the 3D printing and sintered to study the fit on the standard mold. The shrinkage rates are then obtained along different directions. The results can be applied to amplify the model of denture for the 3D printing to make the denture more close to the mold. 
